MAC / Media Access Control for Not Yet Techies

"Computer Careers: Using This Technology for Every Network Machine to Have a Unique Name to Identify It"

by Richard Stooker, President Info Ring Press and author of Secrets of Changing to a Computer Career

MAC / Media Access Control address is the unique identifier assigned to every piece of hardware or node on a network. In IEEE 802 networks, the Data Link Control (DLC) layer of the OSI Reference Model is divided into two sublayers: the Logical Link Control (LLC) layer and the MAC / Media Access Control address layer.

The MAC / Media Access Control address layer interfaces directly with the network media. Consequently, each different type of network media requires a different layer.

The MAC / Media Access Control address is used by that sublayer of the Data Link Control (DLC) layer of telecommunications protocols

Each piece of hardware has a different sublayer.

The MAC / Media Access Control address consists of hexadecimal code stored on a ROM chip in the computer's network interface care (NIC). The Windows Internet Name Service (WINS) or Domain Name Service (DNS) can map computer hardware addresses to their corresponding IP addresses.
