The life of alan turing

Alan Mathison Turing, OBE, FRS was a British mathematician, logician, cryptanalyst, philosopher, pioneering computer scientist, mathematical biologist, and marathon and ultra distance runner.He was highly influential in the development of computer science, providing a formalisation of the concepts of "algorithm" and "computation" with the Turing machine, which can be considered a model of a general purpose computer. Turing is widely considered to be the father of theoretical computer science and artificial intelligence.


The machine you are looking at. It might be a PC, laptop, tablet or smartphone — they are all based on the same principle, though with different forms of input and output.

These machines can process photographs, set up your wireless, send emails, set up secure encipherment for on-line payments, do typography, refresh the screen, monitor the keyboard, manage the performance of all these in synchrony... and do all of these things through a single principle: reading programs placed in the internal storage.

Everyone knows: computers come into every aspect of modern life.

But the meaning of the word 'computer' has changed in time. In the 1930s and 1940s 'a computer' still meant a person doing calculations. There is a nice historical example of this usage here. So to indicate a machine doing calculations you would say 'automatic computer'. In the 1960s people still talked about the digital computer as opposed to the analog computer.

But nowadays, it is better to reserve the word 'computer' for the type of machine which has swept everything else away in its path: the computer on which you are reading this page, the digital computer with 'internally stored modifiable program.'
