What is a computer and what are its components?

A computer is a programmable, electric powered machine that has the ability to perform mathematical and logical operations. A computer which is not to be confused with a computer package consists of nine basic components.

1)Motherboard- which is either integrated or non-integrated.
2)CPU or Central Processing Unit/ Processor
3)Power Supply
4)Hard-Drive
5)RAM or Random Access Memory/ Memory
6)Video port (integrated mother board) or Video card (non-integrated motherboard)
7)Sound port (integrated mother board) or Sound card (non-integrated motherboard)
8)Optical drive
9)Case

Now a computer package is basically what you buy from the store. The computer itself, monitor, mouse, and keyboard. The additional components that I listed are called external devices or peripheral devices.
