Detailed explanation-1: -CSMA/CD and CSMA/CA are the two multiple access protocols used for channel access control.
Detailed explanation-2: -(c) CSMA/CD CSMA/CD is an abbreviation of Carrier Sense Multiple Access/Collision Detection. It refers to the multiple access carrier with collision detection. In CSMA/CD, all the stations have the ability to stop data transmission if a collision is found anywhere.
Detailed explanation-3: -CSMA/CD is used by Ethernet. In CSMA/CA collision avoidance is used to improve the performance of CSMA. If the transmission medium is sensed busy before transmission, then the transmission is deferred for a random interval.
Detailed explanation-4: -CSMA/CD stands for Carrier Sense Multiple Access with Collision Detection. It is a network access control method used in Ethernet networks. The purpose of CSMA/CD is to avoid collisions between network devices trying to transmit data at the same time.
