C) CSMA/CA
D) Token passing

Question

Quizplus · Accepted Answer

In wireless networks, the media access control protocol used is CSMA/CA (Carrier Sense Multiple Access/Collision Avoidance). This is because wireless networks are more prone to collisions due to their inherent nature of shared medium and lack of physical medium sensing. Therefore, CSMA/CA is designed to avoid collisions by using RTS/CTS (Request to Send/Clear to Send) packets and withholding transmission until it receives permission to transmit from the destination.  The other options mentioned, CSMA/CD (Carrier Sense Multiple Access/Collision Detection) and token passing, are not used in wireless networks. Polling is used but is not the primary media access control protocol.
