ABSTRACT
Information Theory was created by C.E.Shannon in the late 1940s. The management of Bell Telephone Labs wanted him to call it “'Communication Theory” as that is a far more accurate name, but for obvious publicity reasons “Information Theory” has a much greater impact-this Shannon chose and so it is known to this day. The title suggests the theory deals with information-and therefore it must be important since we are entering more and more deeply into the information age. Hence I shall go through a few main results, not with rigorous proofs of complete generality, but rather intuitive proofs of special cases, so you will understand what information theory is and what it can and cannot do for you.
