Answer 2

I generally don't just like to give links to Wikipedia, but with such a vague question, I can't think of anything more relevant and/or helpful. You should find some good information and links to start with here (it's not completely trustworthy, so if you're using the information for anything more than to satisfy casual curiosity, be sure to verify):
