Note to Pupils:

Keyboard and Mouse

Keyboard: A keyboard is a tool that we use to type words and numbers into the computer. It has many keys, and some of them are special keys that help us do things quickly.

Mouse: A mouse is a tool that helps us move a small arrow on the computer screen. The small arrow is called a Cursor and is used to point at things on the monitor. We can also use a mouse to click on things and open them.

Both the Mouse and Keyboard are input devices.
