Question 6
|
Both hosts and routers are TCP/IP protocol software. However, routers do not use protocol from all layers. The layer for which protocol software is not needed by a router is
|
Layer – 5 (Application)
|
|
|
Layer – 1 (Physical)
|
|
|
Layer – 3 (Internet)
|
|
|
Layer – 2 (Network Interface)
|
Question 6 Explanation:
Router works on three layers which are physical layer, data link layer and network layer. It do not works on application layer. So the answer is option(A).
Router can connect two different networks like ethernet and token ring because it have two physical layer, two data link layer and one network layer to change the frame format according to the respective network
Router can’t connect two networks which are using different protocols like one is using TCP/IP and other one is using ATM. For connecting such networks GATEWAYS are used because the works on application layer.
