The development history of the computer

Meaning of Sistem / 360 is the meaning and the 360-degrees.

Just before the WW2, "whether it is a machine for the calculation, can not to do," he said scientists had been actively discussed. But Alan Turing (Alan Mathison Turing, England) has published a paper called "the calculation of the theoretical (Computability" ". This paper has proven to be a machine to calculate a technique called Section 4 series. Also It also mentioned to how to make the computer, was excellent paper.
When WW2 begins, the United Kingdom had been plagued by German bombing. Then British Prime Minister Churchill, whether can not decipher that enigma that the German army was using at that time, directly to Alan Turing (for top secret) has been consulted. So Alan Turing is to create a computer on their own, had been taking the statistics of the incidence of the German alphabet. And we finally reported to Churchill to decipher the message of German instruction.
The Enigma was a contrivance to typewriter, to specify the number previously, was a tool to be sent by shifting the alphabet only the number minute. On the receiving side, and set the number sent to the first, was to reproduce the telegram. In nowadays, it was not the thing was said to be very cipher.
Churchill, when there is a country of the bombing is the indifference, when finally there is the London bombing, simultaneously skip the interceptor, it was to protect the London shoot down all the German bombers.
Thanks to this, the United Kingdom and can Normandy landings is run is a joint operation of the United States, we have soon invaded in Germany. But Hitler escaped with U-boat (German submarine), it seems to have sent a secretly lifetime fled to Argentina.
Alan Turing, was asked to establish a Turing Institute in London suburbs as its reward. The field of computer science at this point has appeared in mathematics. By the way, it refers to the computer to come out in the papers of Alan Turing and the Turing machine.
WW2 is the study of the and one after another computer end starts, von Neumann of the United States of the University of Pennsylvania have created a computer called ENIAC. ENIAC was a huge machine as shown in the photograph below. The reason was because I was using a vacuum tube to all of the electronic circuit. However, the vacuum tube will be broken soon, it was not a practical thing.

The definition of the computer is a "machine that electronically calculation".
Thereafter, this definition is modified is the "machine that electronically to the calculation processing."
Mechanical calculator was there, but it was not a practical time-consuming to calculate. If the Japanese abacus was a still better.
