Identify two input devices which are used in computer control systems.

Mouse: The mouse is a pointing device that functions by detecting two-dimensional motion relative to its supporting surface. The motion is typically translated into the motion of a pointer on a display, which allows for fine control of a graphical user interface.

Keyboard: A keyboard is a device which uses an arrangement of buttons or keys to act as mechanical levers or electronic switches. Following the decline of punch cards and paper tape, interaction via teleprinter-style keyboards became the main input method for computers.
