Wilhem Schickard-Reloj calculado
The calculating clock could realize, across totally mechanical methods, four arithmetical elementary operations: to add up, to remain, to multiply and to divide. The machine was incorporating the beginning of regletas of John Napier. -
Blaise Pascal- Pascalina
Pascal's calculator (also known as the arithmetic machine or Pascaline) is a mechanical calculator invented by Blaise Pascal in the early 17th century. Pascal was led to develop a calculator by the laborious arithmetical calculations required by his father's work as supervisor of taxes in Rouen. He designed the machine to add and subtract two numbers directly and to perform multiplication and division through repeated addition or subtraction. -
Ada Lovelace- 1ª programadora de la máquina analítica
The Analytical Engine was a proposed mechanical general-purpose computer designed by English mathematician and computer pioneer Charles Babbage. It was first described in 1837 as the successor to Babbage's difference engine, a design for a mechanical computer. The logical structure of the Analytical Engine was essentially the same as that which has dominated computer design in the electronic era. -
Leonardo Torres Quevedo- 1ª Máquina Algebraica
The machine took as an object the obtaining of constant and automatic form of values of polinominal functions.Since it was a question of an analogical machine,the variable can cross any value (not only discreet prearranged values).Before a polinominal equation,on having turned all the representative wheels of the mystery,the final result is giving the values of the sum of the variable terms,when this one adds up coincide with the value of the second member, the wheel of the mystery marks a root. -
Ejercito aleman-Máquina enigma
The machine Crux used as most of the German communications during the war had a complex functioning. It was based on five rotors that were changing whenever a key was touched, so that every letter of the alphabet was offering the highest number of possibilities. The German Army was complicating more the things changing the position of the rotors once a month. The German controls of the epoch saw to Crux as undecipherable. -
Alan Turing- Máquina Universal de Turing
A universal Turing machine is a Turing machine that can simulate an arbitrary Turing machine on arbitrary input. The universal machine essentially achieves this by reading both the description of the machine to be simulated as well as the input thereof from its own tape. This principle is considered to be the origin of the idea of a stored-program computer used by John von Neumann in 1946 for the "Electronic Computing Instrument" that now bears von Neumann's name: the von Neumann architecture. -
Sophie Wilson Lenguaje de programación: Basic
As a way to facilitate the programming in computers to students (and teachers) that were not of sciences. In that epoch, almost the whole use of the computers was needing to codify made made-to-measure software, with which persons still had him restricted with formation as scientists and mathematicians. BASIC originally was developed as a tool of education. The language and his variants managed to be widely available in the microcomputers at the end of the year 1970 and in the year 1980.
