Question

How does CSMA/CD react to collisions? A. All systems jam the network, and then all begin retransmitting again. B. Hosts involved in the collision resend the signal immediately C. Hosts involved in the collision send a jamming signal and then run an algorithm before retransmitting D. Collisions do not occur on CSMA/CD E. Hosts involved in a collision send an RTS signal indicating a time frame in which to retransmit

Answer 1

A. All systems jam the network , and then all begin retransmitting again.

Carrier sense multiple access with collision detection (CSMA / CD) is a network protocol for carrier transmission that operates in a medium access control(MAC) layer.Each computer first senses if the wire is idle or not.If the wire is idle ,it sends the data.But if two computer send data at the same time , a collision will happen.The Collision detection Technology detects collision by sending transmission from other stations.On detecting of a collision, the station stop transmitting and sends a jam signal, and then waits for a random time of interval before retransmission.
