EDVAC był binarnym komputerem szeregowym o 44-bitowym słowie wyrównanym do 48 cykli. Pamięć operacyjna miała rozmiar 1024 słów. Bity były kodowane jako puls, oznaczający jedynkę, oraz brak pulsu, czyli zero.
EDVAC, which stands for "Electronic Discrete Variable Automatic Computer," was another significant milestone in the development of early computers. It was designed as an improvement over ENIAC's limitations, particularly its lack of stored-program capability.
EDVAC (Electronic Discrete Variable Automatic Computer) was one of the earliest electronic computers. It was built by Moore School of Electrical Engineering, Pennsylvania. [1] [2]: 626–628 Along with ORDVAC, it was a successor to the ENIAC. Unlike ENIAC, it was binary rather than decimal, and was designed to be a stored-program computer.
EDVAC and the First Draft Abstract: This chapter contains sections titled: Rethinking ENIAC, Collaborative Work toward EDVAC, Progress on EDVAC, What the First Draft Described, A Gradual Counter-Reformation
The chapter “Global Overview of Early Digital Computers (Tables)” gives an overview of the first (mechanical) relay and (electronic) vacuum tube computers. These are presented in alphabetical order and (in abbreviated form) in chronological order...
This chapter charts the rapid evolution of thinking about programming and computer architecture among members of the ENIAC team from 1944 onward, as what is usually called the “stored program concept” was formulated with John von Neumann and presented in the “First Draft of a Report on the EDVAC.”
The Electronic Numerical Integrator and Computer (ENIAC) was one of the first general-purpose electronic digital computers, and it was used to integrate ballistic equations and to calculate the trajectories of naval shells (Fig. 23.1).
