Quite a few builders of ENIAC saw its complications. They invented a way to to get a computer to remember the things they had instructed it, along with a way to vary what it remembered. This is known as "stored system architecture" or von Neumann architecture. John von Neumann discussed this structure in the paper Initial Draft of a Report to the EDVAC, dispersed in 1945. Many tasks to develop computers according to the stored-application architecture begun close to this time.
