CSMA/CA stands for Carrier Sense Multiple Access / Collision Avoidance is a network protocol for carrier transmission. Like CSMA/CD it is also operated in the medium access CONTROL layer. Unlike CSMA/CD(that is EFFECTIVE after a collision) CSMA / CA is effective before a collision. Let’s see the difference between CSMA/CA and CSMA/CD:- S.NO CSMA/CD CSMA/CA1. CSMA / CD is effective after a collision. Whereas CSMA / CA is effective before a collision.2. CSMA / CD is used in wired networks. Whereas CSMA / CA is commonly used in wireless networks.3. It only reduces the RECOVERY time. Whereas CSMA/ CA MINIMIZES the possibility of collision.4. CSMA / CD resends the data frame whenever a conflict occurs. Whereas CSMA / CA will first transmit the intent to send for data transmission.5. CSMA / CD is used in 802.3 standard. While CSMA / CA is used in 802.11 standard.6. It is more EFFICIENT than simple CSMA(Carrier Sense Multiple Access). While it is similar to simple CSMA(Carrier Sense Multiple
