i + TYPES OF MOUSE
There are different types of computer mouse, for example:
Ball Mouse
A Ball Mouse has a hard rubber ball under it. It is rarely used
now because the ball catches dust easily, which causes the
mouse to stop working properly.
Optical Mouse
An Optical Mouse is used the most. It has an LED sensor at
its bottom that helps the pointer on the screen to move. If
you pick up the mouse, you will see a red light glow under it.

the computer through Bluetooth. It is also an optical mouse.
