What is CSMA/CD and how does it work?
What will be an ideal response?
CSMA/CD is the media access method used by Ethernet, which is a set of rules that govern how and when a device can transmit on an Ethernet network. When two devices transmit a signal at the same time, they cause a collision to occur. Then the devices must try to transmit again, and again, causing a bottleneck. To avoid these collisions, CSMA/CD says that a device must first listen to see whether it can detect any other signal on the medium. If no other signal is detected, then the device can transmit. If another device transmits at the same time and a collision occurs, then both transmitting stations must wait for a random period before they can try to transmit again.
