Who described the Von Neumann architecture?

The Von Neumann architecture was described by John von Neumann, a mathematician and physicist, in the 1940s. This architecture is a foundational model for designing computers and includes components such as a central processing unit (CPU), memory, and input/output mechanisms. One of the key features of the Von Neumann architecture is that it uses a single memory space to store both data and instructions, making it more efficient for processing tasks as it eliminates the need for complex data handling systems.

In this model, instructions are fetched from memory, decoded, and executed in a sequential manner, which reflects how modern computers operate today. John von Neumann's contributions to computer science were instrumental in shaping how digital computers were developed and are still relevant in discussions about computer architecture. Understanding this concept is critical for anyone studying computer science.
