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

The history of computer development is often referred to in reference to the different generations of computing devices. A generation refers to the state of improvement in the product development process. This term is also used in the different advancements of new computer technology. With each new generation‚ the circuitry has gotten smaller and more advanced than the previous generation before it. As a result of the miniaturization‚ speed‚ power‚ and computer memory has proportionally increased

Introduction For my term paper the field I chose was computers. I chose this field because I love computers and it s a field on the rise. When doing my research about computers‚ I tried to stay focused on a few different types of fields. I did this because I thought that doing every different type of field would not help me chose the right field for me. Computers is such a big field that it was almost no problem picking a couple of computer fields to talk about in my term paper. Preparation
