What is the difference between Von Neumann and Harvard Architecture?

As an architect in today’s world, you would create your drawings with computer software compared to decades ago when architects used paper and pencil to make their drawings. A mathematician named John Von Neumann created an architecture and named it after himself. Another type of architecture for the computer is called the Harvard Architecture.

Von Neumann architecture is known to be more general and less specific or sophisticated. There are three parts of the Von Neumann architecture, and they are the central processing unit, input/output interfaces the memory unit. Von Neumann architecture is cheaper than Harvard architecture. Von Neumann architecture can be used on almost any type of electronic device, but the Harvard architecture can’t be used on any device.
