when was the computer invented? and who invented it?

Answer 1

SOme would say that the abacus is a computer or at least a calucator

Answer 2

The modern stored-program electronic digital computer was invented by John von Neumann of the Institute of Advanced Study, Princeton.

The invention was based on his knowledge of a large automated electromechanical calculator (ASCC) built by Howard Aitken at Harvard in 1944, and a large electronic calculator (ENIAC) built by J. Presper Eckert and John W. Mauchly at the Moore School of Electrical Engineering, Pennsylvania, in 1946. There was an earlier electronic calculating unit (ABC) built by John V. Atanasoff and Clifford Berry at Iowa State University in 1938-41, which had influenced Eckert and Mauchly. Von Neumann is known to have met Alan Turing, so he may have known something of the electronic codebreaking engine (Colossus) built by Max Newman and Tommy Flowers at Bletchley Park, England, in 1943-44, because Turing worked there too.

The design of a unified type of general-purpose computer was described in the article "Preliminary Discussion of the Design of an Electronic Computing Instrument" by Arthur W. Burks, Hermann H. Goldstine and John von Neumann in 1946. All subsequent computers followed this design.

The first two computers completed to the new design were at Manchester, England in June 1948 by Tom Kilburn and Freddie Williams, and at Cambridge, England in May 1949 (the EDSAC) by Maurice Wilkes. The third , in America, was not finished until nearly the end of 1950.

Answer 3

That depends on who you're talking to. A working computer, or adding machine, was developed in the 1800's, but archeologists have recently discovered a machine which calculated the times of the phases of the moon, the rising and setting of the planets--it was, of all places, in a wreck in the Mediterranean. It is believed to have been created by Archimedes.

Answer 4

the gadget that I am using to "talk" to you ??? I only ask because my father's first job was as a "computer."

1840 - Charles Babbage - Analytical Engine
1930-1940's - large electromagnetical calculator
1943 - ENIAC - electromagnetic calculating machine
1945 - Alan Turing - the internally stored modifiable program

The computer of today was a compilation of lots of peoples work. But, Alan Turing's work made today's gadget possible.

Answer 5

The abacus is a computer it was invented by the chinese thousands of years ago to aid in "computing" large numbers

Answer 6

Turing machines, first described by Alan Turing in (Turing 1937), are simple abstract computational devices intended to help investigate the extent and limitations of what can be computed.

Answer 7

Alan Turing in 1945
