Wire speed
In computer networking, wire speed or wirespeed refers to the hypothetical peak physical layer net bit rate (useful information rate) of a cable (consisting of fiber-optical wires or copper wires) combined with a certain digital communication device, interface, or port. For example, the wire speed of Fast Ethernet is 100 Mbit/s also known as the peak bitrate, connection speed, useful bit rate, information rate, or digital bandwidth capacity.
