OSI Model & Encapsulation Practice Questions

One solved question, so you can see how these are marked

A host sends data to a server. In what order does the data pass down through the OSI layers on the sending host?

Application, Presentation, Session, Transport, Network, Data Link, Physical

The OSI model orders the sender's functions from Application down to Physical. Encapsulation adds protocol control information where needed; it does not mean every OSI layer adds a distinct header. The Physical layer transmits signals representing bits, and the receiver processes the layers in reverse order.

Every question in the set below is marked like this. The answers stay hidden until you pick one.
