I/O Unit

The Input/Output unit receives values from sensors and delivers outputs to transistors in the power amplifiers. Data is transferred internally to and from the CPU.

In your home computer, most I/O is handled by the mother board, which takes care of the mouse, keyboard, monitor, printer and communication ports. Extra I/Os can be fitted, e.g. modem, network or sound.
