This post will look at the Von Neumann Architecture that many computers are often based off.

What is it?

The Von Neumann architecture, also known as the Von Neumann model and Princeton architecture, is a computer architecture based on that described in 1945 by the mathematician and physicist John von Neumann and others in the First Draft of a Report on the EDVAC.

This architecture is made up of an Arithmetic Logic Unit, memory, Input/Output, control unit, and a processing unit. This design is still used in all computers and many electronic devices produced today.

The design of a Von Neumann architecture machine is simpler than that of a Harvard architecture machine, which is also a stored-program system but has one dedicated set of address and data buses for reading data from and writing data to memory, and another set of address and data buses for fetching instructions.
