The EDVAC as installed in Building 328 at the Ballistic Research Laboratory. 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.
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 ...

The ENIAC was limited in performance to single tasks which led to the development of the EDVAC which would become the first computer designed to perform instructions of various types. Developing computing technologies facilitated the increase in performance of computers, and subsequently has led to a variety of configurations and architecture.
Preliminary design work on the ENIAC's successor machine the EDVAC resulted in the stored program concept used in all computers today, the logical design having been promulgated in John von Neumann's First Draft of a Report on the EDVAC, a set of notes synthesized from meetings he attended at the Moore School.
ENIAC (/ ˈ ɛ n i æ k /; Electronic Numerical Integrator and Computer) [1] [2] was the first programmable, electronic, general-purpose digital computer, completed in 1945. [ 3 ] [ 4 ] Other computers had some of these features, but ENIAC was the first to have them all.
A von Neumann architecture scheme. The von Neumann architecture—also known as the von Neumann model or Princeton architecture—is a computer architecture based on the First Draft of a Report on the EDVAC, [1] written by John von Neumann in 1945, describing designs discussed with John Mauchly and J. Presper Eckert at the University of Pennsylvania's Moore School of Electrical Engineering.
By the spring of 1946, Eckert and Mauchly had procured a U.S. Army contract for the University of Pennsylvania and were already designing the EDVAC – the successor machine to the ENIAC – at the university's Moore School of Electrical Engineering. However, new university policies that would have forced Eckert and Mauchly to sign over ...
