Hi and welcome to the boards
Seeing the questions you have, the best thing for you would be to start reading and not stop reading until you'v answered most of them yourself
In the process, you'll have learned muh more than just this, and will have earned some respect from other members for having done your homeworks and read the already huge amount of information available here
Cheers, and good reading!
