What is the Mouse?

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.

A computer helps us to learn about any subjects in the world. It has introduced to the schools few years ago. It gives opportunities to open our eyes towards the world. The important units of a computer are the Monitor, the Central Processing Unit (CPU), Keyboard and the Mouse. As well as software is also an important part of a computer.

I also have a computer at home. I do some lessons using it when I am at home. I know how to access the Internet and get the information which I want using the Internet. Using the computer is one of my favorite hobbies.
