This Book's Approach to Data Communications

The modern society we live in today is a communications-oriented society. Thus, the goal of this book is to assist readers in understanding how this society operates by examining the basic structure of the field of data communications. This book explains how different communications devices operate, describes the different types of transmission facilities used to transport information, and examines such emerging technologies as digital subscriber lines and cable modems that might revolutionize the manner by which we work. For readers who surf the Web with conventional modems, imagine being able to transmit and receive data at a speed several orders of magnitude beyond what we now do. The possibilities for new applications become almost endless. Soon, we will be able to visit museums and join virtual lectures on the style of different artists, and we'll be able to zoom in to see minute details that might previously have required a trip around the world. Soon, we will be able to talk and view our parents, business associates, or pen pals located hundreds or thousands of miles away as if they were in our living rooms or offices, and we will do so not only on our home computer but on our cell phone! So join me in examining the field of data communications as we explore its evolution and the technical aspects of equipment and transmission facilities that make the wonderful world of data communications a reality.
