What is the main purpose of a bus in Jon Von Neumann's architecture?

In Jon Von Neumann's architecture, the main purpose of a bus is to connect different components of the computer system. This includes linking the central processing unit (CPU), memory, and input/output devices, allowing them to communicate and transfer data efficiently. The bus serves as a pathway for data and control signals to flow between these components, enabling the system to function cohesively.

The design is fundamental to the architecture because it supports the essential operation of executing instructions, reading data from memory, and outputting results. Without a bus system in place, the various parts of the computer would be isolated and unable to coordinate their activities, significantly hindering the machine's performance and capability. By centralizing the connections, the bus facilitates both data and address transfers, streamlining communications within the system.
