who proposed the architecture of the computer system

The architecture of the modern computer system is largely attributed to mathematician John von Neumann.

In 1945, von Neumann and his colleagues proposed the von Neumann architecture, which outlined a foundational design for computers. This architecture consists of key components like:

• A central processing unit (CPU) with an arithmetic logic unit (ALU) for calculations and a control unit to manage instructions.
• Memory to store both data and programs.
• Input/output (I/O) devices for interacting with the outside world.
• Secondary storage for permanent data storage.
