Quizplus · Accepted Answer

CSMA/CD (Carrier Sense Multiple Access with Collision Detection) is a protocol used in Ethernet networks to reduce the amount of collisions and wasted capacity. With CSMA/CD, devices listen to the network to ensure no other device is currently transmitting before trying to transmit themselves. If two devices transmit at the same time and a collision occurs, CSMA/CD detects the collision and both devices stop transmitting. As a result, the amount of wasted capacity is only the time it takes to detect the collision, which is much less than the time it would take for both devices to fully transmit their data.
