"I have always taken the position that there is enough credit for everyone in the invention and development of the electronic computer" - John Atanasoff to reporters.
Professor John Atanasoff and graduate student Clifford Berry built the world's first electronic-digital computer at Iowa State University between 1939 and 1942. The Atanasoff-Berry Computer represented several innovations in computing, including a binary system of arithmetic, parallel processing, regenerative memory, and a separation of memory and computing functions.
"It was at an evening of scotch and 100 mph car rides," John Atanasoff told reporters, "when the concept came, for an electronically operated machine, that would use base-two (binary) numbers instead of the traditional base-10 numbers, condensers for memory, and a regenerative process to preclude loss of memory from electrical failure."
Atanasoff-Berry Computer
In late 1939, John Atanasoff teamed up with Clifford Berry to build a prototype. They created the first computing machine to use electricity, vacuum tubes, binary numbers and capacitors. The capacitors were in a rotating drum that held the electrical charge for the memory. The brilliant and inventive Berry, with his background in electronics and mechanical construction skills, was the ideal partner for Atanasoff. The prototype won the team a grant of $850 to build a full-scale model. They spent the next two years further improving the Atanasoff-Berry Computer. The final product was the size of a desk, weighed 700 pounds, had over 300 vacuum tubes, and contained a mile of wire. It could calculate about one operation every 15 seconds, today a computer can calculate 150 billion operations in 15 seconds. Too large to go anywhere, it remained in the basement of the physics department. The war effort prevented John Atanasoff from finishing the patent process and doing any further work on the computer. When they needed storage space in the physics building, they dismantled the Atanasoff-Berry Computer.
What else can I help you with?
The very first electronic computer components?
Vacuum tubes.
What was the name of the first electronic computer?
The first electronic computer was called the ENIAC (Electronic Numerical Integrator and Computer).
What is the fulform of ENIAC?
Electronic Numerical Integrator And Computer, was the first general-purpose electronic computer.
How is the electronic computer different from the first computer?
Electronic computer is may faster and smaller than the first developed computer. Electronic computers today uses small electronic devices and integrated circuits. Long time ago they use vacuum tubes which are huge.
Where was the first computer build at?
The answer depends on how you define a computer. Konrad Zuse built the first electronic computer at Berlin, Germany The first electronic computer in the US was built at Ames, Iowa by John Atanasoff.
