The Atanasoff–Berry computer (ABC) was the first automatic electronic digital computer. [1] The device was limited by the technology of the day. The ABC's priority is debated among historians of computer technology, because it was neither programmable , nor Turing-complete . [ 2 ]
ENIAC (/ ˈ ɛ n i æ k /; Electronic Numerical Integrator and Computer) [1] [2] was the first programmable, electronic, general-purpose digital computer, completed in 1945. [ 3 ] [ 4 ] Other computers had some of these features, but ENIAC was the first to have them all.
John Vincent Atanasoff OCM (October 4, 1903 – June 15, 1995) was an American physicist and inventor credited with inventing the first electronic digital computer. [1] Atanasoff invented the first electronic digital computer in the 1930s at Iowa State College (now known as Iowa State University). Challenges to his claim were resolved in 1973 ...
The UNIVAC I (Universal Automatic Computer I) was the first general-purpose electronic digital computer design for business application produced in the United States. It was designed principally by J. Presper Eckert and John Mauchly , the inventors of the ENIAC .
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] Program code was stored on ...
The ENIAC (Electronic Numerical Integrator And Computer) was the first electronic general-purpose computer, announced to the public in 1946. It was Turing-complete, [45] digital, and capable of being reprogrammed to solve a full range of computing problems. Women implemented the programming for machines like the ENIAC, and men created the hardware.
Date Place Event Feb 1950: Sweden BARK was finished in Sweden. Next to come was BESK in 1953.: Apr 1950: US SEAC (Standards Eastern Automatic Computer) demonstrated at US NBS in Washington, DC – was the first fully functional stored-program computer in the U.S.
Konrad Zuse's Z3 was the world's first working programmable, fully automatic computer, with binary digital arithmetic logic, but it lacked the conditional branching of a Turing machine. On 12 May 1941, the Z3 was successfully presented to an audience of scientists of the Deutsche Versuchsanstalt für Luftfahrt ("German Laboratory for Aviation ...
