A discussion of the core concepts of modern computing and their basis in history.
Dr Doron Swade offers a new analysis of the history of computing, suggesting that instead of a linear progression from one phase to the next, it is better understood as a series of separate computational functions diverging and converging.
Dr Swade goes beyond the analysis of the history of computing as moving from the Mechanical to the Electromechanical and then to the Electronic phase. Instead he argues that the history of computing is better understood as the diverging and merging of a series of streams which represent very separate computational functions or paradigms: Calculation, Automatic Computation, Information Management, Communication and the Electronic Information Age.
This is the 2013 Gresham-BSHM lecture, tracing the origins of the core concepts of modern computing.
