What do I Need in a Computer?

For a computer to actually work, it needs several critical internal parts. Those are a power supply, motherboard, hard drive, video card, sound card, the proper RAM for the mother board, a CPU chip, a cooling fan to cool the processor, some sort of external media device such as a DVD-Rom drive, and all the cables needed to connect them to their proper places on the mother board. Outside parts include a keyboard, mouse, monitor, and speakers.
