The Von Neumann architecture is a foundational concept in computer science, named after John von Neumann, a prominent mathematician and physicist. He proposed this architecture in the mid-20th century as a design model for electronic computers. The key feature of the Von Neumann architecture is that it describes a system where a single memory space holds both program instructions and data, which allows for the sequential execution of instructions. This design greatly influenced the structure of most modern computers.

Von Neumann's contributions were pivotal because they established a framework that integrated components such as a control unit, arithmetic logic unit, memory, and input/output mechanisms, making it easier to develop software and hardware that could work together efficiently. His work laid the groundwork for future advancements in computer technology and is still relevant in understanding how computers operate today.
