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 the pointer on a display, which allows a smooth control of the graphical user interface of a computer.
A computer mouse with the most common features: two buttons (left and right) and a scroll wheel (which can also function as a button when pressed inwards)

A computer mouse is named for its resemblance to the rodent.
