No anyone system can depend and control another system. In the Random access protocol, all systems are equal. The media access control protocol is divided into three protocols: The Random access, the Controlled-access, and the Channelization protocol.

The Sub-layer of the data link layer is shown in the figure below. The lower sub-layer is responsible for multiple access resolution that is called media access control (MAC). The upper sub-layer is responsible for flow control and error control that is called the logical link control layer.

Multiple Access Control: The data link layer is separated into two sub-layers.
