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).
