A mouse is a pointing device. We can use the mouse to click on icons on the monitor screen and to open the programs in a computer.
We can use it easier than the keyboard. The mouse can be categorized into two types according to the technology. They are Mechanical Mouse and Optical Mouse. There is a rubber ball in mechanical mouse. It rotates when we move the mouse on a surface.
As well as there are some rollers with the rubber ball in a mechanical mouse. When the ball is rotating, these rollers are also rotating. These rotations make signals and the signals are sent to the CPU through the cable.
A light beam is used in Optical mouse instead of the rubber ball. These mice are more expensive than the mechanical mice. The light sensor gets the light beam when the mouse is moved and the electrical signals are sent to the CPU using the cable.
Optical mice are often used these days. People do not like to use mechanical mice because of some problems. We have to clean them again and again. We can use optical mice for a long time as there are no moving parts inside the mouse.
