This is a list of device bit rates, or physical layer information rates, net bit rates, useful bit rates, peak bit rates or digital bandwidth capacity, at which digital interfaces of computer peripheral equipment and network devices can communicate over various kinds of buses and networks.The distinction can be arbitrary between a bus, (which is inside a box and usually relies on many parallel wires), and a communications network cable, (which is external, between boxes and rarely relies on more than four wires).
