Definition:
A mouse is a pointing device that controls the movement of the cursor or pointer on a display screen. A mouse is a small object you can roll along a hard, flat surface. Its name is derived from its shape, which looks a bit like a mouse, As you move the mouse, the pointer on the display screen moves in the same direction.
History:
It was invented by Douglas Engelbart of Stanford Research Center in 1963. In those days, computers were large and expensive. Using them was very hard because everything had to be typed in by hand, and there was no way to alter things if you made a mistake.After studying and designing for a long time, Engelbart succeeded in inventing a pointing device.At first, it needed two hands to use, but it was changed so that only one hand was needed to use it. This model was more like the mouse that we use today.

Some mice have a ball or LED sensor on its lower surface to detect the movement of a mouse. Basically it looks like a rat. A mouse can have 1 to 6 buttons to click, but most mice have two or three.
Types of mouse:
There are basically two types of mouse:
· Mechanical mouse: Houses a hard rubber ball that rolls as the mouse is moved. Sensors inside the mouse body detect the movement and translate it into information that the computer interprets.
· Optical mouse: Uses an LED sensor to detect tabletop movement and then sends off that information to the computer for merry munching.
