What Does Mouse Mean?

A mouse is a small handheld input device that controls a computer screen’s cursor or pointer in conjunction with the way it is moved on a flat surface. The mouse term name originates from its likeness to a small, corded and elliptical shaped device that looks like a mouse tail. Some mouse devices have integrated features, such as extra buttons that may be programmed and assigned with different commands.

The mouse was invented in 1963 by Douglas C. Engelbart from Stanford and later pioneered in 1981 by the Xerox Corporation. Computer users were generally skeptical about the mouse invention until approximately 1984, when the original Apple Macintosh (Macintosh 128K) was released.
