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 ...
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.
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.

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.
Development of programming language Pascal begun, continued in Switzerland from 1968 to 1971. [25] Based on ALGOL. Developed by Niklaus Wirth as a pedagogic tool. 1967: US The floppy disk is invented at IBM under the direction of Alan Shugart, for use as a microprogram load device for the System/370 and peripheral controllers. Aug 1967: UK
In April 1947, Eckert and Mauchly created the tentative instruction code, C-1, for their potential successor model to the EDVAC, which was the earliest document on the programming of an electronic digital computer intended for commercial use. A month later, they renamed their next project to "the UNIVAC."
