Von Neuman Architecture
The Von Neumann architecture is a foundational concept for modern computer design, named after the mathematician and physicist John Von Neumann, who detailed the structure in 1945. This architecture describes a system where a computer is comprised of four main parts: the arithmetic logic unit (ALU), the control unit, memory, and input/output mechanisms.
Key characteristics of the Von Neumann architecture include:
1.Stored Program Concept: Both program instructions and data
are stored in the same memory. This was a significant departure from earlier
computing machines where instructions were hardcoded or manually set.
3.Control Unit: This extracts instructions from memory and
decodes and executes them, calling on the ALU when necessary.
This architecture is the foundation for the design of most digital computers and the field of computer science.
