What about this?
'telecommunications' is a noun, and nouns can function as adjectives.
What kind of providers? Telecommunications providers. Providers who deal in telecommunications.
What kind of cars? Fasts cars. <--this is wrong? and this is right 'telecommunications providers'? I still don't really understand why it isn't 'telecommunication providers' without the -s. Why do I need to have a 's' there?
