First computer, Z1
First fully electro-mechanical machine, the mechanical components gave enough problems. The Z were manufactured by the German Konrad Zuse, whose work was belittled for having been produced in Germany during World War II -
Period: to
1º generation
The computers of the first Generation used bulbs to process information. The operators entered the data and programs in special code by means of punched cards. The internal storage was achieved with a drum that rotated rapidly, on which a reading / writing device placed magnetic marks. Those bulbous computers were much larger and generated more heat than contemporary models. -

Z2, after Z1 and behind Z3.
The Z2 computer, created by Konrad Zuse between 1938 and 1939, was designed from the Z1, since creating a mechanical machine presented some difficulties, and telephone relays were added to it. -
Z3
The Z3 computer, created by Konrad Zuse in 1941, was the first programmable and fully automatic machine, characteristics used to define a computer.
The Z3, of electromechanical technology, was built with 2300 relays, had a clock frequency of 5 Hz, and a word length of 22 bits.
The original Z3 was destroyed in 1943 during a bombing in Berlin. A fully functional replica was built during the 60s by the company of creator Zuse KG and is on permanent display at the Deutsches Museum. -
ENIAC
1944 ENIAC. Considered until a few years ago as the first digital computer in history. It was no a production model, but an experimental machine. No was it programmable in the real sense. It is a great machine that occupied everything in the university. Built with 18,000 tons of vacuum, consuming several electric power and weighing a few tons. He was able to make five thousand sums per second. It was done by a team of engineers and scientists headed by John W. Mauchly and Presper Eckerk. -
Z4
Designed by the German engineer Konrad Zuse and built by his company Zuse KG, this computer completely redesigned after missing the plans and pieces of the previous Z during the allied bombing of Berlin. It was the first machine to be sold commercially in 1950. -
EDVAC
1949 EDVAC. Second programable computer. It was also a laboratory prototype, but it already included in its design the central ideas that make up current computers. -
IBM 701
The IBM 701 was the first of a series of computers of this company, which later became number one, by its sales volume.
IBM 701 operator console
IBM 701, known as the "Defense Calculator" as it developed, was announced to the public on April 29, 1952 and was IBM's first commercial scientific computer.1 Its siblings in office computing were IBM 702 and IBM 650. During Four years of production, 20 units were sold.2 -
BRAINIAC, not a computer
1953 brainiak. To enter the data, these teams used punched cards, which had been invented in the years of the industrial revolution (late eighteenth century) by the French Joseph Marie Jacquard and perfected by the American Herman Hollerith in 1890. The IBM 701 was the first of a long series of computers of this company, that later would become number one, by its volume of sales. -
IBM, more computers.
1954 - IBM continued with other models, which incorporated a mass storage mechanism called magnetic drum, which over the years evolved and became the magnetic disk. -
Zuse Z22
1955 - Zuse Z22. The first Konrad Zuse computer taking advantage of the vacuum tubes.
