EDVAC (Electronic Discrete Variable Automatic Computer) was one of the earliest electronic computers. It was built by Moore School of Electrical Engineering at the University of Pennsylvania . [ 1 ] [ 2 ] : 626–628 Along with ORDVAC , it was a successor to the ENIAC .
Mauchly persuaded the United States Census Bureau to order an "EDVAC II" computer – a model that was soon renamed UNIVAC – receiving a contract in 1948 that called for having the machine ready for the 1950 census. Eckert hired a staff that included a number of the engineers from the Moore School, and the company launched an ambitious ...
John William Mauchly (/ ˈ m ɔː k l i / MAWK-lee; August 30, 1907 – January 8, 1980) was an American physicist who, along with J. Presper Eckert, designed ENIAC, the first general-purpose electronic digital computer, as well as EDVAC, BINAC and UNIVAC I, the first commercial computer made in the United States.
Also worked on BINAC (1949), EDVAC (1949), UNIVAC (1951) with Grace Hopper and Jean Bartik, to develop early stored program computers. 1958 McCarthy, John: Invented LISP, a functional programming language. 1956, 2012 McCluskey, Edward J.
EDVAC, conceived in June 1945 in First Draft of a Report on the EDVAC, but not delivered until August 1949. It began actual operation (on a limited basis) in 1951. BINAC, delivered to a customer on 22 August 1949. It worked at the factory but there is disagreement about whether or not it worked satisfactorily after being delivered.
Eckert, a co-inventor of the ENIAC, discusses its development at the University of Pennsylvania's Moore School of Electrical Engineering; describes difficulties in securing patent rights for the ENIAC and the problems posed by the circulation of John von Neumann's 1945 First Draft of the Report on EDVAC, which placed the ENIAC inventions in the ...
EDVAC: 1951 1 The successor to ENIAC, and also built by the University of Pennsylvania's Moore School of Electrical Engineering for the U.S. Army's Ballistic Research Laboratory. One of the first stored-program computers to be designed, but its entry into service was delayed. EDVAC's design influenced a number of other computers.
Use of a delay line for a computer memory was invented by J. Presper Eckert in the mid-1940s for use in computers such as the EDVAC and the UNIVAC I. Eckert and John Mauchly applied for a patent for a delay-line memory system on October 31, 1947; the patent was issued in 1953. [1]
