1903-1957

Biography:

1903 He was born on 28 of december was born in Budapest(Hungary) Janos Luis Neumann.

1921 His first mathematics paper was published near his tutor.

1933 He was named professor of the University of Princeton(New Jersey, USA), place of Einstein and others mathematics emigrated from Europe.

1942 Publised a book about the application of the theory games in the economy.

1944 He gots news about the secret project ENIAC

1945 He attended to the first experiments of the nuclear bomb

1947 He writes a report about the ENIAC and an sketch of the design of a new computer that was called EDVAC (Electronic Discrete Variable Computer) and was constructed according his ideas.

1951 JOHNIAC, the computer designed personaly for Neumann runs to work in the University of Princeton.

1951-1953 He was nominated President of the American Mathematical Society. He worked in the theory of automatas.

1955 The president Eisenhower named him commissioner of US Atomic Energy

1957 He dead on 8th febrary of cancer in Washington D.C (U.S.A). Later was dedicated the Bulletin of the American Mathematical Society to his life and career. (Fuente: propia).

To 1945 the physical architecture of any computer was depending of the program in the strict more plan and for this reason the objetives of this machines are inmutables, although engineers could dare to change conections, this was a difficult task and sometimes impossible, and very expensive too. John Von Neumann suggested in 1945 an alternative to a new architecture more efficient. He was born in Budapest in 1903, Neumman offered to the humanity a lot of and many differents cientifics contributions, like the theory of games, theory of automatas, calculation of propagation of the

versátil. Nacido en Budapest en 1903, Neumann a ofrecido a la humanidad muchas y muy variadas aportaciones científicas, como la teoría de los juegos, teoría de los autómatas, cálculo de la propagación de las ondas de choque, ensayo sobre la matemática de la teoría cuántica, etc. La arquitectura de "Von Neumann" fue adoptada por todos los ordenadores desde la Segunda Guerra Mundial, dicha arquitectura hace una diferenciación del ordenador en dos partes, que son las siguientes: CPU (Unidad Central de Procesamiento): que opera sobre los datos que hay que manipular. MEMORIA: es aquí donde están guardados los datos.
Las máquinas con arquitectura Von Neumann operan al compás de ciclos definidos con precisión:

- Toma de la memoria la 1º instrucción.
- Toma de otra parte de la memoria el dato sobre el que hay que operar.
- Ejecuta la operación.
- Toma de la memoria la siguiente instrucción (en este caso la segunda)
- etc...

El primer ordenador que adoptó esta nueva arquitectura fue el Electronic Discrete Variable Computer [Ordenador Electrónico de Variable Discreta] (EDVAD). Más tarde se le unió el JOHNNIAC (de la RAND Corporation) y el MANIAC [Maniaco], el Mathematical Analyzer, Numerical Integrator and Calculator [Calculador, Integrador Numérico y Analizador Matemático.
