Collecting baseline information on involves listing the types of operational protocols used throughout the system.

Operational protocols

Explanation:

Operational protocols is used to document  the handling of samples, the methods used in their analysis, and the quality of the results generated in an experimental analysis. These are used in almost every field from military to organizations.

There are different types of operational protocols such as TCP, IP, IPX, NETBIOS etc. The baseline information helps to collect information on them. It tells how they have performed and if any old protocols can  be interchanged by the new protocols.

In a system there can be many types of protocols prevalent so collecting baseline information helps to list them out for their assessment.

given the options, i would say your best bet is c. the modem supports up to 56 kbps, which is too low for video streaming. dial up modems use actual phone lines, which only can go up to 56 kbps as that's more than sufficient for traditional phone calls. this is also the reason why when a dial-up modem connects, you hear all those sounds. it's literally using the phone line to establish a connection.
