Q1:
Why does a

need so many
parts?
Good questions! Let us learn
about each of these parts.
• It is like the brain.
• Just as our brain controls all the different
parts of the body and makes them work
together, the CPU controls all other parts
of the computer and makes them work
together.
• the CPU is also the store of all the
information in the computer.
CPU
(CENTRAL PROCESSING UNIT)

• is the most important part of a computer.
• It does all the tasks that we want the
computer to do.
• All other parts of the computer are
connected to CPU.

• A monitor looks like a TV screen.
• The CPU uses the monitor to show us
photos, movies and games.

Power Switch

KEYBOARD
• The keyboard is made of
several small buttons
called “keys”.
• Each key corresponds to
a number or a letter or
some special function.
KEYBOARD
• Just as you use a pencil
to write on a paper, the
computer needs a
keyboard to tell it what
to do.
MOUSE
• 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.
MOUSE
• Clicking the mouse once is called
a single click
• Clicking the mouse twice in
quick succession is called a
double click.
Can I use a mouse for
drawing?
How can I take the picture
home?
YES
You can use the mouse to draw pictures.
But you need a Printer to print your picture and take it
home.
PRINTER
•It is a device that
helps you to print
what you see on
monitor on a
paper.
FROM WHICH
OF THESE
PARTS DO WE
HEAR THE
SONG?
Not from any
of these parts.
•We need
Speakers
to listen
to songs.

songs played on it
