Amit, you don't have to worry about anyone throwing you out of the forum just for asking questions. You're not doing anything abusive.
That said, I agree with Steven that it seems like you're struggling with some basic concepts and might need more structured support than we can reasonably offer as a forum. Contra some of the comments here, I don't think it's unreasonable of him to make that observation, although he seems to have missed that you did mention your previous experience in another thread. I'll take some other things up with him privately.
But as you learn those basic concepts better, whether it's from a book or directly with a teacher, I hope you feel welcome to keep coming back with questions.
