Seriously if you want to learn all of this you have been given webistes to look at. Go to Barnes and Noble or to Books-A-Million and buy a Idiots guide to engines or something. You are going to get on everyones nerves (and apparently already are) by going into all the forums and asking the same questions about how engines work. Find a friend to talk to in person or something. Do a little research all this stuff isnt too hard to figure out. But youre like a computer spaz posting all over the place about this.

Edit:
If you want to learn about DSMs (Mitusbishi/Eage) go to Http://www.vfaq.com
