What is the layer of the OSI model that creates, maintains, and disconnects process communications over the network?

Show Suggested Answer Hide Answer
Suggested Answer: C

The Session layer (Layer 5 of the OSI model) is responsible for establishing, maintaining, and terminating communication sessions between network applications. It ensures that data exchanges remain synchronized and structured.

Data link layer handles error detection and frame transmission.

Physical layer deals with hardware-level transmission.

Transport layer ensures reliable data delivery but does not manage sessions.

I’m a bit confused. I thought the Session layer was responsible for maintaining connections, but I also remember the Transport layer does something similar.

I feel like I studied this in relation to similar questions, and I want to say it's D) Transport, but that might be about data transfer instead.

I think the answer might be C) Session, but I'm not completely sure. I remember it has something to do with managing connections.

I feel like the answer is definitely C) Session, but I might be mixing it up with the Transport layer. They both seem to deal with connections.

I’m confused because I remember the Data link layer handles node-to-node communication. Could it be that one?

I practiced a similar question last week, and I think the Transport layer is more about data transfer, so I’m leaning towards C) Session too.
