Detailed explanation-2: -The MAC layer functions as an adaptation layer between the physical layer and the upper protocol layers. Its main task is to receive MAC service data units (MSDUs) from the layer above, encapsulate them into MAC protocol data units (MPDUs) and pass them down to the physical layer for transmission.
