Von Neumann programming languages

A von Neumann language in computing is a programming language that is a high-level abstract isomorphic copy of a von Neumann architecture. As of 2009, most current programming languages fit into this description, likely as a consequence of the extensive domination of the von Neumann computer architecture during the past 50 years.

The differences between Fortran, C, and even Java, although considerable, are ultimately constrained by all three being based on the programming style of the von Neumann computer. If, for example, Java objects were all executed in parallel with asynchronous message passing and attribute-based declarative addressing, then Java would not be in the group.

The isomorphism between von Neumann programming languages and architectures is in the following manner:

program variables ↔ computer storage cells
control statements ↔ computer test-and-jump instructions
assignment statements ↔ fetching, storing instructions
expressions ↔ memory reference and arithmetic instructions.
