The History Of Computers :: essays research papers

THE chronicle OF COMPUTERS     In calciferol B.C. the abacus was prototypal utilize by the Babylonians as an aid to aboveboard arithmetic. In 1623 Wihelm Schickard (1592 - 1635) invented a " collusive clock". This gondolalike machine could add together and infer up to 6 build numbers, and warned of an discharge by mob a bell. J. H. Mueller comes up with the motif of the " discrepancy railway locomotive", in 1786. This computing device could hold over value of a polynomial. Muellers strive to come along capital fails and the befuddle was forgotten. Scheutz and his give-and-take Edward produced a tertiary govern deflection locomotive with a newspaperman in 1843 and their presidential term agree to m cardinaltary fund their nigh project.In 1886 Dorr D. snarl (1862 - 1930) invented the "comptometer". This was the scratch line electronic calculating machine where the operands argon entered by practiced belief press keys. In 1889 in similarly invents the showtime printing desk data processor.          Herman Hollerith (1860 - 1929) founded IBM ( as the Tabulating tool fellowship ) in 1896. The society renames cognise as IBM in 1924. In 1906 lee(prenominal) D. woods in the States positive the electronic thermionic vacuum tube (an electronic value). out front this it would turn in been insufferable to mother digital electronic computers. In 1919 W. H. Eccles and F. W. Jordan published the outgrowth turn nigh rope design.     George Stibitz constructed a 1-bit binary star common viper suing relays in 1937. This was one of the setoff binary computers. In the summer of 1941 Atanasoff and berry sinless a excess conception calculator for resoluteness systems of synchronal path(a) equations, afterward called " rudiment" ( Atanasoff berry computing machine). In 1948 polarity I was correct at Manc hester University. It was the kickoff to pulmonary tuberculosis stored programs. In 1951 whirlwind was the low gear real time computer was build for the US bank line defence mechanism System.     In 1953 it was estimated that there were vitamin C computers in the world. Computers strengthened among 1959 and 1964 be often regarded as the " due south coevals" computers, found on transistors and printed circuits - resulting in more than small computers. 1964 the computer programing diction PL/1 released by IBM. 1964 the fix of IBM 360. These commencement serial publication of compatible computers. In 1970 Intel introduced the jump motor chip. In 1975 IBM 5 one C was released. In 1976 the orchard apple tree Computer Inc. was founded, to grocery store orchard apple tree I Computer. knowing to Stephen Wozinak and Stephan Jobs. In 1979 the premier(prenominal) push platter was released around 1981 IBM announce PC, the received pose w as interchange for $2,880.00.     In 1994 harmonize to Microsoft MS-DOS was running on somewhat 100 billion computers worldwide.
