| Question 27 |
Which of the following statements is TRUE about CSMA/CD
| IEEE 802.11 wireless LAN runs CSMA/CD protocol | |
| Ethernet is not based on CSMA/CD protocol | |
| CSMA/CD is not suitable for a high propagation delay network like satellite network | |
| There is no contention in a CSMA/CD network |
Question 27 Explanation:
For CSMA/CD requires that sender is to be transmitting atleast till the first bit reaches the receiver. So the collision will be eliminated in case if it is present.
For networks with high propagation delay this time becomes too long hence the minimum packet size required becomes too big to be feasible.
For networks with high propagation delay this time becomes too long hence the minimum packet size required becomes too big to be feasible.
