Media Access Control layer

Show me everything on The OSI Model

- In the Open Systems Interconnection (OSI) model of communication, the Media Access Control layer is one of two sublayers of the Data Link Control layer and is concerned with sharing the physical connection to the network among several computers. Each computer has its own unique MAC address. Ethernet is an example of a protocol that works at the Media Access Control layer level.

The other Data Link Control sublayer is the Logical Link Control layer.
