The computer has been one of the most amazing and fruitful discoveries man has ever made. It has revolutionized the way man does his things. The way he eats, drinks, sleeps and even thinks. And computer itself has evolved over the years. From the Eniac I to the hand-held palmtops in executives` hands today, computer has changed with the technology. And it has changed our lives too.
The latest addition to this revolution of technical upgrading of computers is the dual-core processor technology. It refers to the CPU (Central Processing Unit- the brains of the computer) that possesses two independent and complete execution cores for each of its two processors. The concerned CPU contains two combined processors along with their cache memories and their respective controllers integrated into a singular circuit (commonly known as a silicon chip).
The dual-core process computer is suited to multitasking and handling miscellaneous tasks (often unrelated to each other). Because its CPU has two completely independent execution cores and both have independent interfaces to the front bus, it has excellent capacity to execute several programs and tasks simultaneously. Similarly, dual-core process computers may have more processor cores which is actually named as a multi-core process computer. These are highly efficient machines to conduct intensive tasks of computing or program execution at the same instance of time.
The Pentium dual-core process computer is the most preferred brand of computer in the market. It has x86-architectured microprocessors integrated onto its circuit. The 32-bit Yonah processors are a base for mobile computers while the 64-bit Allendale processors are maintained for the desktop computers. Both have absolutely different architecture as far as microprocessor technical build is concerned.
By early 2007, Intel decided to launch dual-core process computers in the field of notebooks or laptops too. This was a very important and vital decision as there were no other rivals in this phase if the market of computer architecture. Intel had only decided to launch the dual-core process computer system applying to notebooks on the behest of notebook or laptop manufacturers. The first processors to appear in notebooks using the dual-core process computer technology were the Pentium T2060, T2080 and a 32-bit Pentium M based on the Yonah core with a 1 MB L2 cache, instead of the usual 2MB cache memory.
Intel had forced a return of the Pentium brand to the market arena on 2006 with a host of low-cost single core Conroe-L core architecture processors with a 1 MB cache. These were numbered `1` to distinguish them from dual core process computer cores that had been labeled with the digit `2`.
More recently, on June 3, 2007, Intel released desktop dual-core processors from the Pentium brand. They were named as E2140 and E2160. September 2007 saw the late release of a better and updated model named E2180. These processors support the Intel64 extensions, because of their Allendale derived Core architecture. The power of these dual-core process computers was very imminent as most companies` demands exceeded supply over these multi-processor machines.
Dual-core process computer systems have taken over the world of computing today. As of its multi-tasking ability, it has gained world-wide acclaim due to its efficient, quick and yet superior quality program execution and task completion abilities. Heavier programs and complex games may be run with these dual-core process computer systems at the regular pace of conventional single-core processor systems did with light programs on the execution chart.
The age of computers had begun a long time back. But the age of sleek and efficient computing with the help of razor-edge technology has just begun with the dual-core process computer systems.

How To Clean A Flat Screen Monitor
Flat screen monitors, also known as LCD monitors, are a little different than their CRT cousins when it comes to cleaning. Your standard CRT monitor has a glass screen and be cleaned in pretty much the same way as you would any other glass in your home or office.
Flat screen monitors, however, require a bit of special care when cleaning. Their displays are much more sensitive and are easily scratched and damaged.
Follow the easy steps below to safely clean your flat screen monitor in just a few minutes.
Here's How:
1. Turn off the monitor. If the screen is dark, it will be easier to see the areas that are dirty or oily.
2. Use a dry, soft cloth and very gently wipe the screen. A great choice would be the microfiber type of cloth used to clean eyeglasses. See Tip #1 below for kinds of cloths to avoid.
3. If the dry cloth did not completely remove the dirt or oil, do not press harder in an attempt to scrub it off. Pushing directly on the LCD screen can often cause pixels to burn out.
4. If necessary, dampen the cloth with distilled water or with an equal ratio of distilled water to white vinegar. See Tip #2 below for products to avoid.
Many companies also sell small spray bottles of special cleaner for flat screen monitors but the vinegar mixture is usually just as effective.
5. The plastic edge that surrounds the screen can be cleaned with any multipurpose cleaner but take care to avoid contact with the screen itself.
Tips: 1. Avoid using paper towels, toilet paper, tissue paper, or something like your shirt to wipe the LCD screen. These non-ultrasoft materials can easily scratch the screen.
2. Avoid cleaning products that contain ammonia, ethyl alcohol, acetone, toluene, ethyl acid, or methyl chloride. These chemicals can react with the materials that the LCD screen is made of which could yellow the screen or cause other kinds of damage.
3. Never spray liquid directly on the LCD screen or it could run inside the monitor and cause damage.

After playing around with Vista for a few days, you may want to remove it from your system, and reclaim the hard drive space. Microsoft has made this step very simple as well.
1. Boot your computer in to Windows XP.
2. Ensure you have the Vista DVD image emulated or in the DVD drive.
3. Go to “Start” and “Run”. Type in “e:\boot\bootsect.exe /nt52 ALL /force” (without quotes, and replacing e: with the drive letter of your Vista DVD).
4. Restart the computer, and you will notice the boot selection menu is gone.
5. Format the partition/drive where you had Vista installed.
6. Remove two files (Boot.BAK & Bootsect.BAK) on your XP drive’s root folder (C:), these were backup files of your previous bootloader, now no longer useful.
7. Optional: Restart to ensure it still works.
8. Use your partition software to merge your partitions together.
And now you have returned your computer to its previous state, without Vista and without the new boot loader. If anyone has any issues, please post it in comments and I’ll try to resolve it.

Top 20 Tips To Keep Your System Faster
Follow these tips and you will definitely have a much faster and more reliable PC! Most of the below tips works for windows XP.
1. Wallpapers: They slow your whole system down, so if you're willing to compromise, have a basic plain one instead!
2. Drivers: Update your hardware drivers as frequently as possible. New drivers tend to increase system speed especially in the case of graphics cards, their drivers are updated by the manufacturer very frequently!
3. Minimizing: If you want to use several programs at the same time then minimize those you are not using. This helps reduce the overload on RAM.
4. Boot Faster: The 'starting Windows 95/98' message on startup can delay your booting for a couple of seconds. To get rid of this message go to c:\ and find the file Msdos.sys. Remove the Read-Only option. Next, open it in Notepad or any other text editor. Finally, go to the text 'Options' within the file and make the following changes: Add BootDelay=0. To make your booting even faster, set add Logo=0 to remove the Windows logo at startup.
5. Restart only Windows: When restarting your PC, hold down Shift to only restart Windows rather than the whole system which will only take a fraction of the time.
6. Turn Off Animations: Go to Display Settings from the Control Panel and switch to the Effects Tab. Now turn off Show Windows Content While Dragging and Smooth Edges on Screen Fonts. This tip is also helpful with Windows XP because of the various fade/scroll effects.
7. Faster Start-Menu Access: Go to the Start menu and select Run. Now type Regedit and hit Enter. The Registry Editor will appear on the screen. Now, open the folder HKEY_CURRENT_ USER\Control Panel\Desktop. You should see a MenuShowDelay value. If you don't then do the following: right click on a blank space in the right pane and select New\String. Change the name in the new value to MenuShowDelay. Now that we have the MenuShowDelay value, double click on it and enter 0 in the value data field. This sets the start menu delay to 0 milliseconds.
8. Resolutions: If you are willing to do anything for faster performance from your PC, then try lowering your display resolution. The lower it is, the faster your PC.
9. Turn off Active Desktop: Go to your Display Properties and switch to the Web tab. Uncheck View My Active Desktop As a Web Page. Since the Active Desktop option under Windows 98 uses a lot of system resources, this option can have a dramatic effect on the speed of the whole system.
10. Defragment Often: Windows 98's Defrag tool uses Application Acceleration from Intel which means that when you defragment your drive, data is physically arranged on the drive so that applications will load faster.
11. Take your PC to Bed: Using the Advanced Power Management feature under Windows 98 gives you the option to use the sleep command. That way, you can send your PC to sleep instead of shutting it down and then restarting it. It's as simple as pressing a button and then pressing the same button to wake it up. You can tell Windows after how many minutes/hours of inactivity to automatically sleep the machine in the Advanced Power Management section of the Control Panel.
12. Faster Internet Access: If you use the Internet for reference and the sites you visit are rarely updated then try the following. In IE (the same can be done in Netscape) go to Tools, Internet Options. Next, click on Settings... In the Temporary Internet Files section. Finally, select Never for the first option and double the amount of storage space to use, click OK!
13. Benchmarking: Benchmarking can be very useful when run frequently. It can tell you how your PC's components are performing and then compare them to other machines like yours. For example, when you overclock your PC, you want to know how much more speed you have and whether it is stable. All this and more can be discovered using benchmarking. An excellent piece of software for doing this job is SiSoft Sandra which can be found in the Downloads File Archive!
14. Refresh the Taskbar without restarting: If you in some way change the taskbar, either in Regedit or elsewhere, you can refresh the task bar without restarting. Hold down Ctrl Alt Del, and double click on Explorer. Say Yes to close Explorer, but no to closing Windows. This will refresh the Taskbar and system tray.
15. Quick CD Eject: Instead of pushing the button on your drive, right-click your CD drive letter in My Computer and click on Eject. This will also remove any icons that have become associated with the CD drive.
16. Start Up Programs: Windows can be slowed down when programs run on start up. To eliminate this, check your Start up folder. You can access it from the start menu: Start, Programs, Start Up. Another way to eliminate programs from loading even before Windows actually starts is by doing the following: Click on Start, then Run. Type msconfig. It will take quite a long time for this program to load, but when you finally see it on your screen, explore the different tabs. They all have to do with how quickly your PC boots, so select what you want, and uncheck what you don't want!
17. Fonts: When Windows starts, it loads every single font in the Fonts folder. Therefore, the more fonts you have, the slower the booting process. To get rid of unwanted fonts, simply go to the Fonts folder under c:\windows and remove whatever you don't want. Fonts that have a red letter 'A' as their icon are system fonts, so don't delete them.
18. Stretching Wallpapers: Don't "stretch" your wallpaper in Windows 98 since it actually slows Windows down when you drag icons around on the desktop.
19. RAM Matters: If you have less than 32MB then you should seriously think of upgrading it to at least 64MB. Windows runs much more smoothly with 64MB or higher and tends to use less hard disk space for virtual memory.
20. Partitioning: A very nice little thing you can do to boost system performance. By partitioning your hard drive, splitting one physical drive into several logical ones, you can gain several advantages. 1. If you get a virus or you accidentally format a drive, not all will be lost. 2. By placing the swap file (Win386.swp) on a separate drive, The swap file will be less fragmented and thus, faster. 3. Place Windows on a separate drive and whenever you need to reinstall it, you rest assured that your data is safe on a separate drive. Partitioning can be done using a few programs such as FDisk which comes with DOS. However, FDisk formats everything on the hard disk before partitioning. Alternatively, you can use Partition Magic from Power Quest to partition your hard disk without losing your data.

Hide a Drive
If you don’t want other users stumbling over a drive while browsing the computer through Explorer, this tweak may help out.
Although this tweak will render the drive invisible in Windows Explorer, it will still be accessible through Windows’ search utility, as well as other third-party file managing applications.
Microsoft Office applications will also be able to access the cloaked drive with no problem.
To cloak a drive, open up regedit and go to HKEY_CURRENT_USER/Software/Microsoft/Windows/
CurrentVersion/Policies/Explorer.
Create/modify the DWORD value “NoDrives” to match a corresponding drive letter you wish to hide.
A: 1; B: 2; C: 4; D: 8; E: 16; F: 32; G: 64; H: 128; I: 256; J: 512; etc. To hide multiple drives, just add the values together and enter the sum as the value for the DWORD value “NoDrives”.
To hide all the drives, just enter the value 67108863.
Hope it is useful for u..
