How to build a PC |
|
To Build a PC we need following Material or Accessories or Parts
• CASE or CABINET : First of all you will need a case. Power Supplies come along with these. Also Power Cables, and screws. I always recommend a middle price case as there is less sharp edges than the budget priced ones (I Found this out the Hard way). A desktop or Tower case, it doesn't matter, but I would Recommend a Tower with at least 3 CD-ROM Bays. Remember it is important to buy an AT case for an AT motherboard and an ATX case for an ATX motherboard (Make sure it is P4 , Dual Core , Core2Duo compatible for Pentium 4 and Athlon XP processors), otherwise you will have the wrong power connecters.
• PROCESSOR : Select what you want to go with ( Athlon, Cyrix or Pentium) and the speed. The higher the speed the bigger the price. We recommend, (unless you can afford it) that you don't buy the top of the range processor, try it a few speeds below, this will save you quite a lot of money.
• MOTHERBOARD : Make sure you get a motherboard that is Compatible with your processor. We recommend that you don't get onboard video. It is a cheaper option but not upgradeable. Also make sure that all the cables come along with it. You will need a floppy drive cable, UDMA IDE cable for the hard drive and an IDE cable for your CD-Rom/CD-RW/DVD drive/s.
• VIDEO CARD(optional) : A good AGP video card. Confirm once again if this is compatible with you motherboard. (Checking the motherboard information should tell you what you need, you can usually do this online from the buyer or manufacturer's website.) e.g. if you have an AGP X2 slot on the motherboard, and your Video Card only works on AGP X8. Then you will have problems. You can get video onboard, we don't recommend this option, unless machine is purely for business use.

What is Embedded System? |
|
Embedded systems refer to devices, instruments or large engineering structures/systems that are built to handle one or a few pre-established tasks. The computer controlling the whole thing is built into or 'embedded' within the device.
Cellphones and personal digital assistants (PDAs) are examples of devices with embedded systems. They both perform a specific number of tasks which are controlled by a built-in computer system.
A traffic control system (which remotely controls traffic lights without the need for human intervention) is an example of a large engineering structure with an embedded system. |

Reset BIOS Password |
|
|
You set a BIOS password on your computer. The next time you start up the computer, you forgot what it was. How do you reset it?
1. Open up the computer to expose the motherboard. For normal desktop computers
, you will have to slide the case cover or side door off. For Laptops, remove the keyboard by unscrewing the screws securing it to the unit. 2. Look for a battery on the main board. It will either look like a large watch battery or like half of a AA. 
3. Remove the battery for about 10 seconds. 4. Place the battery back on the motherboard. If this doesn’t work, it is likely that you will need to look in the documentation for your motherboard to learn the jumper that will reset the BIOS password. Source:- http://www.technipages.com |
