Hi, Linda, These are not all "network protocols", as I noted already.
It might be useful to describe them all as "services", though. I.e., to replate "network protocols" with "services" (or maybe even "networking services" - to distinguish them from OS services, but not give the impression they belong at the "network" layer).
