| CSMA/CD | CSMA/CA |
|---|---|
| Full form of CSMA/CD is carrier sense multiple access with collision detection. | Full form of CSMA/CA is carrier sense multiple access with carrier avoidance. |
| CSMA/CD detects the collision, and once the collision is detected, then it stops continuing the data transmission. | CSMA/CA does not deal with the recovery of the collision. |
| Wired installation is used in a CSMA/CD to detect the collision. | Wireless installation is used in a CSMA/CA as it avoids the collision. Therefore, it does not need a wired network. |
| An 802.3 Ethernet network uses CSMA/CD. | An 802.11 ethernet network uses CSMA/CA. |
| CSMA/CD takes effect after the occurrence of a collision. | CSMA/CA takes effect before the occurrence of a collision. |
