You will now learn about the basic parts of a computer.

CPU

PL E

CPU stands for Central Processing Unit.

The CPU is the most important part of a computer.

It is the brain of a computer. It stores information.

All the parts of a computer are connected to the CPU. The CPU makes them work.

CPU

Monitor

A computer monitor looks like a television screen. Just as the CPU is the brain of a computer, the monitor can be the face of the computer. The monitor shows whatever you type or draw on a computer.

You can also watch movies on it.

SA M

Monitor

Keyboard

A keyboard has many buttons. These are called keys. Some keys are used to type numbers and words.

You can see on the monitor whatever you type on the keyboard.

Mouse The mouse of a computer looks like a real mouse.

The wire attached to it looks like the tail of a real mouse.

Real mouse

PL E

The mouse of a computer usually has two or more buttons. The mouse is always kept on a mouse pad.

Computer mouse

The mouse is a pointing device. It helps us to move the pointer from one place to another on the monitor.

SA M

The mouse pointer

Let us learn about some devices that work with a computer.

Printer

A printer is used for printing information on paper.

If you type or draw something on a computer, you can print it on paper with the help of a printer. These are called printouts.

Printer

FACT FILE

The UPS is normally used with a computer. UPS stands for Uninterruptible Power Supply. It keeps the computer working for some time, even after a power cut.
