Imagine, you have a magical input device that can take any object from the
real world and put it into your computer. What would you put in and what
would you want the computer to do with it?

HOW COMPUTER WORKS?

A computer works in three steps:
1. We give values and instructions to the computer. This is the

input.
2. The computer then works on the instructions. This is the process.
3. Then, it gives us the result. This is the output.

For example,

5, 10, add 5+10 15

INPUT PROCESS OUTPUT
given through an input device done by the processing device displayed on the output device

A computer uses its input devices (such as keyboard and mouse), processing device (CPU)
and output devices (such as monitor and printer) to follow each stage of the IPO cycle.

Factbot

The letters, numbers and symbols we give to the computer are called instructions.

Experiential Learning Activity

Go to the computer lab with your teacher. Identify the input devices, processing device

and output devices of the computer and write their names.
