functional - correlate database records to deliver pertinent advertising
nonfunctional - able to load the page in under 3 seconds - "Sufficient network bandwidth may also be a non-functional requirement of a system"
user - really just use cases - able to search for friends by email address
moved some comments into the answer:
almost any time you say "process" the ability to do the thing is use case, the how of that process is the functional req, the things the system has are mostly nonfunctional(system not software). does that make sense?
Specifically requested example
the actual steps in the login process are functional(form to receive credential, database query to verify validity, set auth token, etc)
and the fact that login should be fast is nonfunctional
