EDVAC and ENIAC Computers

  • Gerard O’Regan


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. It was completed in 1946 and remained in use until 1955. The EDVAC (Electronic Discrete Variable Automatic Computer) was the successor to ENIAC, and it was one of the earliest stored-program computers, with the program instructions held in memory.
