The link you sent went to a site where I could download textbooks. I don’t want to down load even a short text book. If you want to convince people of something you need to be willing to answer their questions.
Have it your way, Ditter. I told you that I can't explain it to you in 30 words or less, and directed you to a short text that can answer all of your questions and more.
If you can't be bothered to simply read it, then you're just posturing or picking a fight. I'm not trying to "convince" you (or anyone else) of anything. You wanted an answer, and I gave it to you.
