I feel that the component of a computer is a bit like the central functions of a human body.

The computer consists of different components, which link to each other to make a powerful resource, just like the basis if a human body.

The central processing Unit is very much like the Brian where the source of all the information is derived from. The hard disk and the floppy disk would have to be the long term and short term memory of the brain.

The screen is the face, the speakers would be the mouths, the keyboard as the sensory input such as the ears and the eyes, and the printer that writes as a hand would.

The wires link all this, which is the nervous system that senses the essential functions of the main body. The diverse Races and cultures around represent the different Brands of the computer.

The power plugs is necessary for our basic functioning such as food and the air we breathe, without it we can not function.
