Learning how to build a computer can be mastered by starting with a list of parts. First on this list is the computer case. Of course this is not the most important part, but, without it where would you put all the other parts? Generally the computer case comes with the computer power supply, but, they can be purchased separately. The bigger the case, the bigger the power supply, the more it costs.

The next thing to add to the list is the motherboard. This is a printed circuit Board containing all of the wiring and electronics necessary to run the computer. It requires several screws to attach it to the case. They should be included. Also, there are some electrical connections to be made to the case. You can select a motherboard that has basic circuitry on board which connects to; a modem, the monitor, communications devices, printers, a network, Speakers and microphone, and USB ports for the mouse and keyboard. The other option is to have these features on separate interface circuit cards plugged into expansion slots on the motherboard, which will provide higher quality performance. Using separate expansion cards on the motherboard adds to its overall cost.

Now you are ready to add the CPU (central processing unit) to the list. It will be inserted into a special socket on the main board. The CPU requires a fan and a heat sink, and a device to secure it to the motherboard. Compatibility of the CPU and the motherboard is a must.

Add computer memory (RAM) to the list. This is the short term high speed memory the computer uses performing all of its functions. It comes in various sizes up to 8 gigabytes, and larger sizes are coming. Also, it is inserted into special sockets (multiple sockets) on the motherboard. You can have as much memory as you need and can afford, up to the limits of the motherboard. The RAM must be compatible with the motherboard.

Continuing with how to build a computer, everything on your list so far is required. Now we are adding items that are optional, but, desired. The first of these is the hard disk drive, which is present on most computers. This is used as the computers long term memory; it has a very large storage capacity. The hard drive can store data when the power is turned off for lengthy periods. The data connector on the hard drive must match the one on the motherboard. As an option to the hard drive, now you might choose a solid state drive. The SSD has many advantages and some disadvantages, it is up to you to evaluate which suits your needs.

The DVD drive, the CD drive, and the floppy disk are devices that store data on removable media. The difference between them is recording method and capacity. At this time the floppy disk is being phased out because of its lack of capacity. These devices are used to input data, such as programs and games. They are also used for copying data and archiving.

This is the parts list for the computer case and everything in it. It is the beginning of how to build a computer. For computer parts that are outside the computer case look at peripheral devices. Now you must acquire these items using computer shopping resources and cool computer accessories and supplies. Select the parts that will satisfy your needs and fits within your budget.

When evaluating computer parts for how to build a computer look to the manufacturers, the online computer stores, the retail stores, and knowledgeable friends and family; they all should be able to supply you with some good information.
