A mouse is another important input device of the computer. It is known as a pointing device because it has a pointer arrow on the screen. This arrow moves on the screen as we move the mouse on the mouse pad.
A mouse can have two or three buttons and a tail like wire which connects it to the CPU. Buttons on the mouse help to choose commands. It also has a ball beneath it which makes its movement smooth. The rolling of the ball controls the movement of the mouse.
A mouse is very easy to use. It is held in one hand and mover across on a mouse pad. It is used to move, draw, open and close icone on the monitor.
A mouse has the following actions:
- Double – click
- Drag- and-drop
