computer works? In this chapter, we are going to learn how a computer works.
IPO Cycle 2.
Have you seen your mother making mango shake for you? This is what she does to
make the mango shake.
1. She puts the mango pieces, sugar and milk in the blender. (This is the input.)
2. The blender mixes all the things. (This is the process.) Debit Card ATM Machine Cash
(Input) (Processing) (Output)
3. She pours the mango shake in the glass. Mango shake is ready to drink. (This is the

INPUT PROCESS OUTPUT
Similarly, we give instructions to the computer; the computer then works on the
instructions and gives us the result.
2.
The letters, numbers, symbols we give to the computer are called data.
The instructions that we give to the computer are called input. The working of the
computer is called processing and the result we get is called output.
IPO Devices
Thus, a computer works in three steps:
A computer is made up of many parts. These parts are also known as devices.
INPUT → PROCESS → OUTPUT Input Devices
This is also called IPO cycle. Let us look at some more examples of IPO cycle. The devices that are used to enter data into the computer and give orders are called
input devices. Some of the commonly used input devices are keyboard and mouse.
