"While talking" is an adverb clause; it describes in what circumstance (how/when) the teacher knocked over his glass, the PM sneezed, the newscaster skilfully pointed out the fronts without even looking at them, or whatever. An adjective clause describes the subject of the sentence (ex.: "The quetzal, native to South America, is viridian to teal in colour."), and you can think of a noun clause as any phrase that represents a single person/place/thing (ex.: "The only thing we have to fear is fear itself", "Anyone who would stoop to that low is despicable", "I've never condoned that sort of thing", "That thing the NSDAP called nationalism frightens me"). Noun and adjective clauses can get a little sketchy sometimes, but I don't think that's in the scope of this question.
