Question

When collision has occurred then how does a host on Ethernet Lan know when to transmit, more details explanation need?

1. In a CSMA/CD collision domain, stations must wait until the media is not in use before transmitting.

2.In a CSMA/CD collision domain, multiple stations can successfully transmit data simultaneously.

3. 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.

4. You can improve the CSMA/CD network by adding more hubs.

5. After a collision, the station that detected the collision has first priority to resend the lost data.

A. 1 and 3

B. 2 and 4

C. 1,3 and 4

D. 2 and 5

Explanation / Answer

Answer: A

Explanation:

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.
