Media Access Control (MAC) Address

A data-link layer address that is required for every port or device that connects to a LAN. Other devices in the network use MAC addresses to locate specific ports in the network and to create and update routing tables. MAC addresses are controlled by the IEEE and are also referred to as MAC-layer addresses or hardware addresses.
