The Media Access Control Protocol The tutorial in Chapter 2 , introduced the Ethernet system and provided a brief look at how it works. In this chapter we take a much more detailed look at the original mode of operation used for Ethernet, which is based on the CSMA/CD media access control … Media Access Control (MAC) Tables | Basic Data Media Access Control (MAC) Tables. The term Media Access Control (MAC) probably sounds familiar. This term is typically introduced in lessons on the Open Systems Interconnection (OSI) model's Layer 2—data link layer addressing. Each Ethernet device that is manufactured is assigned a MAC address.

The medium access control (MAC) sublayer is closely associated with the physical layer and defines the means by which the physical channel (medium) may be accessed. It coordinates the attempts to seize a shared channel by multiple MAC entities to avoid or reduce the collisions in it. 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 Media Access Control (MAC) address is the unique hardware address of an Ethernet network interface card (NIC), typically “burned in” at the factory. MAC addresses may be changed in software.
