Understand the three basic types of computer mice

1] Machine: This is a computer mouse with a rubber or metal ball on the underside that can roll in all directions. The sensor inside the mouse is mechanical and can detect the direction in which the ball moves and move the pointer to the screen in the same direction. You should use the mouse pad under the mouse to run.

2] Optical Machinery: This type is the same as a mechanical mouse except that it uses optical sensors to control the motion of the ball. You should use the mouse pad under the mouse to run.

3] Optical: This type uses a laser to detect the movement of the mouse. You do not need

  Mouse pad, but you can use an optical mouse. Optical mouse does not

  Mechanical moving parts. This type of response is faster and more accurate than mechanical and optical mechanical mice, and now they have been around for a while, and the price is very comparable.

How is the computer mouse connected to the computer?

Serial mouse: These are directly connected to the RS-232C serial port or PS/2 port. This is the simplest type of connection.

PS / 2 mouse: Connect to the PS / 2 port.

  USB mouse

Wireless mice: They are not physically connected to the computer. They rarely communicate with computers using infrared or radio waves. Cordless cables are more expensive than serial and bus mice. The good news is that there are no restrictions or ways to get in your way.
