von Neumann architecture
computer architecture using a common memory bus and address space for instructions and data
AI overview
Von Neumann architecture is a design for computers that uses a single shared memory to store both the instructions that tell the computer what to do and the data it operates on. This design matters because it became the foundational approach for most computers we use today, making them simpler to design and more flexible in how they can be programmed.

A von Neumann architecture scheme
The von Neumann architecture—also known as the von Neumann model or Princeton architecture—is a computer architecture based on the First Draft of a Report on the EDVAC, written by John von Neumann in 1945, describing designs discussed with John Mauchly and J. Presper Eckert at the University of Pennsylvania's Moore School of Electrical Engineering. The document describes a design architecture for an electronic digital computer made of "organs" that were later understood to have these components:
