John w created first fully operational electronic computer?

Answer 1

1. Tommy Flowers designed the Colossus computer for Bletchley Park to crack the German High Command teletype cypher called Tunny. Ten machines were built and used from 1944 to 1945. While never used as a general-purpose electronic digital computer analysis of its design later showed it to have full general -purpose capability. The British kept two of these machines running from 1945 into the 1970s to break Soviet teletype cyphers, so they were not declassified until the 1980s and do not appear in most books on the history of computers.
2. J. Presper Eckert and John Mauchly designed the ENIAC for the US Army Ballistics Research Laboratory. One machine was built in 1945. It was designed to be general-purpose and its first real program was to simulate Edward Teller's original hydrogen bomb design called the Classical Super. This job took 2 months to run (December 1945 and January 1946), after which ENIAC was declassified and demonstrated to the public in February 1946 making it the first general-purpose electronic digital computer known to the public.

Answer 2

J. Presper Eckert and John Mauchly designed and built the first operational electronic digital computer, ENIAC (Electronic Numerical Integrator And Computer) at the University of Pennsylvania in Philadelphia. They developed it for the U.S. Army. Started in 1943, it took 200,000 man-hours and nearly a half million dollars to complete two years later.

If you mean a digital computer and not an analog computer it was probably one of these two that both became operational in early 1942:

• ABC: special purpose, electronic, not programmable. John Vincent Atanasoff.
• Harvard Mark I: general purpose, electromechanical, programmed on punched tape. Howard Aiken.

ENIAC was not operational until late 1945.

On the other hand, analog computers of various types had been operational since the 1920s.

Answer 3

The first fully operational electronic computer was called ENIAC or Electronic Numerical Integrator And Computer. It was built at the University of Pennsylvania by J. Presper Eckert and John Mauchly for the Department of Defense. It was very large and cost almost $500,000 to build.

Answer 4

Dr. John W Mauchly and j. Presper Ekert Jr.

Answer 5

Him along with J. Presper Eckert created the ENIAC

Answer 6

It depends on what you mean by computer; but a good candidate is the colossus code breaking machine built by Tommy Flowers in 1943.
