This is a history of computing from its earliest days, when individual mathematicians worked as 'computers' manually making calculations for their rulers, to the ubiquitous pocket-sized devices of the modern day. Subjects range from Babbage's difference engine to the creation of the Bombe and the Colossus in the codebreaking efforts of the Second World War to the fascinating future of the field, including artificial intelligence and the new risks presented by cybercrime. Written by the nephew of the "Father of Modern Computing", Alan Turing, this title provides a unique insight into the history of computers. Alan Turing's popularity has surged since the release of the film "The Imitation Game" in 2014. Accessible format with full-colour illustrations and panels featuring biographies of important figures, accounts of major developments in the field and easily comprehensible explanations of the key concepts.
