Von Neumann architecture, also known as the von Neumann model, is a computer architecture framework proposed by mathematician and physicist John von Neumann in 1945. This architecture forms the basis for most modern computers and defines the structure and functioning of a general-purpose computer system. The key components of von Neumann architecture include:
The key characteristics and principles of von Neumann architecture include:
While von Neumann architecture has been highly influential and forms the basis for most computers, it is not without limitations. One notable limitation is the von Neumann bottleneck, which refers to the limited data transfer rate between the CPU and memory due to the use of a single bus for both instructions and data. Despite its limitations, von Neumann architecture remains a fundamental and widely used model for designing and understanding computer systems.
