[1] [2] It can also be a mechanical device moving the physical computer mouse. In all cases, it prevents sleep mode, standby mode or the screensaver from activating.

For simple software, when the mouse starts to move, the software will count the number of "counts" or "mickeys" received from the mouse and will move the cursor across the screen by that number of pixels (or multiplied by a rate factor, typically less than 1). The cursor will move slowly on the screen, with good precision.
A trackball is a pointing device consisting of a ball housed in a socket containing sensors to detect rotation of the ball about two axis, similar to an upside-down mouse: as the user rolls the ball with a thumb, fingers, or palm the pointer on the screen will also move. Tracker balls are commonly used on CAD workstations for ease of use, where ...

Click of death is a term that had become common in the late 1990s referring to the clicking sound in disk storage systems that signals a disk drive has failed, often catastrophically.
