The keyboard is made of several small

number, letter or word written on it. 
Just as you use a pencil to write on a

write with a computer.

CPU
CPU (central processing unit) is the most 
important part of a computer. It is like the 
brain. It does all the tasks that we want 
the computer to do. It also controls all the 
other parts, like the Monitor, Keyboard 
and Mouse. These parts have to be 
connected to the CPU, for them to work.

Moz: Good questions! Let us learn about each of these parts.
A mouse is used to point at items shown on the monitor. 
The mouse usually has two or three buttons and a small 
wheel between the buttons.
Tejas: You said that we can draw pictures using the computer. Can I 
use a mouse for drawing? How can I take the picture home?
Moz: Yes! You can use the mouse to draw pictures. But, you need a 
Printer to print your picture and take it home. 
Jyoti: You said that we can listen to songs on the 
computer. From which of these parts do we 
hear the song?
Moz:  Not from any of these parts. We need 
Speakers to listen to songs. Remember, the 
speakers, printer or any other part will work only if                  
they are connected to the CPU.

After you have studied this lesson, 
you will be able to:
Name the main parts of a 
computer.
Describe functions of these 
parts.
Learning Outcome
Tejas picks up the computer mouse and starts playing 
with it. 
Tejas: What are these buttons for?
Moz: Be careful! We must take proper care 
of the different computer parts. 
Tomorrow we will learn how to do this and then we will 
learn about the buttons.
