Here is a quick explanation of the various levels of Air Traffic Control (ATC). This video was made by ATC students for a competition. Please excuse any inconsistencies that you might see as they are still students. Well, by now some of them might be out in the real world as this is a couple of years old. Still, it gives you a pretty good feel for the different groupings of Air Traffic Controllers that you would deal with on a typical flight.
Enjoy!
