Detailed explanation-1: -It was developed to minimize the potential of a collision occurring when two or more stations send their signals over a data link layer.
Detailed explanation-2: -It is used to prevent collision rather than collision detection on the shared channel. CSMA CA avoids wasted transmission of data over the channel. It is best suited for wireless transmission in a network. It avoids unnecessary data traffic on the network with the help of the RTS/ CTS extension.
Detailed explanation-3: -Wireless networks must avoid collisions to ensure packets reach their destination.
Detailed explanation-4: -CSMA/CA tries to reduce the frequency of these collisions and provide a plan at the same time on how to proceed if a collision does occur. The protocol is also important because the transmissions in the wireless networks cannot run in the same order (due to the technology used) as they would have done with a cable.
