How does a host on an Ethernet LAN know when to transmit after a collision has occurred?
1.In a CSMA/CD collision domain, multiple stations can successfully transmit data simultaneously.
2.In a CSMA/CD collision domain, stations must wait until the media is not in use before transmitting.
3.You can improve the CSMA/CD network by adding more hubs.
4.After a collision, the station that detected the collision has first priority to resend the lost data.
5.After a collision, all stations run a random backoff algorithm. When the backoff delay period has expired, all stations have equal priority to transmit data.
Answer: D
Once transmitting stations on an Ethernet segment hear a collision, they send an extended jam signal to ensure that all stations recognize the collision. After the jamming is complete, each sender waits a predetermined amount of time, plus a random time. After both timers expire, they are free to transmit, but they must make sure the media is clear before transmitting and that they all have equal priority.
