The CSMA stands for Carrier sense multiple access a method for accessing underlying shared channels eg LAN for sending a frame. Explain the need for different types of MAC layer protocols like ALOHA CSMA CSMA-CA and CSMA-CD Different protocols are required for different types of shared media. Carrier Sense Multiple Access Csma Computer Notes CSMA Random Access Protocol CSMA stands for Carrier Sense Multiple Access. . In contrast to CSMACD Carrier Sense Multiple AccessCollision Detection that deals with collisions after their occurrence CSMACA. Within the data link the MAC sublayer implements channel access. CSMACD stands for Carrier Sense Multiple Access Collision Detection is a network protocol for carrier transmission. You must explain your selection clearly in order to receive marks. It is used in the 80211 Ethernet network. It is operated in the medium access control layer. Carrier Sense Multiple Acces
