Question

The total nodal delay includes:

propagation delay

transmission delay

processing delay

all of the above

none of the above

Answer 1

Answer:

all of the above

Explanation:

Total nodal delay is the sum of all types of delay.There are basically four types delay that are as following:-

1. Processing Delay.
2. Propagation Delay.
3. Transmission Delay.
4. Queuing Delay.

T(nodal)=T(processing)+T(propagation)+T(transmission)+T(queuing).

Where T is the delay time.We are given with propagation,transmission and processing.Nodal delay includes these 3 delays.

Hence we conclude that the answer is all of the above.

Answer 2

Answer: All of the above

Explanation:

The total nodal delay is the total sum of propagation, transmission and processing delay in a particular network. If a packet are transmitted from one node to another node in the network, then the packet suffers from various type of delay in the network.

• Propagation delay is the amount of time that is taken by the device from the sender to the receiver along with the signal header.
• Transmission delay is the total time that is required for pushing the bits present in the packets on the wire/link.
• Processing delay is the time taken by the router to process in the packet header and it is the key component of the network delay.
