Optical mouse

The optical mouse is used in the present day personal computers. The optical mouse works on the basis of LED – light emitting diode and DSP – digital signal processing. The optical mouse was invented in 1981 by Logical Company. In this, instead of a ball, a laser light is installed, through which this mouse works.

Wireless mouse

This mouse is based on radio frequency without wires, which we call wireless mouse. The design of optical and wireless is the same. There is a transmitter inside the wireless mouse, whose receiver is connected to the CPU. This mouse connects to the USB port (universal serial bus) which we call the receiver. The battery is used to operate the wireless mouse. It was invented in 1991 by Logical Company.
