Information on Collision Detection (CD)

In a carrier-sense multiple access (CSMA) media-access control protocol, a collision occurs when two stations attempt to transmit at the same time. Since the messages interfere with each other, the collision must be avoided or detected. In collision detection, each station to listen to the network after transmission. If another station has transmitted at the same time, both stations stop transmitting and wait a random period of time before trying to transmit again.
