What are the rules and positions in volleyball?

Question
Hi...
What are the rules in volleyball?
How has the game evolved from its original setting?
Where was the game invented?

Answer
You can find the answers to each of these by simply googling each topic.  It would take me pages upon pages to answer each of these.  There are publications printed regarding the rules, and the evolution of the game is too broad to narrow down into a few paragraphs.  If you run into any roadblocks with your study, please shoot back more specific questions.  Thanks.
