Question

Which layer is used to link the network support layers and user support layers?

(a) session layer

(b) data link layer

(c) transport layer

(d) network layer

I have been asked this question during an online exam.

My question comes from Reference Models topic in section Computer Networks Introduction of Computer Network

Answer 1

Correct answer is (c) transport layer

For explanation I would say: Physical, data link and network layers are network support layers and session, presentation and application layers are user support layers. The transport layer links these layers by segmenting and rearranging the data. It uses protocols like TCP and UDP.
