Techopedia Explains Electronic Discrete Variable Automatic Computer

EDVAC was designed in 1944 and built in the 1940s, before being installed in the U.S. Army’s Ballistics Research Laboratory in Maryland in August of 1940.

As a binary serial computer, EDVAC processed mathematical operations with a serial memory capacity of roughly 5.5 kB. EDVAC used magnetic tape as a data media and could run over 20 hours a day.

EDVAC was replaced in 1961 by the Ballistic Research Laboratories Electronic Scientific Computer (BRLESC) which had a larger memory and faster response times.
