overview of mouse..answer fast..

Answer 1

Hi,

A computer mouse is a hand-held pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of a pointer on a display, which allows a smooth control of the graphical user interface.

The three main mouse device types are:

Mechanical: Built with a trackball underneath the mouse and mechanical sensors, allowing easy movement in all directions

Optomechanical: Similar to the mechanical type but uses optical, rather than mechanical, sensors to detect trackball movement

Optical: The most expensive. Uses a laser to detect mouse movement, has no mechanical parts and reacts more precisely than other types.
