Electronic Discrete Sequential Automatic Computer
(EDSAC, often "Electronic Delay Storage Automatic Computer") Based upon the EDVAC (Electronic Discrete Variable Automatic Computer) designed in 1945, the EDSAC was completed in 1949 at the University of Cambridge Mathematical Laboratory in England. The EDSAC performed its first calculation on 1949-05-06. EDSAC was considered to be the first computer to store programs. It ceased to exist in about 1951.
