Detailed explanation-1: -Carrier-sense multiple access (CSMA) is a medium access control (MAC) protocol in which a node verifies the absence of other traffic before transmitting on a shared transmission medium, such as an electrical bus or a band of the electromagnetic spectrum.
Detailed explanation-2: -Carrier Sense Multiple Access (CSMA) is a network protocol for carriertransmission that operates in the Medium Access Control (MAC) layer. It senses or listens whether the shared channel for transmission is busy or not, and transmits if the channel is not busy.
Detailed explanation-3: -We improve the communication by using the CSMA protocol, which is based on the “sense before transmit” (or “listen before talk”) principle. CSMA (carrier sense multiple access) is a probabilistic MAC protocol in which a node verifies the absence of other traffic before transmitting on the shared transmission medium.
