The Z3 was a German electromechanical computer designed by Konrad Zuse in 1938, and completed in 1941. It was the world's first working programmable , fully automatic digital computer . [ 3 ] The Z3 was built with 2,600 relays , implementing a 22- bit word length that operated at a clock frequency of about 5–10 Hz . [ 1 ]
In 1941, he improved on the basic Z2 machine, and built the Z3. On 12 May 1941 Zuse presented the Z3, built in his workshop, to the public. [23]: 425 [28] The Z3 was a binary 22-bit floating-point calculator featuring programmability with loops but without conditional jumps, with memory and a calculation unit based on telephone relays. The ...

The Z1 was a motor-driven mechanical computer designed by German inventor Konrad Zuse from 1936 to 1937, which he built in his parents' home from 1936 to 1938. [1] [2] It was a binary, electrically driven, mechanical calculator, with limited programmability, reading instructions from punched celluloid film.
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 ...
Babbage was never able to complete construction of any of his machines due to conflicts with his chief engineer and inadequate funding. [7] [8] It was not until 1941 that Konrad Zuse built the first general-purpose computer, Z3, more than a century after Babbage had proposed the pioneering analytical engine in 1837. [3]
z3 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 .
It was designed by Howard Aiken and his team, financed and built by IBM—it became the second program-controlled machine (after Konrad Zuse's). The whole machine was 51 feet (16 m) long, weighed 5 (short) tons (4.5 tonnes), and incorporated 750,000 parts.
