The medium access control (MAC) is a sublayer Of ____
A
data link layer
B
network layer
C
physical layer
D
application layer
Explanation: 

Detailed explanation-1: -The medium access control (MAC) is a sublayer of the data link layer of the open system interconnections (OSI) reference model for data transmission. It is responsible for flow control and multiplexing for transmission medium. It controls the transmission of data packets via remotely shared channels.

Detailed explanation-2: -The medium access control – commonly referred to as the MAC protocol – is, effectively, a sublayer or MAC sublayer that controls hardware responsible for the communication with a wired, wireless or optical transmission medium.

Detailed explanation-3: -What is Media Access Control? A media access control is a network data transfer policy that determines how data is transmitted between two computer terminals through a network cable. The media access control policy involves sub-layers of the data link layer 2 in the OSI reference model.

Detailed explanation-4: -Media access control (MAC) protocols enforce a methodology to allow multiple devices access to a shared media network. Before LANs, communication between computing devices had been point-to-point. That is, two devices were connected by a dedicated channel.
