It is a forum rule (see red link above) that you must show your attempt or give your thoughts before we can help you.

Well, you should have a textbook, you should have notes, you do have a teacher that introduced the subject - so it is not like the question is asked in a vacuum, apparently it tries to check what you got from the lecture or from the book. Then, you have access to wikipedia and many other sources on the web - have you tried to consult them? That's how learning works, you look for sources and you check what they say on the subject.

So, what have you checked?
