D. HDLC
Answer:C
Which of the following is the multiple access protocol for channel access control?
A. CSMA/CD B. CSMA/CA C. Both CSMA/CD & CSMA/CA D. HDLC
Explanation: In CSMA/CD, it deals with detection of collision after collision has occurred, whereas CSMA/CA deals with preventing collision. CSMA/CD is abbreviation for Carrier Sensing Multiple Access/Collision detection. CSMA/CA is abbreviation for Carrier Sensing Multiple Access/Collision Avoidance. These protocols are used for efficient multiple channel access.
