Information theory and coding

                                     A Mathematical Theory of  Communication , Shannon  stimulated a body of  research that  has evolved into the two modern fields of   Information Theory and Coding Theory. The theoretical contribution of Shannon’s work in the   area of channel coding was a useful definition of “information” and several “channel coding theorems” which gave explicit  upper bounds, called the channel capacity, on the rate at  which “information”  could be transmitted  reliably on a given   communication channel. Applications of Information theory and coding include  lossless data compression  eg: ZIP files,  and  Lossy data compression eg:MP3s and JPEG.
