John Von Neumann Architecture
John Von Neumann, a computer scientist, developed many foundational concepts of computing.
Stored Memory Concept
John Von Neumann proposed an architecture that used two key ideas:
- Using binary numbering to build a computer.
- Storing both instructions and the related data internally within the machine.
This architecture is known as the Stored Program Concept. Many modern computers still operate on this principle today.
Binary numbering consists of only two digits — 0 and 1, where:
- 0 represents off
- 1 represents on
This reflects the state of any electronic circuit, which can exist in either of these two forms.
The Stored Program Concept was a major breakthrough in the development of modern computers because programs and data could be loaded into a storage device. This eliminated the need to manually change wires and switches before running each application.
