It is an electronic device that works with electricity, has the feature of very fast processing, can store large information in very small areas and can reach this information in a very short time when requested. It can also be called a machine for running programs. Computers are composed of many parts with separate functions, and managing these parts is done by means of special programs in the computer. These programs are called "Operating System".

As it can be understood, the computer and the operating system are inseparable. For this reason, we examine computers in two parts.

We call all the Electronic parts in the computer "Hardware" and all the programs used in the computer "Software".
