TYPES OF MOUSE

1) WIRELESS MOUSE

Otherwise known as a cordless mouse, these refer to every mouse that
does not have a piece of cable sticking out; Instead of using the
“traditional” cables, wireless mouse use radio frequency (RF) to
communicate with computer devices. There are 2 parts to the equation:

 The mouse itself acts as the transmitter, giving out wireless signals as you move and click.
 The computer will receive those wireless signals and act accordingly.

an attached cable and requires to be plugged into a computer device.

and “inferior” – They are not, and are essentially the same as their
wireless counterparts… Less the wireless circuits, and no batteries
required.
