MAC is an acronym for Medium Access Control.

The MAC address is also known as the data link address. It is the address assigned to the NIC (e.g. ethernet network card). The address is a 12 digit hexadecimal number that is normally hard coded or "burned" into the physical board by the manufacturer. No two NIC's can share the same MAC address, so it is guaranteed to be globally unique.
