You were already given the answer by others in this thread. My question to you was to judge what you already know, since you never described this. I was hoping to build on top of the knowledge that you currently have and figure out if an explanation at the level that you can comprehend can be made.
But in this post alone, I've written way more than you have in all your posts in this thread combined. If you are not willing to put some effort into make such explanation, then I'm bowing out.
