Computer science development of sophisticated computing equipment. Wilhelm Schickard designed and constructed the first working mechanical calculator in 1623. In 1673, Gottfried Leibniz demonstrated a digital mechanical calculator, called the Stepped Reckoner. He may be considered the first computer scientist and information theorist, for, among other reasons, documenting the binary number system. In 1820, Thomas de Colmar launched the mechanical calculator industry when he released his simplified arithmometer, which was the first calculating machine strong enough and reliable enough to be used daily in an office environment. Charles Babbage started the design of the first "automatic mechanical calculator", his Difference Engine, in
Digital transformation the development of the first electromechanical computer from his discovery of the automatic computing relays as well as the term 'digital'. The first electronic computer was introduced by John Atanasoff in 1939. The process of digitalization thereafter accelerated, with the development of personal computers such as the Simon in 1950, Apple II in 1977 and IBM PC in 1981. With the introduction of the World Wide Web, the scope, dimension, scale, speed as well as effects of digitalization fundamentally changed, resulting in the increased pressure on the societal transformation process. In 2000, digitalization began to be used more widely as
