Clock calculator
In 1623 William Schickard, a German mathematician, created an automatic machine which he named ammb. It was the first in history to be built.The calculating clock could perform, through totally mechanical methods, the four elementary arithmetic operations: add, subtract, multiply and divide. The machine incorporated the principle of strips of John Napier. -
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. -
1ª progamadora de la máquina analítica
Ada Lovelance was an English mathematician and writer, chiefly known for her work on Charles Babbage's proposed mechanical general-purpose computer, the Analytical Engine. She was the first to recognise that the machine had applications beyond pure calculation, and published the first algorithm intended to be carried out by such a machine. As a result, she is sometimes regarded as the first to recognise the full potential of a "computing machine" and the first computer programmer. -
1ª Máquina analítica
It was invented by Torres Quevedo and the objective of the machine was the continuous and automatic obtention of values of polynomial functions. Being an analog machine, the variable can go through any value.Therefore, before a polynomial equation, by turning all the wheels representing the unknown, the final result will be given the values of the sum of the variable terms, when this sum coincides with the value of the second member, the wheel of the unknown will mark a root. -
Máquina Enigma
The Enigma machines were a series of electro-mechanical rotor cipher machines developed and used in the early- to mid-20th century to protect commercial, diplomatic and military communication. Enigma was invented by the German engineer Arthur Scherbius at the end of World War I. Early models were used commercially from the early 1920s, and adopted by military and government services of several countries. -
Máquina universal de turing
n computer science, 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. Alan Turing introduced the idea of such a machine in 1936–1937. -
1er microprocesador
It is a 4-bit central processing unit (CPU) released by Intel Corporation in 1971. It was the first commercially available microprocessor by Intel. The chip design started in April 1970, when Federico Faggin joined Intel, and it was completed under his leadership in January 1971. The first commercial sale of the fully operational 4004 occurred in March 1971 to Busicom Corp. -
1a tarjeta de sonido
A sound card is an internal expansion card that provides input and output of audio signals to and from a computer under control of computer programs. The term sound card is also applied to external audio interfaces used for professional audio applications.
Sound functionality can also be integrated onto the motherboard, using components similar to those found on plug-in cards.
