EDVAC

[′ed‚vak]
(computer science)
The first stored program computer, built in 1952. Derived from electron discrete variable automatic compiler.

EDVAC

(Electronic Discrete Variable Automatic Computer) The successor to ENIAC, EDVAC was designed by J. Presper Eckert and John Mauchly at the University of Pennsylvania in the 1940s. Although it was the first stored program computer, it did not become operational until 1952, two years after SEAC, which was based on EDVAC designs.

EDVAC was an arithmetic-only computer working with binary numbers rather than the decimal operations of ENIAC. It had 1K 44-bit words of delay line memory. See ENIAC, SEAC, early memories and early computers.

This conclusion was based on a good deal of study, for the field was very young, on early conversations with Perry Crawford, who had been a fellow graduate student interested in digital computation and was now the Special Devices official responsible for the ASCA contract, and on newly acquired information about the ENIAC and EDVAC.
Immediately after that visit, he had requesterd and received a copy of von Neumann's First Draft of a Report on the EDVAC [30], the influential report that gave a basic discussion of logical control and stored programming in a digital computer.
His enthusiasm for the potential of electronic computers and for the work done at the Moore School on the ENIAC and EDVAC brought to the early days of computers the participation of a brilliant mind, the expertise of a distinguished logician, and the tireless dedication of a man who was convinced that here lay the answers to some of the problems he found most interesting and important, particularly in the applications of fluid dynamics.
