Chapter 1. Introduction to Computer Organization and Computer Evolution I. Computer Organization and Computer Architecture In describing computers‚ a distinction is often made between computer architecture and computer organization. Although it is difficult to give precise definitions for these terms‚ a consensus exists about the general areas covered by each. Computer Architecture refers to those attributes of a system visible to a programmer or‚ put another way‚ those attributes that have a

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

Computer Hardware came about when machines needed separate manual actions to be able to perform specific mathematical functions. Luckily in 1941‚ a man by the name of Konrad Zuse invented what was considered the first working‚ fully operable computer. Prior to this‚ most of the calculations were done manually to calculate by people with adding machines. Today these adding machines are better known as calculators. Back then‚ all you had to do is push buttons‚ but in today’s modern software technology
