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.
  • a)
    1 and 3
  • b)
    2 and 4
  • c)
    1,3 and 4
  • d)
    2 and 5
Correct answer is option 'D'. Can you explain this answer?

How does a host on an Ethernet LAN know when to transmit after a colli...
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.

Explanation:

After a collision:
- In a CSMA/CD collision domain, when a collision occurs, the stations involved in the collision must wait before attempting to transmit data again.
- After a collision, the station that detected the collision has the first priority to resend the lost data.

How a host knows when to transmit:
- After a collision, all stations in the CSMA/CD network run a random backoff algorithm.
- Each station selects a random backoff delay period and waits for this period before attempting to transmit data again.
- Once the backoff delay period has expired, all stations have equal priority to transmit data.

Therefore, the correct options are 2 and 5. This is because in a CSMA/CD collision domain, stations must wait until the media is not in use before attempting to transmit data, and after a collision, all stations run a random backoff algorithm before attempting to transmit again.
