Mac Address

The MAC address or Media Access Control is a unique identifier that each manufacturer assigns to their devices that can connect to the network. They consist of 48 bits in hexadecimal form, grouped into 12 pairs of characters and each character is formed by four binary numbers, generally separated by a colon. MAC addresses are used in the data link layer of the OSI model, specifically in the lower Medium Access Control layer. An example of a MAC address could be:
