What is Medium access control?
{{cleanup|reason=Page describes only MAC addresses, which exist as their own page, rather than the protocol|date=December 2019}} {{IPstack}} A '''Media Access Control address''' (often shortened to '''MAC address''') is a 48-bit code which allows a [[computer]] to be part of a [[computer network]]. Usually, a computer has only one MAC address. Each computer has a MAC address which identifies it uniquely on the network. No other device on the Internet will have the same MAC address. A MAC address contains two pairs of 24-bit [[hexadecimal]]s: the first pair is the international standard identifier of the [[International Organization for Standardization]] (ISO) and the last pair is the serial number for the [[Network card|network interface card]] to uniquely identify the card. {{tech-stub}} [[Category:Computer networking]]
