Forum:Our of curiosity, how do tournaments work?

So I've never been to a tournament, how do they work? Like, do they record what your deck, side, and extra decks are and you have to stick with those exact cards the entire time? Can you switch out cards between games (not rounds)? Do you know what your opponent is playing before you duel them? Do games have time limits?

Also, I've seen some people say something like, "This card I will put in my deck from my side if I am going first." How can you do that? Do you not have to switch out your cards inbetween rounds?
