All computer systems perform the following five basic operations:

1.      Inputting: The process of entering data and instructions into the computer system.

2.     Storing: Saving data and instructions so that they are available for initial or for additional processing as and when required.

3.     Processing: Performing arithmetical operations or logical operations on data in order to convert them into useful information.

4.     Outputting: The process of producing useful information or results for the user such as a printed report or visual display.
