Their system used the binary arithmetic system of 1s and 0s commonly used in today’s computers as well as a memory drum that stored data in a method similar to the storage technique used in modern memory chips.
Although it was the first large-scale machine to do routine calculations in a production environment, the ENIAC was not the first electronic computer.
Unlike modern computers, which use microprocessors composed of thousands or millions of transistors, ENIAC used vacuum tubes to process data.

Mauchly may have continued to draw ideas from <<<bb>>bb>bb>>>bb>b>bb>>bb>bb>>>>Atanasoffb>bb>>bb>bb>>>bb>b>bb>>bb>bb>>>>'s further reflections on electronic computing, but it was ultimately Mauchly who, working with Eckert, designed the first general- purpose electronic computer.
Still, the ABC had been designed as a special purpose computer designed only to solve large systems of linear equations.

Originally, a "computer" (sometimes spelled "computor") was a person who performed numerical calculations under the direction of a mathematician, often with the aid of a variety of mechanical calculating devices from the abacus onward.
Computer operating systems and applications were modified to include the ability to define and access the resources of other computers on the network, such as peripheral devices, stored information, and the like, as extensions of the resources of an individual computer.

J. Presper Eckert - Wikipedia, the free encyclopedia

Together with John W. Mauchly he constructed the ENIAC, sometimes considered the first electronic digital computer, from 1941-1945 (but see John Vincent <<<bb>>bb>bb>>>bb>b>bb>>bb>bb>>>>Atanasoffb>bb>>bb>bb>>>bb>b>bb>>bb>bb>>>> and <<<bb>>bb>bb>>>bb>b>bb>>bb>bb>>>>Atanasoffb>bb>>bb>bb>>>bb>b>bb>>bb>bb>>>> <bb>>Berryb>bb>> Computer for conflicting claims).
John Presper Eckert, a computer pioneer, was born April 9, 1919 in Philadelphia and died June 3, 1995 in Bryn Mawr, Pennsylvania.
Eckert and Mauchly started up the Electronic Control Company which built the Binary Automatic Computer (BINAC).

Mauchly borrowed ideas from the first electronic computer - <<<bb>>bb>bb>>>bb>b>bb>>bb>bb>>>>Atanasoffb>bb>>bb>bb>>>bb>b>bb>>bb>bb>>>> <bb>>Berryb>bb>> Computer.
ENIAC, short for Electronic Numerical Integrator And Computer, was long thought to have been the first electronic computer designed to be Turing-complete, capable of being reprogrammed by rewiring to solve a full range of computing problems.
Eckert and Mauchly took the experience they gained and founded the Eckert-Mauchly Computer Corporation, producing their first computer, BINAC, in 1949 before being acquired by Remington Rand in 1950 and renamed as their UNIVAC division.

Eckert assumed the task of designing a new computer system, while Mauchly conducted research into the possible uses for electronic computers.
Eckert and Mauchly were recognized with numerous honors and awards for their work, having both received the U.S. National Medal of Science in 1969 and the IEEE Computer Society Pioneer Award in 1980.

Forgotten Father of the Computer - The World and I Magazine

The reasons for the 32-year delay in the recognition of Atanasoff are mostly the dislocations caused by World War II, which sidetracked Atanasoff and <bb>>Berryb>bb>> from pursuing their computer project and to some degree kept Iowa State officials from patenting the ABC.
Although neither Atanasoff nor <bb>>Berryb>bb>> was free to devote full time to the computer prototype, it moved forward with amazing speed.
As Atanasoff and <bb>>Berryb>bb>> started work on that project in early 1940, Atanasoff took considerable ribbing from some of his less imaginative friends of the faculty.
