MAC Address
Media Access Control Address. A unique physical address of a network card. For Ethernet, the first
three bytes are used as the vendor code, controlled and assigned by IEEE. The remaining three bytes
are controlled by each vendor (preventing overlap), therefore, every Ethernet card is given a unique
physical address in the world, being assigned with a different address from other cards. For Ethernet,
frames are sent and received based on this address.
