Von neumann architecture: The Von Neumann architecture

The Von Neumann architecture, named after the mathematician and physicist John von Neumann, is a foundational concept in computer science that has shaped modern computing. This architecture is the basis for most modern computers and has been the cornerstone of computing for over seven decades. Von Neumann architecture is a computer design where instructions and data are stored in the same memory space. This means the CPU fetches both instructions and data from the same memory, using the same pathways. The von Neumann architecture serves as the foundation for most modern computers. In this section, we briefly characterize the architecture’s major components. Von Neumann architecture is defined as the fundamental computer architecture characterized by a centralized control unit within the CPU, a separate primary memory for storing both instructions and data, and an arithmetic and logic unit (ALU) for performing operations on operands, with a built-in addressing mechanism to facilitate instruction execution.
