Basic Operations of Computers

Basic operations, which a computer performs irrespective of the program are given below:

1. Input - This is for the purpose of inserting or feeding data into the computer by means of an input device like keyboard.
2. Processing - Some kind of processing is done in the computer to take out or transform the data in some way.
3. Storage - The computer stores the result of processing operations for future in some storage device like hard disk or a floppy dick.

These operations are often referred to as IPOS cycle, But the four steps of IPOS cycle_input , processing , output and storage- may not necessarily apper in the same sequence as they are defined.
