ETYM Old Eng. mous, mus, AS. műs, pl. mys; akin to Dutch muis, German maus, Old High Germ. and Icel. műs, Dan. muus, Swed. mus, Russ. muishe, Latin mus, Greek mys, Skr. műsh mouse, mush to steal. Related to Muscle, Musk.
(Irregular plural: mice).
In zoology, one of a number of small rodents with small ears and a long, thin tail, belonging largely to the Old World family Muridae. The house mouse Mus musculus is distributed worldwide. It is 75 mm/3 in long, with a naked tail of equal length, and has a gray-brown body.
Native New World mice all belong to the family Cricetidae that is represented worldwide. American cricitids, sometimes called mice, include voles and deer mice. Jumping mice, family Zapodidae, with enlarged back legs, live across the northern hemisphere.
Any of numerous small rodents typically resembling diminutive rats having pointed snouts and small ears on elongated bodies with slender usually hairless tails.
A hand-operated data input device that moves the cursor on a computer screen.
A common pointing device. The basic features of a mouse are a flat-bottomed casing designed to be gripped by one hand, one or more buttons on the top, a multidirectional detection device (usually a ball) on the bottom, and a cable connecting the mouse to the computer. By moving the mouse on a surface (such as a desk top), the user typically controls an on-screen cursor. A mouse is a relative pointing device because there are no defined limits to the mouse’s movement and because its placement on a surface does not map directly to a specific screen location. To select items or choose commands on the screen, the user presses one of the mouse’s buttons, producing a “mouse click.” See the illustration. See also bus mouse, mechanical mouse, optical mouse, optomechanical mouse, relative pointing device, serial mouse. Compare trackball.
In computing, an input device used to control a pointer on a computer screen. It is a feature of graphical user interface (GUI) systems. The mouse is about the size of a pack of playing cards, is connected to the computer by a wire, and incorporates one or more buttons that can be pressed. Moving the mouse across a flat surface causes a corresponding movement of the pointer. In this way, the operator can manipulate objects on the screen and make menu selections.
The mouse was invented 1963 at the Stanford Research Institute, US, by Douglas Engelbart, and developed by the Xerox Corporation in the 1970s. The first was made of wood; the Microsoft mouse was introduced 1983, and the Apple Macintosh mouse 1984. Mice work either mechanically (with electrical contacts to sense the movement in two planes of a ball on a level surface), or optically (photocells detecting movement by recording light reflected from a grid on which the mouse is moved).
A small mobile manual device that controls movement of the cursor and selection of functions on a computer display
To manipulate the mouse of a computer.
