Assignment 1: Computer Archtecture Intro to Info Technology – CIS 106031VA016-1144-001 Professor John Murnane May 4‚ 2014 Von Neumann Architecture Von Neumann architecture is a stored program architecture with no differentiation between data and instruction memory. Both the data and instruction reside on a single chip. The concept of no differentiation between data and instruction memory is accurate‚ but existing on one chip has nothing to do with it. Most computer memories
