What is the difference between CSMA/CD and CSMA/CA?

CCNA - Interview Questions

CSMA/CD stands for Carrier Sense Multiple Access with Collision Detection. It is a media access control method used in local area networking using early Ethernet technology to overcome the occurred collision.

CSMA/CA stands for Carrier Sense Multiple Access with Collision Avoidance. It is used in the wireless network to avoid the collision.

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.
