Charles Babbage
He was a mathematician born in Teignmouth England on December 26, 1791. Specialist in the area of mathematics and computation, he was known for designing and creating the differential machine and designing the analytical machine to generate Computer programs that represent the bases for the creation of computers. He died on October 18, 1871, in Marylebone, United Kingdom.
One of his more notable works was the Analytical machine. -
Enigma Machine
The Enigma Machine was an electromechanical device, that had an electrical and a mechanical part, it consisted of a series of keys, with the letters of the alphabet, like a typewriter. The Enigma Machine was created by the German engineer Arthur Scherbius. In 1930 the German military use it. -
Z1 computer
In 1936 Konrad Zuse designed his first computer, which was called V1, but after the WW II the name was changed into Z1.
The Z1 included a total of 20,000 pieces and weighed around 1 ton. Was the first programmable computer in history and that is why it is considered by many as the first computer. The Z1 consisted of six units: a control unit, an arithmetic unit, input and output, a memory, a memory selector and a tape reader.

BOMBE
BOMBE was the name of an electro-mechanical machine, developed during World War II by Alan Turing and Gordon Welchman. It was used to help decrypting Nazi ENIGMA-based military communications during World War II. Later The US Navy and US Army produced their own machines for same functional specification, but they were engineered differently. -
Hewlett-Packard is founded
The company was founded in 1939 by William Hewlett and David Packard in a Palo Alto, California garage. Their first product, the HP 200A Audio Oscillator, became a popular piece of test equipment for engineers. The Audio Oscillator was so popular that even Walt Disney Pictures ordered eight of the 200B model.

The Complex Number Calculator (CNC)
Bell Telephone Laboratories completes this calculator who was originally designed by the scientist George Stibitz, in 1939. In 1940, George Stibitz demonstrates the CNC at the American Mathematical Society conference in which he perform calculations remotely using a Teletype terminal.
The complex number calculator was a machine capable of adding, subtracting, multiplying, and dividing complex numbers. -
Computer ABC-The first digital computer
The Atanasoff-Berry ABC computer was designed and built by John Vincent Atanasoff and a student named Cliff Berry between 1937 and 1942 at Iowa State University.
ABC was a computer designed to solve systems of linear algebraic equations and it was able to solve systems that included up to 29 unknown variables. The replica of these computers is currently in the Computer History Museum.

Colossus
Colossus fue la primera computadora eléctrica programable. Fue diseñada por Tommy Flowers (un ingeniero de la Post Office Research Station) en 1943. Fue utilizada por el gobierno británico para tratar de romper el código de los mensajes encriptados enviados por los alemanes durante la segunda guerra mundial.
Una réplica de la computadora Colossus fue construida en el 2007 y está en exhibición en el Museo Nacional de la Computación -
Harvard Mark I
IBM Automatic Sequence Controlled Calculator (Harvard Mark I), was the first electromechanical computer built at IBM and was sent to Harvard in 1944. The project between IBM and Howard Aiken (Harvard physics professor) began in 1939, but was officially presented to the public in 1944. Aiken was the one who designed it and it was built by IBM. The machine had a fifty foot long and used 3,500 relays. The Mark 1 produced mathematical tables. -
The 1st general-purpose computer: ENIAC
ENIAC was built at the University of Pennsylvania in 1946. ENIAC was the first fully functional, general purpose digital computer to be designed. -
EDSAC
EDSAC was the first practical stored program computer to provide a regular computing service. The computer was built at the Cambridge University. The EDSAC project was led by a professor of the Cambridge school and the director of the Cambridge Computation Laboratory, Maurice Wilkes, on 1949

Digital Equipment Corporation (DEC) is founded
Digital Equipment Corporation, was a US company that was founded in 1957 by Kenneth Olsen and Harlan Anderson, but was later acquired by Compaq in 1998, (Compaq was acquired by Hewlett-Packard in 2002).
This Digital company was the creator of the so-called minicomputers.
Their PDP and VAX products were the most popular minicomputers

Z3 computer
The Z3, a computer built by German engineer Konrad Zuse, the first programmable and fully automatic computer. The Z3 machine had two thousand relays and could perform really complex calculations. The Z3 was used for aerodynamic calculations but was destroyed in a bombing raid on Berlin in 1943, but Zuse do a reconstruction of these computer in 1960, which is currently on display at the Deutsches Museum in Munich.

3C DDP-116
This was a computer designed by the engineer Gardner Hendrie for Computer Control Corporation (CCC), on 1965. It was the world's first commercial 16 bit minicomputer and 172 systems were sold. The basic computer cost $28,500. This computer has a speed of 294,118 sec, a memory Size of 4k words and a memory Width of 16 bit -
Microsoft
Microsoft Corporation es una compañía tecnológica multinacional. Desarrolla, manufactura, licencia y provee soporte de software para computadores personales, servidores, dispositivos electrónicos y servicios. Microsoft fue fundada por Paul Allen y Bill Gates el 4 de abril de 1975 para el Altair 8800 (un microordenador diseñado en 1974)

Apple I
In 1976 Steve Wozniak created Apple's first computer, called Apple I and Steve Jobs was responsible for selling it for $ 666.66.
These are some characteristics of the Apple I: 4 Kb of RAM that could be expanded to 8 Kb; ports for keyboard and for any type of monitor; 256 Kb ROM memory; It supported graphics of 40 × 24 characters.

WIFI
Hedy Lamarr was an actress who developed a system of detection of remote-controlled torpedoes inspired by a musical principle.
This system is the precursor of the technology that is used today for wireless communications of GPS systems, wifi and mobile phones.
Was used for the first time by the United States, but it was until 1980 when its creation was applied to civil engineering. -
The 1st Smartphone
The first smartphone was the IBM Simon, created in 1992 and distributed by the USA between August of 1994 and February of 1995, it had a a user interface absent of physical buttons, touch screen, predictive text, calendar, SMS functions, email, etc. It was built by a business union between the International Business Machines Corporation and the BellSouth Cellular company. -
Differential Machine - First mechanical computer
In 1821, the inventor and mathematician Charles Babbage, began the development (Design) of the Differential Machine, but it was until 2002 that the first difference machine was successfully built in London, England.
This computer is considered the first machine capable of calculating polynomial functions used in general mathematical and engineering applications.
