The first thing that should be known is: what exactly are the main components of a computer; what is it inside that box that makes everything happen? Computers are made up of 4 main components: the motherboard, the Central Processing Unit, the Graphical Processing Unit, and the Hard Drive. Each of these parts serves their own unique, yet equally important function. The motherboard is the main circuit board of the computer; it is what ties everything together.

The other parts that the computer would be useless without, the mouse, keyboard, monitor, and speakers are known as peripherals, they work outside the computer's housing and allow you to manipulate data. They will be covered on another page.
