What is MAC (Medium Access Control)?

A medium access control sublayer is the layer that controls the equipment answerable for cooperation with the wired, wireless transmission medium. The medium access control (MAC) is a sublayer of the data link layer of the open system interconnections (OSI) reference model for information transmission. It is answerable for flow control and multiplexing for transmission medium. It is answerable for encapsulating frames so that they are suitable for transmission through the physical medium.
