A media access control (MAC) address is a unique identifier assigned to network interfaces for communications at the data link layer of a network segment. MAC addresses are used as a network address for most IEEE 802 network technologies, including Ethernet and WiFi.
MAC address structure
A MAC address is comprised of six octets or in other words, six 8 bit long segments. The first three octets make up the Organisationally Unique Identifier (OUI), i.e., it can be used to identify the device's manufacturer. Refer to the figure below for a visual representation:
