Computer Networks Questions

Multiple choice

Which of the following is the correct transmission path in hops for a packet switching network that contain n nodes in a bidirectional ring form?

  1. Packet switching does not observe any transmission path in hops.

  2. Best case = 2, average case = 2, worst case = 2

  3. Best case = 1, average case = n/4, worst case = n/2

  4. Best case = 1, average case = 1, worst case = 1

  5. None of the above

C Correct answer
Explanation

This is the case of ring topology,  which has such type of transmission paths in hops.

Multiple choice

Which of the following is/are false about message switching or packet switching?

  1. The data sent in message switching is of limited size.

  2. The data sent in packet switching is of limited size.

  3. The packet switching technique divides data in to multiple packets before sent in the network.

  4. The message switching technique can sent arbitrary long data units.

  5. None of the above

A Correct answer
Explanation

The data packets do not have any limit in message switching technique.

Multiple choice

Which of the following is/are possible in case of pure ALOHA versus slotted ALOHA at low load?

  1. The transmission delay will be less in slotted ALOHA.

  2. The transmission delay will be negligible in case of pure ALOHA.

  3. Both slotted and pure ALOHA will have transmission with the same rate of delay.

  4. There will be no collision or delay possible in case of low load.

  5. None of the above
