In computing, a mouse is a pointing device that functions by detecting two-dimensional motion relative to its supporting surface. Physically, a mouse consists of an object held under one of the user's hands, with one or more buttons. (Although traditionally a button is typically round or square, modern mice have spring-loaded regions of their top surface that operate switches when pressed down lightly.) It sometimes features other elements, such as "wheels", which allow the user to perform various system-dependent operations, or extra buttons or features that can add more control or dimensional input. The mouse's motion typically translates into the motion of a cursor on a display, which allows for fine control of a graphical user interface.
The name mouse originated at the Stanford Research Institute and derives from the resemblance of early models which had a cord attached to the rear part of the device (suggesting the idea of a tail) to the common mouse.[1]
The first marketed integrated mouse, shipped as a part of a computer and intended for personal computer navigation, came with the Xerox 8010 Star Information Systemin 1981. However, the mouse remained relatively obscure until the appearance of theApple Macintosh. The use of mice with desktop computers is now ubiquitous and they are widely available for separate purchase.
