Operating System — Fundamentals, Von Neumann architecture

What is Von Neumann Architecture?

The Von Neumann architecture is a foundational design model for electronic digital computers. At its core, this architecture consists of a single processing unit, the Central Processing Unit (CPU), and a single storage structure to hold both the instructions and the data. The steps in the model generally involve fetching the instruction from memory, decoding it, executing it, and then storing the results.

While today’s computers and infrastructures have evolved significantly and have many layers of abstraction and complexity beyond the initial Von Neumann model, they still fundamentally operate on these principles.

The Von Neumann architecture breaks down the foundational structure of a computer into five primary components, each serving a distinct role:

Collectively, these five components make up the Von Neumann architecture, a fundamental model that has been at the heart of…
