History of Computer Introduction Man’s progress is measured by sophistication of his tools. First‚ he discovered how to control fire. Eventually‚ he invented the wheel. He built boats and earned to harness the wind. As soon as commerce developed in the early societies‚ people recognized the need to calculate and keep track of information. They soon devised simple computing devices and bookkeeping systems to enable them to add‚ subtract‚ and simple record transactions. Today‚ we are witnessing

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
