Similarly, a computer works on Input ® Process ® Output cycle.

Input Process Output

The data and The computer then After processing

instructions that convert the raw data the data,
is given to a into meaningful computer gives

computer to do information. This is the desired

any specific task called processing . result which

is called input . is known

as output .

Wrong input leads to wrong output. It is called GIGO — Garbage In,

Garbage Out.

Practical Window

Suppose, you get different marks in different subjects and want to calculate

and find out the total marks that you have scored, on a computer. How would
you do it? Explain with the process of Input ® Process ® Output cycle.
