When more than half your posts are starting new threads, you're probably doing it wrong. When you have as many questions as you posed in your OP, including one as vague as "how does it all work?", you're almost certainly doing it wrong.
There are already answers to most, if not all, of your questions already posted in this forum. Do a little reading, and then if you still have questions, find the appropriate thread(s) to post them in. When in doubt, the thread niosocket linked you to is a good start.
