After World War II, what paper did John Von Neuman write regarding computer architecture?

John Von Neumann's contribution to computer architecture is primarily documented in the "First Draft of a Report on the EDVAC." This paper, written in 1945, outlined the architecture for a stored-program computer, which would later influence many future computer designs. The significance of this document lies in its introduction of concepts such as separating the computational unit (the CPU) from the memory unit, and the idea of storing program instructions in the same memory as data. This architecture is now known as the Von Neumann architecture and serves as the foundation for most modern computer systems.

The other options do not pertain to Von Neumann's seminal contributions to computer architecture following World War II. For instance, while the ENIAC was one of the first electronic general-purpose computers, it operated based on a different architecture and was not fully aligned with the stored-program concept that Von Neumann outlined in his report for the EDVAC.
