Ferranti mark 1 alan turing biography

Turing studied mathematics at Cambridge University, and subsequently taught there, working in the burgeoning world of quantum mechanics. It was at Cambridge that he developed the proof which states that automatic computation cannot solve all mathematical problems. This concept, also known as the Turing machine, is considered the basis for the modern theory of computation.

He began to work secretly part-time for the British cryptanalytic department, the Government Code and Cypher School. On the outbreak of war he took up full-time work at its headquarters, Bletchley Park. Here he played a vital role in deciphering the messages encrypted by the German Enigma machine, which provided vital intelligence for the Allies.

He took the lead in a team that designed a machine known as a bombe that successfully decoded German messages. He became a well-known and rather eccentric figure at Bletchley. The Pilot ACE had thermionic valves vacuum tubesand used mercury delay lines for its main memory. Each of the 12 delay lines could store 32 instructions or data words of 32 bits.

This ran its first program on May 10,at which time it was the fastest computer in the world with a clock speed of 1MHz. Yunchul Kim Hello, world! Hello, world! It uses acoustic signals to store data. A codified auditory signal feedback circulates in a closed system consisting of a computer, a loudspeaker, meters of copper tubing and a microphone.

In addition to this a screen shows a visual representation of the information traveling around the system. If a participant makes noises near the installation or hits the copper piping it interferes with the audio signal loop. There is some instability in the system. If you go up to the sculpture you can hear the sounds every sign of the ASCII code has its own sine wave frequency thus translating it in an acoustic signal travelling through the copper piping.

But a loud noise in the exhibition space or a vibrational disturbance from passing traffic or low frequency rumble effects the lettering on the screen and the text and Hello, World! While in Manchester, Alan Turing writes the programming manual for the Ferranti Mark I, an early British digital computer, and trains staff as programmers.

The Mark I no longer saves data and programs on punched tape, but instead uses a new system of a line of dots on a Williams tube display. Its storage capacity, which was huge for the time, gave users plenty of scope for new experiments, such as initial chess and draughts programs as well as digital musical compositions. The penultimate topic in our Alan Turing year includes a display of the interactive installation Love Letters by David Link, who has created a fully functioning replica of the Ferranti Mark I using original components.

The machine program generates personal love letters with the help of an algorithm. Christopher Strachey originally wrote the code for the love letters program in the s. No longer available online. The acronym M. One of the very first software developers, Christopher Stracheyhad used the built-in random generator of the Ferranti Mark Ithe first industrially produced computer of this kind, to generate texts that are intended to express and arouse emotions.

Alan Turing dies at not quite 42 years of age, after eating a poisoned apple, as in the fairytale. His incredibly influential body of work remains, and has left its mark on the discipline known as computer science today. The tenth and final topic looks back on the Alan Turing year of For twelve months, Turing has been the focus of international conferences, events and exhibitions, which the HNF now reviews.

The Turing Award is now the biggest of its kind in the world of computer science. Alan Turing at the time of his election to a Fellowship of the Royal Society. It had 48 operation codes ; instructions contained a 6-bit op-code, a 3-bit B-line selection, and a 9-bit memory address. Two bits were apparently unused.

Note: There are inconsistencies between sources as to some of the details; take everything here with a grain of salt! It also supported only signed numbers, instead of both signed and un-signed. In NovemberDr. Dietrich Prinz wrote one of the earliest computer games, a chess-playing program for the Manchester Ferranti Mark 1 computer. The limitation of the Mark 1 computer did not allow for a whole game of chess to be programmed.

Prinz could only program mate-in-two chess problems. The program examined every possible move for White and Black thousands of possible moves until a solution was found, which took 15—20 minutes for easy problems but several hours in general.
