The first Z1 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 the Second World War. -

ENIAC Considered until a few years ago as the first electronic digital computer in history.3 It was not a production model, but an experimental machine. Nor was it programmable in the current sense. It was a huge device that occupied a basement in the university. Built with 18,000 vacuum tubes, it consumed several kW of electrical power and weighed a few tons. He was able to make five thousand sums per second. It was made by a team of engineers and scientists headed by Drs. -

he Z4 was completed, 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. Second programmable computer. It was also a laboratory prototype, but it already included in its design the central ideas that make up current computers. -

UNIVAC I. Considered the first commercial computer to be sold, although it was overtaken by the British Feranti Mark I for a few months, and never took into account the Z4 that came forward almost a year. Doctors Mauchly and Eckert founded Universal Computer Company (Univac), and their first product was this machine. The first client was the United States Census Bureau. -

to enter the data
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 the number one, by its volume of sales. -
Period: to
continuous with other models
IBM continued with other models, which incorporated a mass storage mechanism called a magnetic drum, which over the years would evolve and become the magnetic disk. -
Period: to
the first computer of Konrad Zuse
Zuse Z22. The first Konrad Zuse computer taking advantage of vacuum tubes.
