Charles Babbage is awarded to the be computers father. He made the first machine as he called Different Engine. The existing technique at that time did not allowed him to Build a machine such as Babagge meant to build.

In 1836, Babagge planned to build a new "computer" he called it "An analytical engine". It was the groundwork to the first general digital computer, memory and I/O units. It should work with holecards. Not even this one was ever built.

During the Second World War, several different computers were built. Some of then was not a computer, but a machine build only to do just one thing: de code cipher.

ENIAC was build in 1945 by electronic valves, 18 000 pieces and tested for the first time in December 1945 and the result were published in

February 1946.The first job ENIAC had was to calculations for the Los Alamos project. ENIAC had some large disadvantage, too little memory capacity, to big (30 meters long, 3 meters high and 90 cm deep.) and so on.

The Englishmen built the first computer ,with its own program stored in its memory, EDSAC. In 1949, they demonstrated it for the first time ever for the public.

The electronic valves were replaced by be semiconductors, developed at Bells laboratory. It was made in germanium with one large problem it had no resistance against heat.

1971 the first microprocessor was made by the Intel corporation. In 1965, Gordon Moore presented the so-called Moore´s law.
