IP functions at what layer of the OSI Reference Model?

A user has sent a request to the server. What process does the server go through to determine what service is being requested by the user?

The term segment refers to which layer PDU?

This output comes from a network analysis tool. It lists a group of lines for each header in a PDU, with the frame (data link) header at the top, then the next header (typically the IP header), and so on. The first line in each section has a gray highlight, with the indented lines below each heading line listing details about the fields inside the respective header. You will need to remember some parts of the various headers, and compare those concepts to this output, to answer this question.
