A mouse is divided into four categories. They
are:
(1)

(4) Cordless Mouse/Wireless Mouse
Mechanical Mouse:
This is the first mouse to hit the market. Now it feels very
uncomfortable to use compared to USB and PS/2 mouse. It works with the help of
a rubber ball. It is used in PI, PII computers. But its connector is 9 Pin
Serial Port in a flat shape.
This is the second mouse to hit the market. This makes the mouse easier
than a mechanical mouse. It also runs on a PIII
computer with the help of a rubber ball. It is
also called Optical Mechanical PS/ 2 Mouse.
Optical Mouse:
This is the third mouse to hit the market. This mouse is much easier
than a mechanical mouse because a laser is used instead of a rubber ball. The
optical mouse is divided into 2 parts depending on the port. They are:
1) PS/2 Port Mouse
2) USB Port Mouse
Cordless Mouse/Wireless Mouse:
This mouse is used for radio waves,
especially on laptops. This is a wireless mouse. That connects to a computer
