Zuse, however, did not know of Shannon's work and developed the groundwork independently [11]: 149 for his first computer Z1, which he designed and built from 1935 to 1938. Zuse's coworker Helmut Schreyer built an electronic digital experimental model of a computer using 100 vacuum tubes [29] in 1942, but it was lost at the end of the war.
Plankalkül (German pronunciation: [ˈplaːnkalkyːl]) is a programming language designed for engineering purposes by Konrad Zuse between 1942 and 1945. It was the first high-level programming language to be designed for a computer.
Konrad Zuse was born in Berlin on 22 June 1910. [21] In 1912, his family moved to East Prussian Braunsberg (now Braniewo in Poland), where his father was a postal clerk.Zuse attended the Collegium Hosianum in Braunsberg, and in 1923, the family moved to Hoyerswerda, where he passed his Abitur in 1928, qualifying him to enter university.
The Z4 was arguably the world's first commercial digital computer, and is the oldest surviving programmable computer. [1]: 1028 It was designed, and manufactured by early computer scientist Konrad Zuse's company Zuse Apparatebau, for an order placed by Henschel & Son, in 1942; though only partially assembled in Berlin, then completed in Göttingen in the Third Reich in April 1945, [2] but not ...
The Z22 was the seventh computer model Konrad Zuse developed (the first six being the Z1, Z2, Z3, Z4, Z5 and Z11, respectively).One of the early commercial computers, the Z22's design was finished about 1955.
The Zuse Z25 was a program-controlled electronic computer using transistors developed by Zuse KG in Bad Hersfeld and put into production in 1963. The word length was 18 bits, [1] though it could also process double-word lengths for accuracy up to 10 decimal digits. The addressable space was 32768 words.
The Z2 was an electromechanical (mechanical and relay-based) digital computer that was completed by Konrad Zuse in 1940. [1] [2] [3] It was an improvement on the Z1 Zuse built in his parents' home, which used the same mechanical memory. In the Z2, he replaced the arithmetic and control logic with 600 electrical relay circuits, weighing over 600 ...
