A troll pretends to be stupid and ignorant of the subject at hand. If you are being confused with a troll, perhaps it's because you fit that template. So, its a wake up call to go educate yourself. Don't come on a board knowing almost nothing and ask a question. Read the last year of posts. Look for questions similar to yours.
Let me put it this way: I know the answer to your question. I don't know it because I asked it and someone told me. I know it because in the last 24 months I've read a ton about this. I educated myself with publicly available sources, and I bought a handful of books on the subject as well. You could have done the same. You have access to the same resources on the Internet I did. And I know the answer and you don't. So you have made no effort to educate yourself.
And the answer to your question would generate more questions from you as you tried to get us to spoon feed it to you. If you want that, go enroll in a class somewhere where the professor is paid. Otherwise read, read, read, until you know how this stuff works. And THEN if you still have your original question ask it, and because it's clearly so original or hard to determine, we'll all learn something new.
