| Question 16 |
Assume that Source S and Destination D are connected through an intermediate router R. How many times a packet has to visit the network layer and data link layer during a transmission from S to D?
| Network layer – 4 times, Data link layer – 4 times | |
| Network layer – 4 times, Data link layer – 6 times | |
| Network layer – 2 times, Data link layer – 4 times | |
| Network layer – 3 times, Data link layer – 4 times |
Question 16 Explanation:
Source and destination are hosts. The hosts have all layers but routers have only 3 layers
i.e physical,data link and network layer. The purpose of routers is to just pass on the packet between hosts or networks.
Therefore ,
