I/O Unit

WARNING: This page is about a different car, the 2003 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.

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.
