The Mouse In computing, a mouse Is an Input device that functions by detecting two- dimensional motion relative to Its supporting surface. 1. The Idea for the computer mouse came to Manageable In 1961 at a conference, while thinking about how to make graphical computer interfaces more efficient. 2. The first mouse prototype was made out of wood, a circuit board, and two metal wheels that did not come into contact with the surface it was on.

3.Manageable would go on to refine this prototype in 1972, when he created the ball souse that was the standard type of computer mouse until 1998. The Keyboard In computing, a keyboard Is a typewriter-style device, which uses an arrangement of buttons or keys, to act as mechanical levers or electronic switches. 1 .
