I've read many books and googled many things. You still are unable to answer the questions. Pretending to know things you don't isn't very nice.
I'm not OP btw, just making a point from your replies in some of my threads. You pretend to know things you don't all the time, then when called out on it, say, "use google or read a basic book because I'm not doing the work for you". So it's funny seeing the karma on this thread.
