Can I Build My WiFi Antenna?

As the number of portable computing and communication devices grew, so does the demand to connect them to outside world. To go on line the computers had to be plugged into a telephone wall socket. Requiring a wired connection to fixed network meant that computers were portable, but not mobile.

To achieve true mobility the computers need to use radio(or wireless in that case) signals for communication. . In this manner, dedicated users would be able to read and send email while driving or moving to other rooms etc. A system of portable computers that communicate by radio are known as wireless LAN. Therefore to provide mobility to the systems, wireless local area networks were developed and now a new technology “Wi-Fi” or 802.11x(IEEE standard for wireless LAN setup), has become the most popular worldwide standard for the wireless communication in LAN.. Nowadays all major Laptop manufacturers provide an in built wi-fi system. Work is being done to make various devices like mobile phones, mp3 players etc to be wi-fi enabled.

In order to meet the growing demand for wi fi networks, various public places are provided with them.

In order to enhance the wireless capabilities the antennas are developed and are now available in the market, though they are easy to install but these antennas are very expensive. Hence it would be a great thing if it is possible to make our own antennas with some readily available goods. We would need a cable (also known as pigtail) to connect wireless interface card with the antenna. We would also need two kinds of connectors, a N-male connector to connect one end of the cable to antennas and an appropriate connector to connect the wireless interface card with cable. Since the making of antenna requires wire, we would also need a soldering iron to solder wires.

ADVANTAGES OF DESIGNING OUR OWN ANTENAS

The construction of our own antennas provides various advantages to us. Apart from being cheaper than the antennas available in market they are also easy to configure into our system. So instead of investing huge amounts of money in antennas we can better manage that money by adding them to buy better Laptop systems.

There is also time factor involved in making your own antennas system. Since it is easy and faster to make and install our own antennas, it saves lot of time. Hence designing and making our own antennas would provide a better facility to the total cost involved in configuring the communication system

3 Ways To Protect Data Privacy

After you delete a "sensitive" file, do you rest assured that nobody will ever be able to access that file? Well, think again... because you are not completely safe until you really remove that file!

What happens is that when you delete a file, this operation is translated as:

* mark the disk space occupied by that file as available, so that other files can use it;

* mark the file as gone from the directory it was in, so it won't be listed anymore;

* leave the actual contents of the file on the disk, so it can be recovered;

...and this is happening in many operating systems, like Windows XP (NTFS), Mac OS X (HFS Plus) or GNU/Linux (with a kernel version greater than 2.4).

The last operation is the one causing problems in some cases, although it has its benefits. But it's not that bad, because, along with new bytes getting written to the disk, that disk space marked as available will be used by other files eventually. So, the content of the deleted file is replaced, making it unrecoverable by software means (I've specified software means, because on older hard disks it's possible to recover a deleted file through physical means and with the right equipment, even if new information has been written on that disk).

If you don't want to wait for that, there are some alternatives:

1. File shredding (preferably on the whole partition rather than individual files - disk free space wiping);

2. store the file using strong encryption at all times, in which case there won't be any useful data to recover (if the encryption key is secure enough);

3. destroy the media (incinerate, use acid, degauss the platters);

These last two are very effective alternatives to protect data privacy, though they are much more that an average user needs. And since using file shredder software is sufficient enough to ensure that the data can't be recovered, I think that's the best alternative to use.

File shredding (also called file wiping) signifies secure deletion of a computer file, so that it can not be restored by any means, and it can be done using specialized software - usually called File Shredder.

Tip: Although your computer is telling you that there is a certain amount of free space on your disk, it doesn't necessarily mean that and it's always a good thing to do a free disk space wipe - some people say that it's even better to do it three times in a row!

Tip 2: Before you decide to buy such software, search the Internet for reviews on the most popular file shredders.

Hope it helps!

Computer Performance Improvement - 8 Tips to Make Your Computer Purr Like a Kitten

SIGNS OF A COMPUTER WITH PERFORMANCE PROBLEMS!

(If this is indicative of your computer, you need help!)

Programs run slower than they used to.

Frequent freezes or crashes.

Sporadic system instability.

Frequent blue error screens.

Requires frequent reboots because of system hangs.

These 8 simple tips will help clean up your computer and you'll be surprised at the performance improvement!

CLEAN UP YOUR WINDOWS REGISTRY

This essential task is often overlooked but will remarkably improve PC performance. Most PC users don't even know there is such a thing as a Registry much less that that it should be regularly cleaned. In fact, Microsoft doesn't even include a cleanup tool in Windows.

Every time a program is installed or uninstalled changes are made to the Windows Registry which is a huge internal database of Windows' settings. All programs, as well as Windows itself, store a huge amount of information in this database and these entries control the way everything in the computer looks and behaves.

Many times, changes to a computer are not handled correctly leading to conflicts and the slowing of the computer due to a corrupted Registry. Some things which can cause this are:

  • frequently installing or uninstalling programs

  • removing a program and leaving traces behind

  • leftover entries from a hardware uninstall

  • power failure or system crash in the midst of updating the registry

  • unused drivers on the system

  • Spyware or Adware type programs that come back every time the PC is restarted

The Registry can be edited manually using a Windows program called RegEdit, but woe to the novice; this is really a job best left to the experts. Instead, you need to use a special program which makes the cleanup for you.

EMPTY THE RECYCLE BIN

Regularly empty the Windows' Recycle Bin thereby releasing hard drive space and helping to improve performance.

When you delete a file, instead of removing it completely from your computer, Windows puts it into the Recycle Bin. You then can restore these flies from the Recycle Bin back to their original place on your computer if you should need to.

REMOVE UNNECESSARY PROGRAMS

If you're like me and download a lot of free programs or free trials, after a while your computer might begin to slow down. That means it's time to remove some of the old programs you don't use any more (and most you probably only used once just to see how they work).

After installing a program, if you decide you don't need it and won't use it, get it off the computer thereby freeing up system resources. Most programs come with their own uninstaller but if it doesn't you will have to use the Operating System's Add/Remove Programs feature which you can get to through The Control Panel.

Uninstalling unused programs will help speed up your computer, but removing the wrong files can cause you some really big problems. NEVER, NEVER EVER just delete a program file by using the delete key; this can really mess up the Registry. Be careful and if you are not sure, ask for help from someone you know who is more experienced. If you are unsure whether or not to remove a program, it's best to leave it.

Some programs leave uninstalled junk all over the Windows Registry! Therefore, to improve PC performance AFTER AN UNINSTALL, IT'S ESSENTIAL TO CLEAN THE REGISTRY.

RUN DISK CLEAN UP

Windows Disk Clean Up is a great built-in utility that automates regular maintenance tasks to improve PC performance. Whenever you "surf the net", open file attachments, delete files, etc., your computer saves a record of your activity. Most if not all of these files are harmless, and are very small. But if you spend a lot of time on your computer, before long they will use up enough space to slow your computer down a tad.

Double-click My Computer, right click on the 'C:' drive, then click Properties, then click Disk Cleanup. The PC will then spend a few moments analyzing.

When it has completed analyzing, Windows will give you a list of areas where it has found files to cleanup. To clean an area, check the box next to it. To leave something intact, such as Temporary files, just remove the check mark next to the item and click OK.

Your computer will then begin the removal process which can take a good while.

DISK DEFRAGMENTATION

When Windows stores programs and files on your hard disk it saves fragments of files in the nearest empty spaces and then links these pieces together. When the computer needs to retrieve a file, it has to go through the process of chasing these links hunting down the fragments and piecing the file back together. This can really slow down a computer, especially if it has small internal memory and has to do a lot of caching and file swapping.

The cure is to routinely run the Windows Disk Defragmenter which gathers together the fragments of files and puts them back in the right order in as near contiguous space as possible.

This makes it far easier for your computer to find what it's looking for on the hard drive, enabling programs and files to load more quickly.

To defragment your hard disk click Start, All Programs, Accessories, System Tools and then Disk Defragment. When the program has loaded, click Defragment. Before starting you need to run "scandisk" which checks for disk errors. Without scanning your disk first for possible errors, defrag may refuse to continue its defragmentation routine.

The process can take over an hour. Because defragmenting your hard disk takes such a long time, you really don't want to go through the process very often; maybe every 3-4 months and it's best not to use the computer while defragmenting

GET A HIGH SPEED INTERNET CONNECTION If you spend a lot of time on the internet, a high speed internet connection is a must. It is more expensive, but for most people the savings in time and effort is worth the added expense.

Some of the advantages to having a high speed internet connection: faster surfing, web pages open more quickly, files download faster, and if you send or receive large files, like pictures or video, they will open in a flash when compared to a slower dialup connection.

If you're already spending money for your dialup connection (through your phone line) then you'll find DSL to be comparable in price, and a lot faster.

A cable internet connection might cost a little more, but it is usually the fastest type of internet connection you can get from home.

REMOVE SPYWARE & ADWARE

If you've ever had spyware or adware on your computer, you know how frustrating it can be. All kinds of strange things happen: your homepage changes seemingly on its own, unwanted and inappropriate popups, unfamiliar icons, and the list goes on.

Spyware or Adware are files that are often downloaded onto your computer without your knowledge (or at least without you knowing what they really are).

Unfortunately, many of these programs "sneak" their way onto your computer, and avoiding them entirely is difficult, especially if you spend a lot of time on your computer, surfing the Internet and downloading new programs and files.

There are ways to remove these unwanted files from your computer.

Check out these 2 adware/spyware removal programs that are simple to use (both are free):

Ad-Aware http://www.lavasoftusa.com/support/download/ Spybot http://www.safer-networking.org/en/download/index.html

Adware/Spyware continue to be such a problem because most of these programs make money for the people creating and spreading them. If you find these unwanted intruders on your computer, don't panic. In most cases, it is not vicious like a Virus or Worm. You just have some extra "junk" on your computer. However, keeping it off of your computer will help it perform more efficiently.

ADD MORE INTERNAL MEMORY (RAM) AND A LARGER HARD DRIVE

If you have done all/most of the above and your Computer's performance is still so bad that you are thinking: Gee, I guess I am going to have to buy another computer! If everything else about the computer is satisfactory to you, then you might consider an Upgrade. If the PC is only a couple years old, it can easily be upgraded.

If you still have the manuals that came with it, you can determine the type of memory it uses and buy it off of the internet at a good price. If you don't have the manuals, take it to Best Buy or Circuit City and ask them if it can be upgraded (or take the model and make info to them). Their upgrade cost is not that bad and certainly cheaper than buying a new computer.

Another alternative: if you know a High School Kid who has taken some computer courses, he/she can probably do it real cheap.

I have personally maxed out my computers memory and added another hard drive. Together with the items above, my computer runs like a "Tiger chasing a Scared Bunny".

I hope this has been of help to you. I have prepared a brief video which depicts the frustration I was having with my computers performance and how I Cured My Computers Performance Problems. You can see it by clicking the link below.

Buy Computer Monitor

Buying a computer monitor is becoming more common these days as everyone is upgrading the latest flat screen models, new systems tend to all have these flat screen models attached with them now so the chances are that flat screens will be the industry standard in the future.

Flat screen monitors are becoming the standard because of the features they bring compared to the older CRT models which are heavier and take up more desk space, CRT models also suffer from screen glare which sometimes make them harder to see in a room with lots of natural sun light.

The newer flat screen TFT monitors bring sharper images to the display and also combats screen glare more effectively, they are ideally suited for the office environment as they are light and take up less desk space which means they are more portable and easier to move around such you need to reposition your computer system.

CRT monitors should quickly become obsolete as the prices of TFT monitors drop and become more affordable or perhaps even cheaper than their CRT monitor counterparts.

Another thing to take into consideration when purchasing a computer monitor is the size of the display, many people opt for smaller displays only to find out that it strains there eyes, sometimes people buy large 21 inch displays only to find out that it doesn’t fit in the space they outlined for their monitor to go, its always best to research your needs before you go to a store or website and make your purchase.

Fix Blue Screen of Death Error

For non techy people that need a solution because they have a "Blue Screen Error" crash that happens whenever you do the following:

1) Loading Microsoft Applications

2) Playing Games

3) Using a Tally software

4) You moved your mouse

This error that you have is the Blue Screen of Death aka BSOD, where the computer screen turns blue, and asks if you have installed any new hardware or software and informs that you need to reboot your computer to fix this error. Here are a few things that can help you fix the blue screen error.

1)Registry Cleaner software

I prefer to use software and fix any errors before deciding what else to do. Reason for this is that going into hardware is little difficult. Opening up the case, changing ram etc. Sometimes when we install multiple programs or delete programs, this can cause the computer to run very slow. The software runs a scan on your harddisk and clears out errors that are giving your problems.

2) Change the Ram Changing Ram is little inconvenient. You'll need to check it the rams at fault. If its a DIY computer and you have 2 sticks of RAM, remove one and see if the problem comes back. Or download Ram checking software to test if the ram is faulty. If you're using Dell or HP, they should have tech support and their own software inbuilt to test the RAM functionality. So just call them for help.

3) In rare cases, both the above don't solve the Blue Screen problem, then the problem could like with the power supply.

If that's the case, then you'll need to backup important data into a thumbdrive and send your PC for repair. The Blue Screen error will not go away on its own and it will come back to haunt you when you did not save that Microsoft Excel File you had spent 2 hrs working on.

External Hard Drive Data Recovery - Not So Different

Internal hard drives. External hard drives. Floppies. CDs. DVDs. They are all great for storing data--until they fail. Nothing is certain in life, and there is no certainty that the means by which you have been storing your important data will not become damaged and require data recovery. You may even be the cause of your lost data, by doing some accidental deleting.

If the data which you are trying to retrieve is stored on an external hard drive, however, the recovery process and can range from simple to highly complicated. But external hard drive data recovery, for the most part, is similar to that used for retrieving lost files no matter where they were originally stored.

Doing Your Own External Hard Drive Data Recovery

If your external hard drive is part of a company network, you will have to attach it to a monitoring system so you can track the progress of t the external hard drive data recovery. Any idle desktop computer or workstation will suffice; you just need to make sure someone is watch dogging the process and can intervene if any glitches occur in the retrieval effort. The last thing you want to have happen is for the external hard drive data recovery process to appear to have finished, and then find that it is still malfunctioning and requires a do-over.

Once the external hard drive data recovery process retrieval is finished, the recovered data will need to be tested for functionality. Begin by checking the operational system files, because without them you will not get far. If they check out, you can go ahead and test the informational files like your business invoices, tax records, spread sheets and databases.

If your general business files are in order, you can branch out and see if the external hard drive data recovery has restored the files with which your company’s different departments work. If all those files are up and running, you can rest assured that the external hard drive recovery went as planned, and you can remove the hard drive from the monitoring station and put it back where it normally belongs.

You can accomplish this by checking various operational and data files that are saved on the external drive. Start out with the operations system first, then move on to some of the larger and more important files, such as your invoicing system. From there you can get into other files that are used fairly often by various persons and departments in your company. Once you are assured that the data is intact, accessible, and working properly, you will know that the recovery was successful and you can return the external drive to its usual station.

When Your Effort Fails

If, however, your efforts at an in-house external had drive data recovery fail, the next step is to take or ship the hard drive to a data recovery specialist. The specialist will examine and evaluate the damage your external hard dive and let you know how much it will cost to perform an external hard drive data recovery, and what you can realistically expect to recover. If your company’s management approves the expense, the specialist will proceed with the recovery attempt and return as much of your data as possible.

Must know facts about toner cartridges

Nowadays virtually, every kind of printer from laser printers to inkjet printers is incredibly inexpensive. Fortunately, the toner cartridges that replace the starter cartridges the come with the printer provide a cost-effective solution. There are great deals online if you are in the market for an inkjet printer cartridge or a laser jet toner cartridge. Laser printer toner called as ‘laser printer toner cartridge’ is a dry powder that is electrically charged during the process to transfer onto the paper to complete the printing procedure. Generally, this toner comes in a cartridge inserted in the printer. This single cartridge can be used for printing multiple pages. Replacing or refilling the empty cartridge is an easy process. Replacing a cartridge offers two advantages: portability and speed.

Toner is used in photocopiers and laser printers to structure the images and text on available printed-paper. Previously it was made of carbon powder. Then carbon was combined with polymer to develop the excellence of the printout. The heat of the fuser result melts toner cartridges elements to attach to the paper. The exact polymer used could be a Styrene Acryl ate Copolymer or a Polyester Resin, but it differs accordingly with the producer. Toner cartridges formulations vary from manufacturer to manufacturer and even from one machine to another machine. These formulae differ from each other in the grain size and melt point. To get a best print, some toner companies use a chemical process to grow toner particles. This results in size in more and more consistent shapes of cartridges particles. This lesser uniform shapes allow more accurate color reproduction and well-organized toner use.

Laser printer toners are classified into four categories in the market. First comes the toner cartridges processed by manufacturer under their brand name. These are called OEM, Original Equipment Manufacturer for example, Epson OEM, Canon OEM, HP OEM, and Brother OEM. Compatible or Generic toner cartridges are the second type which are produced to excel or equal the OEM cartridges. They are less expensive than OEM cartridges. The third one comprises the Remanufactured or Refurbished toner cartridge, which are recycled from the OEMs. Finally, the last type is the Refill Kits that is the most economical method to replace the toner cartridge.

Using toner cartridges against the laser cartridges is beneficiary. The laser printer toners are able to print thousands of pages, and are less expensive per page compared to inkjet cartridges. The printing speed is faster than inkjet cartridges while they almost work on every type of paper. In due course, they prove to be much economical if a lot of printing work is involved. A compatible cartridge benefits you with cost savings and at times massive savings up to 50%. It all depends upon your requirements to utilize these toner cartridges to enhance your printing.

Troubleshoot Windows with Task Manager

Task Manager is a Windows system utility that displays the
tasks or processes currently running on your computer. To
open Task Manager, press Ctrl+Alt+Del. The Applcations tab
lists the applications currently running on your computer.
A single application may actually consist of several running
processes, and many programs that run in the background are
not listed (you can see icons for some of these programs in
the System Tray).

Note: With Windows 98 and Windows Me, Ctrl+Alt+Del will
open Program Manager, which allows you only to close
aplications. However, you can download one of the many Task
Manager utilities from the Web.

The Processes tab displays a comprehensive list of all the
processes currently running on your computer. This can be
very useful for monitoring your system. The process tab
displays information about the processor useage and memory
usage of each process. The problem is, how to identify a
process. Below is a list of some processes you may see in
Task Managers Processes list.

"System Idle Process"
"System" The Windows System Process
"SMSS.EXE" Session Manager Subsystem
"CSRSS.EXE" Client Server Runtime Subsystem
"WinLOGON.EXE" The Windows Logon process
"SERVICES.EXE" Services Control Manager
"LSASS.EXE" Local Security Authentication Server Service
"svchost.exe" Service Host
"spoolsv.exe" The print spooler service
"explorer.exe" Windows Explorer
"TASKMGR.EXE" The Task Manager
"regsvc.exe" Remote Registry Service


"System Idle Process" is basically another name for the
time when Windows is doing nothing. There are hundreds of
thousands of processes that run on a computer, so you will
definitely find names of many other processess that are
not listed above. For a list of well known processes,
visit www.answersthatwork.com/Tasklist_pages/tasklist.htm
You can also learn about almost any task by using it's
name as a search term in google.

Task Manager can also be used to tweak your system if it's
running slow. The Performance tab displays running graphs
of your computers CPU and memory usage. If the CPU usage
seems to be running over 80 percent most of the time, or if
the memory usage seems to be running higher than the total
physical memory, you may want to shut down some
applications or processes.

On the Process tab, you can identify processes that are
consuming a lot of processor time. Click twice on the CPU
column heading to sort the CPU column so the processes
hogging the most CPU time on top. You can sort the
"Mem Usage" column the same way.

On the Application tab, if you right click on the name of
an application and, in the popup menu that appears, choose
"Go To Process", Task Manager will open the Processes tab
and highlight the process that runs the application. On the
Processes tab, if you right-click on the name of a process,
you can choose "SetPriority" and promote the priority of
the process you need (or demote the priority of a different
process to free up some resources).

If you go to the Application tab and shut down an
application, you will shut down any processes related to
that application. Or, you might choose to shut down a
background process that you can identify. To shut down an
application or process, click on it's name in the list to
highlight it, then click on the End Task button.

On the Processes tab, if you right click on the name of a
process, you can choose "End Process Tree" to kill the
process and any sub-processes started by the process.

Task Manager can also be used for troubleshooting. If an
application freezes up, you can open Task Manager and shut
down the application. If the entire system freezes up, you
can use Task Manager to shut down a process that is hogging
all the CPU time or memory.

If you spend some time monitoring your computer with task
Manager, eventually you will become familiar with the
processes that commonly run. Then, when you see an
unfamiliar process, you can do a little investigation to
make sure it's not a virus. For example, if you see
msblast.exe in the process list, your computer is infected
with the Blaster virus. You might be able to detect and
eliminate a new virus before an antivirus update is available.

Passwords Used In Microsoft Word Documents

You would like to protect your documents, wouldn't you? Reasons may vary but the problem is the same – you need to protect your Microsoft Word documents from unauthorized editing or viewing. What document protection features does Microsoft® Office Word 2003, a part of Microsoft Office Professional Edition 2003 provide?

Microsoft Word features for document protection. Microsoft Word offers three types of password protection.

1) Password to open requires a password to open a document. By assigning a password to open a document you deny access to this document to anyone who doesn't know the password.

You may assign a password to open both a new document (Save As > Tools > Security Options) and an existing one (Main Menu > Tools > Options > Security).

2) Password to modify requires password to save currently made changes. Password to modify allows every user to view and to edit a document (with a special read-only setting) but not to save these changes. Only an authorized user is allowed to save changes. Please note that by opening a document as read-only and copying it to a new document with a clipboard it is possible to obtain an unprotected copy of your document.

This password is set the same way and in the same window as password to open.

3) Protect Document – document protection. With this type of protection you prevent your document from any alterations. Any user can freely view it but no one is allowed to edit, copy, or format it. To a certain point it is similar to a pdf file viewed with Adobe Acrobat Reader.

It is possible to set or delete this type of protection with : Tools > Protect Document or Unprotect Document; select exclusions and apply protection.

These are the main features provided by Microsoft Word 2003. It is nice when everything is working fine but what happens if somebody cracks your protection by guessing your password? And what are you going to do if you lose or forget the password for your document? How powerful and reliable is Microsoft Word 2003 protection?

When assigning a password the program warns you not to lose it as you can't recover the password. This is not exactly right. Any password can be cracked. The point is how much time it will take for special program to crack your password. For instance, Protect Document password uses a rather easy protection method and a few seconds is enough to recover this kind of password. It is similar with Password to modify. But it is not that easy with Password to open:

The first versions of Microsoft Word had rather weak security; it took a bit more time to crack it compared to the other types used in Microsoft Word. But starting from Microsoft Word 97 version the situation has been improving. The new version had more cryptoproof security; it would take many years to crack it with the brute-force and PIV computer. Please note that it doesn't apply to Microsoft Word 97 version supplied to the French market as these versions had the old protection from the previous Microsoft Office 95. Cryptoprotection options were further advanced in Microsoft Office XP (realization in Office 2003 is the same). At the moment, the user can chose encryption mode to protect his documents.

This option is customized by assigning password to open (Advanced... button). In the window you will see a list of possible algorithms of document protection. Almost all of them are hard nuts for a hacker; it would take him a long time to crack your document. For more detailed information on password recovery see the article on our resource

How to Backup Windows XP Home Edition

Your computer cost you from hundreds to thousands of dollars, but the computer itself is not the most valuable part. The data on the hard disk is the most valuable part. How many hours of work did you put into creating that data? One little event, like a power line spike from a lightning strike, and all that work could be lost. Unfortunately, backing up with Windows XP Home Edition is not as simple as it should be.

The first step is to choose a backup device. You might choose a tape drive or a DVD drive, but those devices might require drivers to be installed before you could restore from them. The simplest option is to install a second hard drive in your computer.

The second hard drive doesn't have to be equal to your main hard drive. You can use an older, smaller hard drive as the backup device, as long as the backup drive has more "Free Space" than the main hard drive has "Used Space".

Install a Second Hard Drive

When installing a second hard drive in your computer, it's important to configure the drives correctly. Your motherboard should have two ATA (sometimes called IDE) connectors. The primary connector should have a cable with two drive connectors. The end connector should go to your main hard drive, the middle connector can be used for a backup hard drive. The second motherboard ATA connector should go to your CD-ROM.

On the back of each hard drive is a jumper. The jumper on your main hard drive should be set to the "Master" position. The jumper on your backup hard drive should be set to "Slave" position. Most modern computers use "Cable Select", so you can set both jumpers to the "Cable Select" position. Don't forget the power connector for the second drive.

When you restart your computer, the second drive should be automatically recognized and be designated with the next drive letter available, usually E: (D: being used for the CD-ROM drive).

Format the Second Hard Drive

Generally, you will want to re-format the second hard drive after installation to remove any previously installed operating system and to remove any previous file access rights. To format the drive, select Start | Settings | Control Panel | Administration Tools | Computer Management. In the "Computer Management" window, under "Storage", click on "Disk Management".

Right click on the backup disk's drive letter. In the popup menu, select All Tasks | Format... In the Warning dialog box that appears, click on the "Yes" button. In the "Format" dialog box, in the "File system" drop-down list, select NTFS. Click on the "OK" button. Again, in the Warning dialog box that appears, click on the "Yes" button.

Install the Backup Utility

Windows XP Home Edition doesn't install the Backup utility by default. You'll need to install it manually from your Windows XP CD-ROM.

1. After inserting the CD-ROM, open Control Panel's "Add or Remove Programs" utility. In the "Add or Remove Programs" utility", click on the "Add New Programs" button, then click on the "CD or Floppy" button.

2. In the "Run Installation Program" dialog box that appears, navigate to the VALUEAD/MSFT/NTBACKUP folder on the CD-ROM and select the file NTBACKUP.MSI. Click on the "Finish" button. The Backup utility will be installed.

Perform a Full Backup

To perform a backup, select Start | Programs | Accessories | System Tools | Backup to open the Backup Utility.

Note: If you don't find Backup listed in System Tools, double click on the file name ntbackup.exe in the Windows\system32 folder.

In the "Backup or Restore Wizard", click on the "Advanced Mode" link. In the "Backup Utility" dialog box, select the "Backup" tab and set the checkbox next to the drive to backup (c:) and set the checkbox next to "System State".

In the "Backup media or file name" text box, enter the path to the file for the backup (example E:\Backup.bkf). Click on the "Start Backup" button.

In the "Backup Job Information" dialog box that appears, set the radio button next to "Replace the data on the media with this backup". Click on the "Start Backup" button. The "backup Progress" dialog box will appear.

Even when you backup to relatively fast media like hard disk, the process can take 30 minutes or longer depending upon how much data is on the main drive.

When the backup is complete, turn off the computer and remove the data and power cables from the backup drive. It doesn't make sense to leave the backup drive connected because if the cause of a failure is a power spike, it will take out both drives. Next time you want to backup you'll need to reinstall the cables.

How to Perform a Restore

In the unfortunate event that your computer crashes and you can't get it back by any other means, you'll need to reinstall Windows XP from the CD-ROM. (Automated System Recovery is not supported in Windows XP Home Edition.) You'll need to re-install the Backup utility. Then you'll need to shut down the computer to install the data and power cables to the backup drive. Restart the computer and use the Backup Utility to restore Windows XP from the backup file.

When using this backup method, it's important to be careful not to break any pins when you are removing and installing the data cable of the hard drive. And if your computer doesn't use "cable Select", don't forget to change the jumper on the main hard drive back to "Single".

How To Get Out of the Microsoft Habit

In our country, we have become so addicted to Microsoft that we cannot seem to do without it. It has become like morphine: we get off it, we feel pain so great, we writhe in sheer agony.

Don't get me wrong. I am a BIG fan of Microsoft Word and Microsoft Encarta. But the OS's? Oh, don't ever get me started!

From the moment I saw Ubuntu Linux, I was... Stunned to say the least. I always thought that Linux OS's were... Primitive. Turns out, it just got bad press.

Though I thoroughly enjoyed Ubuntu, I had to delete my Ubuntu drive after about a month or two of using it when I needed the space for my other files. And the parting wasn't easy. Though I loved Ubuntu Edgy Eft like crazy, I wasn't ready to be weaned off Windows yet. I thought I “needed” Windows. Yeah right. Like a hole in the head.

The decision to fully migrate my desktop to Ubuntu or any other reliable Linux distro came when my Windows XP melted down. I decided I was finally ready to move permanently... When I discovered Wine. But more on that later. This is an article on how to choose a different OS. :p

The mainstream Operating Systems for desktops for the everyday user come in two major branches. I know, I know, there are other OS's out there, but for the moment, I'll just talk about the most well-known, most user-friendly “Windows alternatives”.

How to choose the OS for you

Choosing is a universal function of needs, desires, and availability, among other factors. There is no one way to go about it, and sadly, it is not a science. but I have made a system for myself on how I can go about my own choices. I hope my system would help you. Below are the steps on how I go about making Operating System choices.

Know what you need.

Knowing what you need need not be a precursor to lobotomy. Just grab a notepad and the guidelines and questions below may help you:

What is it that you do?

Are you a graphic artist? A web designer? A writer? A student? A casual user?

Base your choices on what you do, because your needs will depend on this.

What software needs to be on your computer?

If you are a graphic artist or a web designer, you would definitely need tools like Adobe Photoshop. If you cannot afford the price, there are alternatives like the Gimp on Linux. However, I have a friend who says that he can never work on Linux, though he's not a Microsoft loyalist. According to him, Adobe Photoshop doesn't look as good on Linux as it does on Microsoft Windows. BUT, there is Adobe Photoshop for Mac, and it actually looks light years better than on Windows. Why? Mac screens are just rich, with the million-color support. If you have the money to burn, and you need apps like Adobe Photoshop and even Dreamweaver, then you better get OS X. Or else, get yourself a Macbook/Macbook Pro/iMac. Now. :p

As for the writer, since word processing is light, and doesn't really require as much RAM as applications like Adobe Photoshop or Dreamweaver, which, in turn, require support for high resolution, I guess it would be safe for me to recommend that you use Linux. There are excellent applications to replace MS Office, like Open Office, Star Office, etc. AbiWord is an excellent MS Word replacement. It's light, fast, and simple. And you can write in pure white space, if you're allergic to distractions. These applications can save in the MS Word .doc format. But if you just have to have the MS Word formatting for your work, then by all means, go for Ubuntu Linux's Feisty Fawn! It has Wine built into the system. Wine is the application that can run your MS programs, and it's really an excellent tool to wean you off the Microsoft addiction. Though I have yet to try out Wine on Linux, as I am waiting for the official release of Feisty Fawn on April 19, I have tried Crossover, a non-free distro of Wine, on my OS X. It was able to run MS Office seamlessly so far. It's not slow when it's up and running, and though the fonts are just smaller, the main point is, it's running the Microsoft program. Enough said. I'm planning to pay for my copy when the trial expires.

Students, on the other hand, have varied needs. I recommend Linux if you're not into heavy photo editing anyway, as:

  • It's free.
  • If you want games, Wine can run World of Warcraft for you. Yes it does. Games are the priority of the Wine community!
  • Linux helps sharpen your skills, if you're a Computer Science or Information Technology student.
  • It's free.
If you are a casual user with money to burn, then you could definitely work well with OS X! OS X, according to my friend, is better for the dummy user than Windows! Why, I am a very destructive dummy user. I actually install anything I fancy. I have installed some pretty serious stuff here in my Macbook, decided I didn't want them anymore, couldn't find the documentation for how to uninstall the stuff I did, and decided, “What the hell, I'll just toss all the programs in the trash”. The only thing I noticed that was different right after was that the fonts in iTunes got messed up a little. :D But after installing an update on everything including the system, that problem was fixed. :D Oopsie. :D

But if you're like me, a total cheapskate, I believe that you would do well on Ubuntu or PCLinuxOS. Both are very user friendly, and I was blown away by the two Operating Systems. As soon as I get a stack of CD's, I'm trying out the other user-friendly Linux OS's, and I'm going to feature them here. Meanwhile, why don't you check out these OS's themselves, and see for yourself that they really are nice. :) Go to http://www.distrowatch.org or http://www.ubuntuforums.org to see what people think about the different OS's, and which are the popular favorites. :)

What are the primary features that you would want on your operating system?

You would do well to make a list of what you want as features on your OS. Below is my own list:

--User-friendliness
--Easy to install built-in applications
--Package manager/handler for easy installation
--Applications that are good equivalents for Windows applications
--Easy networking setup
--Compatibility with Wine or any other Windows emulator
--Can read Fat32 (hard drive format) for easy Windows sharing
--Customizable User Interface
--Installable Windows/Apple media codecs
--Easy install of Java and other media support
--Fast loading/non RAM hog
--The OS does not “hang,” restart randomly, or crashes. If it does, it should be rare, or like in Ubuntu, will only prompt that it has crashed, but will not affect the operation of the system or its applications.
--The OS should have a very helpful support community.

So far, Ubuntu Linux is my best choice. It is the best in application installation, has a really wide range of built-in apps, and with each release in its 6-month cycle, it gets increasingly user-friendly, and is getting more packed in features as the days go by. Ubuntu Feisty Fawn comes with a Windows networking setup manager, so it will be easier to manage your local network/s. It also comes with Wine, so you don't need to really rack your brain with how to install this (non) emulator. The only thing that's annoying with Ubuntu is that it takes long in starting up.

If you want a faster OS, you can try PCLinuxOS. I have yet to install it, so I don't know about its application manager: if it's easy to deal with or not. But it's highly user-friendly according to forums, and as I've used it through its live CD. And it's eye candy, too. :)

Ubuntu can also become eye candy if you install themes and change the desktop background. If you find the pre-installed brown theme yucky, change it! The options are shown when you right click on the desktop, the panels, and if you go to system>themes. Mine is delicious pink. Heehee. :D

Another thing that is great in Ubuntu is the kick-ass community. According to some people I read there, PCLinuxOS has a great community, too, as according to people I've read on Ubuntu's forums. It's actually better, according to them, as the programmers/developers themselves entertain questions on PCLinuxOS.

If your hardware cannot support heavy programs, there are “thin clients” out there, which can be run even on a decade-old machine. If your machine used to support Windows 95 and is still wired for 95, you can go for OS's like Xubuntu or Puppy.

Research on your options.

If only I didn't need to work, I would rather be on the forums all day and clicking away at Linux sites. So far, the best Linux distros as far as I've learned are Ubuntu, PCLinuxOS, Sabayon, Arch, Mint (Ubuntu based), Puppy Linux, Mepis, Xandro's and Knoppix, to name a few. Knoppix and Puppy can be installed on removable media, and you can save your files there, especially if it's a multisession/rewritable disk or flash drive.

Again, do try to frequent the forums, you will sure learn a lot there.

Test the top three to five on your option list.

I do not like to wade through the hundreds of Linux distros, only to find them to be lousy. I would rather know about the best few then test them. It's a good thing that most Linux OS's come in Live CD's, so you can run them without having to install them. I suggest you try Ubuntu, PCLinuxOS, Xandro's and Puppy. They are the most user-friendly around, according to most people. PCLinuxOS and Puppy are very fast. If you really like Ubuntu and just want it to run faster, as I've said, you can go for Xubuntu. Take heart, there is an OS out there for you. Or else, you can compile one from Linux's source code. Hrhr. :p

As for OS X, I cannot say more. It is really an excellent Operating System. It has the stability of Linux, being also a Unix-based OS, and it is far more user-friendly than Windows. No, you do not need to have an Apple machine to run it. People have been able to run it on X86 machines successfully. Just read the how-to's on the Internet.

OS X is really eye candy, and they have “dumbed down” the controls on a lot of the programs, to increase user-friendliness. Yes, there are moments when I feel that some Mac programs (especially the iLife programs) are too simple for my taste, but I really don't want to complain, as they do the job, and they do it excellently. Where else can you install programs by just dragging the icon to the Applications folder? If that isn't idiot-friendly, what is?! :D

As I said, choosing an OS need not be brain lobotomy. Just explore, research, and have a system in making choices. You need not suffer on a system that melts down with every trojan and spyware outbreak. You can be free. You can migrate. Screw Microsoft. Screw Vista. Go for Open Source (or Apple :p).

Motherboard Basics

A recent Tech Tip covered the basics of selecting a computer case and made mention of the various sizes that correspond to motherboards of different form factors. A few people wrote in expressing interest in understanding more about the basics of motherboards, and that’s exactly what this Tech Tip intends to address.

A motherboard, also known as a main board, is the primary circuit board inside of a computer, and is where the central processing unit (CPU), memory, expansion slots, drives, and other peripheral devices are connected. The circuitry on a motherboard facilitates the communication between all of the devices in the computer, making them as critical to a system’s performance as items such as the CPU or memory.

The core circuitry of a motherboard is referred to as its chipset, and generally the manufacturer of the motherboard is not the manufacturer of the chipset. Intel does produce motherboards with their own chipsets, but buying a motherboard brand such as Gigabyte, Biostar, and ASUS means getting a board with either a VIA, Nvidia, SIS, or Intel brand chipset.

1. Form Factor

The different basic shapes and sizes of motherboards are categorized as form factors. There are several standard form factors available, but some of the more common ones found in desktop computers include: (http://www.formfactors.org/developer/specs/atx2_2.pdf), ATX (http://www.formfactors.org/developer/specs/matxspe1.2.pdf), Micro ATX (mATX) (http://www.formfactors.org/developer/specs/FlexATXaddn1_0.pdf) FlexATX (http://www.via.com.tw/en/initiatives/spearhead/mini-itx/) and Mini-ITX

The basic sizes of each are as follows:

* ATX: 12" x 9.6" (305mm x 244mm)

* Micro ATX: 9.6" x 9.6" (244mm x 244mm)

* FlexATX: 9.0" x 7.5" (229mm x 191mm)

* Mini ITX: 6.7" x 6.7" (170mm x 170mm)

ATX and mATX are by far the most popular motherboard sizes for desktop computers, and as seen in the list above, are also some of the largest. More real estate on a motherboard allows for greater expansion possibilities and extra features, which make the use of these boards more flexible. A Mini-ITX board may feature just one slot for memory and one slot for an expansion card, while a typical ATX board may feature 4 memory slots and six slots for expansion cards.

Each form factor has its own niche that it fits into, from workstations and gaming systems for larger boards to media centers and in-car computers for smaller boards. There is definitely overlap between the potential applications of each form factor, and other features and capabilities will also influence the targeted use.

2. CPU Socket

The major processor manufacturers, AMD and Intel, are constantly waging a battle to offer the fastest, most powerful processors available. Getting more speed and performance out of a relatively small chip generally requires a change to the physical dimensions as each new generation of processor is released. Therefore, motherboards need to evolve at the same pace in order to accept the new CPUs.

Back in the day, AMD and Intel processors shared a common CPU socket, but those days were short lived. AMD and Intel have since been traveling down their own, relatively parallel, paths of performance and speed increases, while using different designs. Selecting a motherboard for a modern AMD processor eliminates the use of any Intel processor, and vice versa.

AMD’s current offering for desktop processors includes the Athlon 64, which is available in Socket 939 and Socket 754 formats. The number in the names represents the number of pins present on the backside of the CPU that connect to the motherboard’s socket. The Socket 939 Athlon 64 therefore has a staggering array of nine hundred and thirty nine tiny pins to match up with the motherboard’s socket. The Chaintech VNF4 Ultra is an example of a Socket 939 motherboard based on Nvidia’s NForce4 Ultra chipset technology. In addition to these two sockets, many AMD processors, including Athlon XPs, Semprons, and Durons, share the Socket A format, also known as Socket 462 thanks to it having 462 pins for connecting to a motherboard.Socket adapters

Intel’s latest offering for their Pentium 4 and Celeron processors, LGA 775, doesn’t have pins at all and basically swaps the pins to the motherboard for the socket. Perhaps this design move puts the burden of bent pin warranty claims on someone else, but it is fairly unique. The Biostar P4M80-M7 is an example of an LGA 775 motherboard based on the VIA P4M800 chipset. Other Intel processors still on the market utilize the Socket 478 format for Pentium 4 and Celeron processors.

Although most motherboards support just one CPU socket, some applications benefit from having more than one processor to tackle the tasks at hand. Servers and high end workstations are two examples where a dual processor system, such as could be run on the Tyan Thunder i7500 motherboard, might make light work of more advanced applications.

3. Components

‘Components’ is a fairly vague term to describe this section, but the items to be covered are fairly diverse. Computer systems all use memory, storage devices, and power supplies, but among the many differences motherboards have is the type and quantity of connections for these components.

Most modern systems use DDR memory, but DDR-2 memory is becoming more common and will eventually become the standard. Although some boards provide slots for both types of memory, it is generally the case that either one or the other technology is supported. Besides operating differently, the physical difference of DDR having 184 pins and DDR-2 having 240 pins prevents them from being interchangeable. Going forward, users will have to decide whether they want to jump on the new technology bandwagon when selecting a motherboard, or to try to continue using their existing DDR for as long as possible. Regardless of technology, most motherboards come with 2 to 4 slots for memory, although as mentioned, Mini-ITX boards may just offer 1 slot.

Hard drive technology is changing too, as mentioned in the Tech Tip comparing SATA to ATA hard drives. Most motherboards over the past few years have offered two ATA connections, which could support up to 4 drives. With SATA becoming more popular, some boards now offer a mix of ATA and SATA connections, while others have abandoned ATA all together, and instead offer multiple SATA connections which only support one drive each. In addition to type and quantity, motherboards can also offer choices in hard drive capabilities by integrating RAID controllers onboard, as found on the ASUS K8V SE Deluxe.

As systems become more advanced, they many times impose special power requirements to keep them running smoothly. Most motherboards feature the typical 20 pin ATX power connector, while some server boards may have a 24 pin connection in its place. Motherboards for AMD Athlon 64 and Pentium 4 processors will have a second power connection located in close proximity to the CPU socket for providing the extra power that today’s high end processors demand. This special 4 pin connection isn’t found on every AMD Socket A motherboard, but it will most definitely be located on an AMD Socket 939 motherboard. Power supplies have been including this special connection for years, but for those upgrading an old system with a new motherboard, the power supply may be just one more item that has to be upgraded as well.

4. Extra Features

Many motherboards now include features onboard that were once only available as expansion cards to be purchased separately. A typical motherboard will now include stereo sound capabilities, a 10/100 LAN connection, and a few USB 2.0 ports on the back panel connection. Depending on the budget and needs of the end user, many motherboards may also include other convenient features such as integrated Firewire ports, VGA connections, and onboard RAID controllers.

Motherboards Extra Features

Although many of these items may be added later with expansion cards, if you know you want them upfront, a bit of installation hassle and expense can be eliminated by finding a board with just about everything you want included. That said, there aren’t many choices of onboard components, so it’s a case of take it or leave it. For example, you may want stereo sound included, but find most motherboards offer 5 channel, where you would prefer 8 channel. In that case, it may be a good thing that motherboards include expansion slots to add the sound card of your choice.

5. Expansion Slots

A motherboard typically provides at least one slot for the installation of a graphics card and a few slots for expanding the capabilities of the system in other areas.

Graphics cards are available in PCI, AGP, and now PCI Express formats, and matching a motherboard to the appropriate card is a key step. Most motherboards released over the past few years include an AGP slot, and the new wave of motherboards are now starting to feature PCI Express slots for graphics card installation.

PCI slots are found on most motherboards, but are much slower than AGP and PCI Express slots, so they are not the optimal choice for graphics. ATX motherboards may typically feature four to five PCI slots, and although they could be used for secondary display graphics cards, more common applications include sound cards, network cards, RAID controllers, TV tuners, modems, and USB/Firewire controllers. Considering that many of these items are now included onboard, having multiple PCI slots isn’t quite as important as it used to be.

6. Style

With enthusiasts adding windows and special lighting effects to just about every feature of a computer, why should the motherboard be left out of the action? Long gone are the days of the stereotypical green PCB with white connectors, and now most boards feature a vibrantly colored PCB and a rainbow of colors on expansion slots, memory slots, drive connectors, and so on.

For example, if someone was undecided on a mATX board for their Socket 754 AMD Athlon 64, style might be the deciding factor. The Chaintech MK8M800 and the Biostar K8VGA-M-N are similar boards featuring the VIA K8M800 chipset and prices under $70. The golden PCB with black and white features of the Chaintech board may appeal to some, while the red, white, blue, and yellow of the Biostar may sway others.

In general, a particular model is only available in one color scheme, and many manufacturers use the same theme across their entire current line up. As an example, the Biostar board for AMD Athlon 64 processors above features the same basic style as this Biostar board for the new Pentium LGA 775 processors. In addition to coloring, some manufacturers will include LED lighting on chipset cooling fans, or accessorize motherboards with matching cables to complete the unique looks of the board.

Some people may scoff at colors being included in the list of key features on motherboards, but there will be some that shop for style first, and then performance.

Final Words

There are many factors to address in selecting a motherboard, and this Tech Tip really just scratched the surface of the basic choices that may need to be considered. Much more technical decisions may need to be made by the advanced user, but covering the six basic areas discussed above is a good start for users of any level.

Setting Up Your PC for Dual-monitors: It's Easier Than You Think

The traditional view of a "PC"
If you ask just about anybody what their idea of a "PC system" is they will probably list a tower, a keyboard, a mouse and a monitor. While it is true that these are the essential elements of using a personal computer, it is becoming more and more popular to use an alternative setup.

Sometimes two is better than one
It is becoming increasingly more common to see people using two towers with one keyboard, video and monitor. This is accomplished through the use of a KVM switch - as you probably already guessed, KVM standard for keyboard-video-mouse. This is great for people who need more computing power than they can get with one machine. A good example of this would be in a graphic design environment where you are consuming a high percentage of your available RAM and CPU power to run heavy editing applications.

Sometimes you need more room to be productive
For some people computing power is not a huge issue, but they could use more desktop space: enter the dual-screen setup. This allows you to have two monitors that essentially share your desktop. You can drag items from one monitor to another and if you have a long window you want to view, you can sprawl it out across both monitors. This is great when you need to use another screen as a reference or you want a static window that you can always check (with stock symbols, sales figures, etc.).

It's not that hard to do
A lot of people see dual-screen setups and they think that it's hard to do - it's really not. First of all you need a dual-monitor video card. Do not try to use two single-port video cards - you will probably have IRQ conflicts that will keep you from using both at the same time - special software is bundled with all dual-port video cards that allows both ports to peacefully co-exist.

DVI vs. VGA
For some reason most dual-port video cards have one VGA port and one DVI port. I am not saying that dual-port VGA or dual-port DVI cards don't exist, but I have never seen one. This can be kind of a pain because you might have two VGA monitors or two DVI monitors. Don't worry - there is a solution. You can easily find a DVI-to-VGA adapter or a VGA-to-DVI adapter from just about anyone who sells you a video card. Be aware that if you have two DVI monitors that your DVI signal will be downgraded to analog, but the quality loss is almost unnoticable unless you have a huge monitor. Also, using a VGA-to-DVI adapter will not upscale your signal to a digital signal - it will pass an analog signal through the DVI port.

You will need to install included software
Regardless of where you buy the card from there will be some software that you will have to install to get your new setup to work. As I mentioned earlier, this will resolve any IRQ conflicts that would otherwise arise and give you some cool options for your desktop such as specifying which monitor should be the right-side of the desktop and which should be the left.

Be sure to uninstall your old card first
Whether you choose to use an AGP video card or PCI, you should definitely remove your existing video card first (and disable any software related to the old monitor). This will remove the possibility of a driver conflict and make you and the computer much happier in the long-run.

ATA vs SATA

Hard Drives: ATA versus SATA

The performance of computer systems has been steadily increasing as faster processors, memory, and video cards are continuously being developed. The one key component that is often neglected when looking at improving the performance of a computer system is the hard drive. Hard drive manufacturers have been constantly evolving the basic hard drive used in modern computer systems for the last 25 years, and the last few years have seen some exciting developments from faster spindle speeds, larger caches, better reliability, and increased data transmission speeds.

The drive type used most in consumer grade computers is the hearty ATA type drive (commonly called an IDE drive). The ATA standard dates back to 1986 and is based on a 16-bit parallel interface has undergone many evolutions since its introduction to increase the speed and size of the drives that it can support. The latest standard is ATA-7 (first introduced in 2001 by the T13 Technical Committee (the group responsible for the ATA standard)) which supports data transfer rates up to 133MB/sec. This is expected to be the last update for the parallel ATA standard.

As long ago as 2000 it was seen that the parallel ATA standard was maxing out its limitations as to what it could handle. With data rates hitting the 133MB/sec mark on a parallel cable, you are inviting all sorts of problems because of signal timing, EMI (electromagnetic interference) and other data integrity issues; thus industry leaders got together and came up with a new standard known as Serial ATA (SATA). SATA has only been around a few years, but is destined to become “the standard” due to several benefits to be addressed in this Tech Tip.

The two technologies that we will be looking at are: ATA (Advanced Technology Attachment) – a 16-bit parallel interface used for controlling computer drives. Introduced in 1986, it has undergone many evolutions in the last 18+ years, with the latest version being called ATA-7. Wherever an item is referred to as being an ATA device, it is commonly a Parallel ATA device. ATA devices are also commonly called IDE, EIDE, Ultra-ATA, Ultra-DMA, ATAPI, PATA, etc. (each of these acronyms actually do refer to very specific items, but are commonly interchanged) SATA (Serial Advanced Technology Attachment) – a 1-bit serial evolution of the Parallel ATA physical storage interface.

Basic Features & Connections

SATA drives are easy to distinguish from their ATA cousins by the different data and power connections found on the back of the drives. A side-by-side comparison of the two interfaces can be seen in this PDF from Maxtor, and the following covers many of the differences…

Standard ATA drives, such as this 200GB Western Digital model, have somewhat bulky, two inch wide ribbon cable with 40-pin data connections and receive the 5V necessary to power them from the familiar 4-pin connection. The basic data cables for these drives have looked the same for years. A change was made with the introduction of the ATA-5 standard to better improve the signal quality by making an 80 wire cable used on the 40-pin connector (these are commonly called 40-pin/80-wire cables). To improve airflow within the computer system some manufacturers resorted to literally folding over the ribbon cable and taping it into that position. Another recent physical change also came with the advent of rounded cables. The performance of the rounded cables is equal to that of the flat ribbon, but many prefer the improved system air flow afforded, ease of wire management, and cooler appearance that come with them.

SATA drives, such as this 120GB Western Digital model, have a half inch wide, 7 “blade and beam” data connection, which results in a much thinner and easier to manage data cable. These cables take the convenience of the ATA rounded cables to the next level by being even narrower, more flexible and capable of being longer without fear of data loss. SATA cables have a maximum length of 1 meter (39.37 inches), which is much greater than the recommended 18 inch cable for ATA drives. The reduced footprint of SATA data connections frees up space on motherboards, potentially allowing for more convenient layouts and room for more onboard features!

A 15-pin power connection delivers the 250mV of necessary power to SATA drives. 15-pins for a SATA device sounds like it would require a much larger power cable than a 4-pin ATA device, but in reality the two power connectors are just about the same height. For the time being, many SATA drives are also coming with a legacy 4-pin power connector for convenience.

Many modern motherboards, such as this Chaintech motherboard, come with SATA drive connections onboard (many also including the ATA connectors as well for legacy drive compatibility), and new power supplies, such as this Ultra X-Connect, generally feature a few of the necessary 15-pin power connections, making it easy to use these drives on new systems. Older systems can easily be upgraded to support SATA drives by use of adapters, such as this PCI slot SATA controller and this 4-pin to 15-pin SATA power adapter.

Optical drives are also becoming more readily available with SATA connections. Drives such as the Plextor PX-712SA take advantage of the new interface, although the performance will not be any greater than a comparable optical drive with an ATA connection.

Performance

In addition to being more convenient to install and drawing less power, SATA drives have performance benefits that really set them apart from ATA drives.

The most interesting performance feature of SATA is the maximum bandwidth possible. As we have noted, the evolution of ATA drives has seen the data transfer rate reach its maximum at 133 MB/second, where the current SATA standard provides data transfers of up to 150 MB/second. The overall performance increase of SATA over ATA can currently be expected to be up to 5% (according to Seagate), but improvements in SATA technology will surely improve on that.

The future of SATA holds great things for those wanting even more speed, as drives with 300 MB/second transfer rates (SATA II) will be readily available in 2005, and by 2008 speeds of up to 600 MB/second can be expected. Those speeds are incredible, and are hard to imagine at this point.

Another performance benefit found on SATA drives is their built-in hot-swap capabilities. SATA drives can be brought on and offline without shutting down the computer system, providing a serious benefit to those who can’t afford downtime, or who want to move drives in and out of operation quickly. The higher number of wires in the power connection is partially explained by this, as six of the fifteen wires are dedicated to allowing the hot-swap feature.

Price

Comparing ATA drives to SATA drives can be tricky given all of the variables, but in general it is the case that SATA drives will still cost just a bit more than a comparable ATA drive. The gap is closing rapidly though, and as SATA drives gain in popularity and availability a distinct shift in prices can be expected. Considering the benefits of SATA over ATA, the potential difference of a few dollars can easily be justified when considering an upgrade. Computer Geeks currently has a limited selection of SATA drives, but several technical sites, such as The Tech Zone and The Tech Lounge, offer real time price guides to see how comparable drives stack up.

Final Words

The current SATA standard provides significant benefits over ATA in terms of convenience, power consumption and, most importantly, performance. The main thing ATA has going for it right now is history, as it has been the standard for so long that it will not likely disappear any time soon. The future of SATA will be even more interesting as speed increases will help hard drive development keep pace with other key system components.

Notebook For The Casual User

The notebook has a great deal of features, but what you use it for greatly affects the type that you should purchase. The device is designed to be compact, transportable and still provide all the technological requirements that suit your needs. Certain elements affect these notebook features a great deal. Many are unnecessary if you want to use the device only for fun or for occasional use, and others are also essential. It is important that you know what you need so that you can make sure your notebook is a sound investment.

A recreational notebook user wants a device to be able to edit video, play DVDs, access the internet for browse and downloading games. For these requirements an internal CD/DVD will be required. These can be bought as an accessory, but if entertainment is the key requirement then it makes sense to buy one with inbuilt capabilities. This will provide instant access, making the device more readily accessible and less cumbersome for the recreational user. The inbuilt DVD player will make the notebook heavier.

The size of the notebook screen will affect the quality of the entertainment used. A larger screen is required to make the image clearer and more enjoyable. This will make the device bulkier and heavier, but if it used for recreational reasons, then this is seldom a problem. A fifteen to seventeen inch screen is perfect for the recreational user. This also means that the keyboard will be larger which can assist with gaming in terms of better and easier access to controls. The graphics card needs to be able to produce a good quality image on these screens, and so choose a notebook compatible 3d option. If it is inbuilt, check to make sure it is top of the range to avoid disappointment.

Any notebook has built in memory that can easily cope with an excess of word processing and document creation and storage. However, if you are using it for entertainment, then the size of the memory will be important. The bigger the memory; the best quality product you will receive. The memory affects picture quality, game choice, graphics, and game speed. If any of these are a requirement then you should choose a notebook with maximum memory to get the best possible results. If you are using a video card that says `Shared Video Memory` then this means that it uses some memory from your notebook. Small amount of memory also restricts the number of colours available and so again it will produce an image of low quality.

Downloading films and games from the internet require good hard disk space also. Many games are multi faceted and so require regular saving. These store lots of information including graphics, and so try to keep the amount to a minimum to get the best performance from your notebook. Games on disc use less memory, and so combine the use of the two for better variety. Add and remove downloaded films as required to get the best from your device. This is also important for the battery life.

Using a notebook recreationally runs the battery down much more quickly than for business use. The more information stored, the more output is expected, and so the battery will take the strain. Keeping a neat and well organised notebook will ensure you get optimum performance.

Wi-Fi Cameras - The Next Big Thing?

The future is now--almost.”

Imagine a digital camera with the same functionality you get from your camera phone—but with the quality-control functionality that you expect from your regular camera. The future is now—almost.

Wireless digital cameras are arguably the next big thing in the photography world. A marriage between Wi-Fi technology and digital cameras allows the photographer to connect to a wireless network without needing cables. Photographers can download the pictures to a computer, save the pictures directly to a computer as they are shot, send images to a printer, or share photos via a cellular network the same as with a camera phone.

Take last summer's World Cup, for example. As fans screamed, professional photographers sent pictures of Zinedine Zidane head-butting Marco Materazzi flying to photo editors' screens around the globe. The cameras' Wi-Fi transmitters sent the images wirelessly to a nearby colleague with a laptop, who in turn sent them zipping around the world.

The Wi-Fi advantage for professional photographers is apparent—but what about the rest of us? Do we have a use for this feature? Camera manufacturers are betting we do. Increasingly, wireless technology is incorporated into high-end digital cameras, as well as in the point-and-shoot models available to the home consumer. Kodak set the ball rolling by announcing a wireless-enabled, point-and-shoot digital camera at the CES trade show in 2005. Nikon and Canon threw their hats into the ring shortly afterward. Sony came on board in March of 2007.

A Must-Have Feature?

I'm predicting it won't be long before we think of Wi-Fi as a must-have feature when we shop for our next digital camera. Picture the next big corporate event, where the office's rising star snaps pictures of schmoozing executives and projects the images on the wall via a projector hooked to a laptop. Imagine making a huge splash at your kid's birthday party when you snap pictures of arriving guests, wirelessly zoom the images to a printer, and tuck the picture into the kid's goodie bag moments later. Or, how about your next vacation, when you instantaneously send your vacation pictures to a Web page or to someone's computer?

Even better, consider that Wi-Fi cameras use 802.11b and g computer networking technology to connect to a wireless network. If your home computer is Wi-Fi enabled, you can connect your wireless digital camera to it and download your photos. Say goodbye to card readers and USB cables.

However, there are a couple of things you need to be aware of. First, Wi-Fi-enabled digicams are still new technology—so expect some bugs to iron out. Secondly, Wi-Fi-enabled cameras "talk" only to their manufacturer's propriety software, restricting you to use of that one particular element. (Oh, where have we heard this complaint before in the technology world?)

And lastly, the Wi-Fi capability adds about $100 to the price of the camera, so expect a reduction in camera features as the manufacturers try to make the cameras affordable to home users. Prices vary, but the cameras are more reasonable than you might think.

Today's Technology

Nikon's CoolPix P2 5.2 MP camera is Wi-Fi-capable, and sells at Amazon for around $200. The camera can transfer your saved images to a printer (no computer required), or to a wireless-equipped computer, or can send the images directly to the computer as you take them.

Amazon consumer reviews vary, with some saying the camera works fine, but the Wi-Fi is a dud, and others claiming the Wi-Fi is fine, but the camera is flawed. Still others rave about both, but claim that the Wi-Fi connectivity is difficult to set up. A Photo.net review of the CoolPix P2 and its sister camera, the CoolPix P1, points out that the Wi-Fi support permits sending pictures to a computer fewer than 100 feet away, and that this computer must be running Nikon's photo-management software. Also, when in the wireless mode, the camera offers pure "point-and-shoot" functionality—a fact that will irritate more experienced photographers.

On the plus side, however, the camera supports "slide show" functions, so you can do that corporate party thing mentioned earlier. Imaging-resource.com calls the camera a good choice for beginners or for experienced photographers wanting a "take-anywhere" camera.

Kodak's EasyShare One takes a more ambitious approach. This camera uses a touch screen and a Wi-Fi adapter card (sold separately) so you can plug into any Wi-Fi hotspot and send the pictures wirelessly to any e-mail address stored in the camera. The 4MB camera sells at Amazon for about $175.

Consumer reviews, for the most part, rave about EasyShare One. The camera uses Wireless B (rather than the faster G), but sends at a good rate of 11Mbps. The initial setup is somewhat complicated, however. First you calibrate your screen, next you set the date and time, and then you provide your EasyShare Gallery account information. This free service allows you to upload images to share online via e-mail notification. Finally, you bring up the Wi-Fi system and look for wireless hotspots. When you select one of the hits for a protected hotspot, you enter a password. The camera remembers it for the next occasion. Image-resource.com rates this model as suitable for the novice to the experienced amateur.

The Canon PowerShot SD430 5MP Digital Camera with Wi-Fi capability sells at Amazon for about $300. This camera includes an automatic wireless image transfer and wireless control of camera-shooting functions from a PC. An included wireless printer adapter permits direct printing to any Canon PictBridge-compatible printer. It requires no configuration to print, since the camera is pre-configured to recognize the print adapter.

This camera also provides an interesting Remote Capture feature, which gives you a live view from your camera transmitted wirelessly to your computer screen—where you can use the keyboard to do various configurations. Imaging-resource.com rates this camera as good for the novice and experienced amateur, and a good "take-along" camera for the experienced user.

* * *

Wireless digital cameras have come a long way since 2004, when Concord released the Eye-Q Go, a Bluetooth-enabled digital camera selling for about $130. Allegedly, the camera transferred 7MB of images in 15 minutes. (A USB cable provides an 8-second transfer.) PC World included the Eye-Q Go in its list of the 25 worst tech products of all times, saying, "The Bluetooth was a bust, the camera was crude, and the pictures were awful. Aside from that, it was just fabulous."

Top 10 Ways To Make A Computer Run Faster

Today I am going to be talking about different ways you can make a computer run faster. There is actually a lot you can do yourself that will boost your PC's performance. So lets take a look at different ways we can remedy that slow computer of yours!

1. Free Up Disk Space

A great way to make a computer run faster is to free up some disk space. Windows comes with a disk cleanup tool that helps you free up space on your hard disk. The utility identifies files that you can safely delete without messing anything up, and then enables you to choose whether you want to delete some or all of the identified files.

How to use disk cleanup tool.

* Click Start, point to All Programs, point to Accessories, point to System Tools, and then click Disk Cleanup. If several drives are available, you might be prompted to specify which drive you want to clean.

* In the Disk Cleanup for dialog box, scroll through the content of the Files to delete list. (If you have multiple hard drives you will have to select which one to scan.)

* Clear the check boxes for files that you don't want to delete, and then click OK.

* When prompted to confirm that you want to delete the specified files, click OK.

2. Use Defrag Tool

When you add a file or a new program to a new computer, the hard drive is relatively empty so new data is saved to the hard drive in one whole block. When you need to use that information, the computer can quickly access it because it is all in one place. Defragging your system is definitely a way to make a computer run faster.

How to use defrag tool.

* From the start menu point to "all programs"
* Point to "Accessories"
* Point to "System Tools"
* Click on "Disk Defragmenter"
* The disk defragmenter will display the hard drives on your computer. Just select and click Defragment.

3. Get rid of spyware

Definition

Spyware is software with malicious intent - by design; it does something bad to your computer. Usually, it gets installed without your knowledge. It sometimes takes advantage of the fact that most people click "I Agree" to software licenses without reading them.

The only way to get rid of spyware is to have some kind of scanner, sort of like an anti-virus. In order to make a computer run faster and keep it safer your going to need an anti-spyware program. This is tricky, a lot of the spyware programs out there are malicious and will actually add viruses and spyware to your computer by using the "spyware scanner and blocker". So please remember to be very careful when choosing your anti-spyware program.

4. Find and repair disk errors

Detect and Repair Disk Errors

In addition to running Disk Cleanup and Disk Defragmenter to optimize the performance of your computer, you can check the integrity of the files stored on your hard disk by running the Error Checking utility.

How to run the error checking utility.

* Click Start, and then click My Computer.
* In the My Computer window, right-click the hard disk you want to search for bad sectors, and then click Properties.
* In the Properties dialog box, click the Tools tab.
* Click the Check Now button.
* In the Check Disk dialog box, select the Scan for and attempt recovery of bad sectors check box, and then click Start.
* If bad sectors are found, choose to fix them.
Tip: Only select the Automatically fix file system errors check box if you think that your disk contains bad sectors.

5. Get an external hard drive

Adding an External Hard Drive to your computer will allow you to clear out a lot of the things you don't need to be storing on your normal hard drive.

A great example would be your music or pictures. All those songs and pictures are sitting on your computer making it go slower. You will see a decline in your computers performance as soon as you use over half of your hard drive space.

Moving all your songs or pictures to your external hard drive will free up a lot of space on your main hard drive. You can even move applications such as photoshop or games.

An external hard drive is also handy because it is portable. You can unplug it from your computer and take it to a friends house and plug it in there, sharing photos and pictures very easily.

This is truly a great way to make a computer run faster.
