What is buses?

[Gulliver]

Pro Tools is designed to work like a standard audio mixing board. If you have never used a mixing board, you will need to learn the basics. The best way to learn is to have someone with at least a small recording studio show you. I think reading it in a book or thread will only confuse you.

I have a few questions about recording in general:
what is bus 1, 2, 3, ... what should I use it for?
what is the master fader track and aux input on pro-tools?
can someone explain it to me? or just show me where I can learn? Thanx
