motherboard layout

Aim:

      To draw a Pentium 4 motherboard layout and mark the processor, chipset IC’s, RAM, Cache, Xtal, Cooling fan, I/O slots, I/O ports and various jumper settings.

Procedure:

CPU Socket

            The processor of the computer will be inserted into the CPU socket. Pentium 4 CPUs are available for many different socket types, including Socket 423, Socket 478, LGA775 and Socket T. Each socket has a different number of pins, and the socket type will be clearly labeled on most motherboards.

RAM Slots

           The main system memory of your computer will be inserted into the RAM slots. There are Pentium 4 motherboards supporting RDRAM, SDRAM and DDR-SDRAM. Examine the instruction manual for your motherboard to confirm which type of RAM it supports before performing an upgrade. Remember that RDRAM must always be inserted in matched pairs.

Drive Connectors

         Any hard drives, optical drives and floppy drives in your computer will be connected to the drive connectors. All of these devices additionally require power to operate, so they will also be connected to the computer's power supply.

Power Supply Connector(s)

          As the name implies, the leads coming from your computer's power supply will be inserted into the power supply connector. Examine your motherboard for an additional 4-pin connector, as well; many Pentium 4 CPUs require auxiliary power from this 4-pin connector in order to operate properly. Ensure that both the main and auxiliary connectors are properly inserted before attempting to power your computer on.

Expansion Slots

           If your computer has any expansion cards, such as video, sound or wireless networking cards, they will be inserted into the expansion slots. For added stability, each expansion card will also be screwed into the computer chassis. Ensure that any expansion cards that you install are screwed into the chassis before powering the computer on.

Rear Ports

           The rear ports will be visible on the back of the computer when the chassis is closed. Depending on your particular motherboard model, these may include ports for video, sound, a printer, USB devices and more. These ports are used by your computer to communicate with all of the external devices that you may use.

Processor:

           The CPU, or the central processing unit, also known as a processor for short, is the brain of every computer. The CPU executes any calculation or process made by the computer.

           The processor uses bits that have either a value of 0 or 1 for all of its calculations ("bit" is short for "binary digit"). Computers store, process and retrieve information by using strings of bits, such as, for example "1011001." All computer programs like Internet browsers, word processors and image manipulation software must be processed by CPUs.

Result:

Thus the motherboard layout was drawn and the parts are marked
