NO COMPUTER MOUSE TRAFFIC SIGN
In computing, a mouse functions as a pointing device by detecting two-dimensional motion relative to its supporting surface. Physically, a mouse consists of a small case, held under one of the user’s hands, with one or more buttons. It sometimes features other elements, such as wheels, which allow the user to perform various system-dependent operations, or extra buttons or features can add more control or dimensional input.
