Detailed explanation-1: -Carrier sense multiple access/collision avoidance (CSMA/CA) is a protocol for carrier transmission in 802.11 networks.
Detailed explanation-2: -CSMA/CA is used mostly in wireless networks. This is because wireless networks often have multiple stations that can see an access point, but not one another. A Wireless Access Point (WAP) is crucial when setting up a wireless network.
Detailed explanation-3: -CSMA/CA is effective before a collision. CSMA/CD is effective after a collision. CSMA/CA is generally used in wireless networks. CSMA/CD is generally used in wired networks.
Detailed explanation-4: -The IEEE 802.11 wireless standard uses the carrier sense multiple access with collision avoidance (CSMA/CA) as its MAC protocol (during the distributed coordination function period). This protocol is an adaptation of the CSMA/CD of the wired networks.
Detailed explanation-5: -IEEE 802.11 wireless LANs use a media access control protocol called Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA).
