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.
English physicist Samuel Hunter Christie invented the Wheatstone bridge (It is named after Charles Wheatstone who popularized it). 1836: Irish priest (and later scientist) Nicholas Callan invented the transformer in Ireland. 1837: English scientist Edward Davy invented the electric relay. 1839: French scientist Edmond Becquerel discovered 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.
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.
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 ...
Cray-1 supercomputer was invented by Seymour Cray. He left Control Data in 1972 to form his own company. This machine was known as much for its horseshoe-shaped design as it was for being the first supercomputer to make vector processing practical. 85 were shipped at a cost of US$5 million each. 1976: US Commodore buys MOS Technology in a stock ...
