Explanation:
Detailed explanation-1: -IEEE 802.11 wireless LANs use a media access control protocol called Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA).
Detailed explanation-2: -CSMA/CA is generally used in wireless networks. CSMA/CD is generally used in wired networks. CSMA/CA minimizes the risk of collision. CSMA/CD reduces the recovery time.
Detailed explanation-3: -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.
