A MAC address (Media Access Control address) is a unique identifier assigned to network interfaces for communication on a network. It is a 48-bit number typically represented as a 12-digit hexadecimal number, such as 00:11:22:33:44:55.
MAC addresses are essential for network communication because they allow devices to identify each other and communicate data. They are also used for network security purposes, such as access control and intrusion detection.
