Networking - What is CSMA and CD concept?

What is CSMA and CD concept?

- In CSMA (carrier sense multiple access), presence of any digital signal in a network is checked before transmission. Data transmission occurs only when no signal is sensed.

- CD, Collision detection is responsible for monitoring carrier in order to avoid signal jam.

- It is a set of rules which determine how the network devices respond when two devices attempt to use a data channel simultaneously.

- The standard ethernet network use this CSMA/CD to monitor the traffic physically.

- It is a type of contention protocol.

- Networks using this procedure are easy to implement and do not have deterministic transmission characteristics.
