Charles Babbage KH FRS Babbage in 1860 Born (1791-12-26) 26 December 1791 London, England Died 18 October 1871 (1871-10-18) (aged 79) Marylebone, London ...
The Z3 was built with 2000 relays, implementing a 22-bit word length that operated at a clock frequency of about 5–10 Hz. [75] Program code and data were stored on punched film . It was quite similar to modern machines in some respects, pioneering numerous advances such as floating-point numbers .
[25] During her work with Babbage, Ada Lovelace became the designer of the first computer algorithm, which could compute Bernoulli numbers, [26] although this is arguable as Charles was the first to design the difference engine and consequently its corresponding difference based algorithms, making him the first computer algorithm designer.
Realistic humanoid automata were built by craftsman from many civilizations, including Yan Shi, [19] Hero of Alexandria, [20] Al-Jazari, [21] Haroun al-Rashid, [22] Jacques de Vaucanson, [23] [24] Leonardo Torres y Quevedo, [25] Pierre Jaquet-Droz and Wolfgang von Kempelen. [26] [27] The oldest known automata were the sacred statues of ancient ...

Joseph Jennissen (1905–1977), [19] member of the "Research-Leadership" (Forschungsführung) in the Reich Air Ministry [20] acted as a government supervisor for orders of the ministry to Zuse's company ZUSE Apparatebau. [21] A further intermediary between Zuse and the Reich Air Ministry was the aerodynamicist Herbert A. Wagner. [22]
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]
The history of the personal computer as a mass-market consumer electronic device began with the microcomputer revolution of the 1970s. A personal computer is one intended for interactive individual use, as opposed to a mainframe computer where the end user's requests are filtered through operating staff, or a time-sharing system in which one large processor is shared by many individuals.
