No. | CSMA/CD | CSMA/CS |
---|---|---|
1 | Carrier sense multiple access with collision detection | Carrier sense multiple access with collision avoidance |
2 | CSMA/CD is standardized in IEEE 802.3 | 802.11b uses CSMA/CA MAC protocol |
3 | It act as interference between the logical link control sublayer and the network’s physical layer. | It is protocol to implement the distributed coordination function(DCF) of the MAC sublayer. |
4 | Collisions detected within short time | RTS/CTS is used to avoid collisions. |
5 | If a collision is detected, the station aborts the transmission and sends a jamming signal to inform all other stations that a collision has occurred. | Use of RTS/CTS can be enabled or disabled depending on the traffic load(probablility of collisions). |
6 | This protocol is the basis of classical Ethernet LAN. | Used in a network where collision cannot be detected.,Eg. Wireless LAN |
