Your an IT student and you don't know the answers to these questions?
How the hell do you not know what RTM stands for?
Also you obviously don't know how to use Google as these questions can be answered within 2 minutes just by a simple search.
Are you sure your an "IT Student"? Shouldn't that be... ART Student? Wait, that's taking the piss out of Art students a little bit, at least they would know how to use google!
