MAC (Media Access Control) address is a unique identifier assigned to a network interface card (NIC) for use in communication within a network. It is
48 bits long, typically represented in hexadecimal format, such as
00:1A:2B:3C:4D:5E.
Key Points:
· The first 24 bits (organizationally unique identifier, OUI) identify the manufacturer.
· The last 24 bits are the specific NIC identifier.
· It operates at the
data link layer of the OSI model.
· MAC addresses are essential for LAN communication and Ethernet.
