On a half-duplex Ethernet LAN, two hosts attempt to send data simultaneously, resulting in a collision. Following this collision, what will the hosts do? (Select all valid answers)A. The destination host sends a request to the source for retransmission.B. The jam signal indicates that the collision has been cleared.C. The hosts will attempt to resume transmission after a time delay has expired.D. An electrical pulse indicates that the collision has cleared.E. The router on the segment will signal that the collision has cleared.F. The hosts will do nothing, as the higher layers are responsible for data error correction and re-transmission.

考题
Which two statements describe the operation of the CSMA/CD access method, which is in use on the Ezonexam network? (Choose two)A. After a collision, the station that detected the collision has first priority to resend the lost data.B. In a CSMA/CD collision domain, stations must wait until the media is not in use before transmitting.C. In a CSMA/CD collision domain, multiple stations can successfully transmit data simultaneously.D. The use of hubs to enlarge the size of collision domains is one way to improve the operation of the CSMA/CD access method.E. After a collision, all stations run a random backoff algorithm.
