Which Protocol uses CSMA/CA
A
HTTP
B
Wi-Fi
C
TCP
D
IP
E
Ethernet
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/C is part of IEEE 802.11-2020 and is used in wireless networks. CSMA/CD (Carrier Sense Multiple Access/Collision Detection) deals with collisions after their occurrence, resending the data frame in case a conflict occurs during transmission.

Detailed explanation-3: -Therefore, instead of collision detection, WiFi uses a collision avoidance strategy defined by the carrier-sense multiple access with collision avoidance algorithm (CSMA/CA). Using WiFi’s collision avoidance algorithm, each sender transmits data only when the channel is idle, like Ethernet.
