Keywords:

The Internet Book, Fifth Edition explains how computers communicate, what the Internet is, how the Internet works, and what services the Internet offers. It is designed for readers who do not have a strong technical background — early chapters clearly explain the terminology and concepts needed to understand all the services. It helps the reader to understand the technology behind the Internet, appreciate how the Internet can be used, and discover why people find it so exciting. In addition, it explains the origins of the Internet and shows the reader how rapidly it has grown. It also provides information on how to avoid scams and exaggerated marketing claims.

The first section of the book introduces communication system concepts and terminology. The second section reviews the history of the Internet and its incredible growth. It documents the rate at which the digital revolution occurred, and provides background that will help readers appreciate the significance of the underlying design. The third section describes basic Internet technology and capabilities. It examines how Internet hardware is organized and how software provides communication. This section provides the foundation for later chapters, and will help readers ask good questions and make better decisions when salespeople offer Internet products and services. The final section describes application services currently available on the Internet. For each service, the book explains both what the service offers and how the service works.

About the Author

Dr. Douglas Comer is a Distinguished Professor at Purdue University in the departments of Computer Science and Electrical and Computer Engineering. He has created and enjoys teaching undergraduate and graduate courses on computer networks and Internets, operating systems, computer architecture, and computer software. One of the researchers who contributed to the Internet as it was being formed in the late 1970s and 1980s, he has served as a member of the Internet Architecture Board, the group responsible for guiding the Internet’s development. Prof. Comer is an internationally recognized expert on computer networking, the TCP/IP protocols, and the Internet, who presents lectures to a wide range of audiences. In addition to research articles, he has written a series of textbooks that describe the technical details of the Internet. Prof. Comer’s books have been translated into many languages, and are used in industry as well as computer science, engineering, and business departments around the world. Prof. Comer joined the Internet project in the late 1970s, and has had a high-speed Internet connection to his home since 1981. He wrote this book as a response to everyone who has asked him for an explanation of the Internet that is both technically correct and easily understood by anyone. An Internet enthusiast, Comer displays INTRNET on the license plate of his car.

Recenzijas

"This is an excellent text for a thorough but non-technical introduction to the Internet, its usage and how it works. Comer takes a complex topic and through everyday examples and analogy makes the information clear and accessible for readers who may have no background in technology."

- Adam R. Albina, PhD, Assistant Professor, Saint Anselm College

Douglas Comer is a Distinguished Professor at Purdue University in

the departments of Computer Science and Electrical and Computer Engineering.

He has created and enjoys teaching undergraduate and graduate

courses on computer networks and Internets, operating systems, computer

architecture, and computer software. One of the researchers who

contributed to the Internet as it was being formed in the late 1970s and

1980s, he has served as a member of the Internet Architecture Board, the

group responsible for guiding the Internets development. Comer is an

internationally recognized expert on computer networking, the TCP/IP

protocols, and the Internet, who presents lectures to a wide range of audiences.

In addition to research articles, he has written a series of textbooks

that describe the technical details of the Internet. Comers books

have been translated into many languages, and are used in industry as

well as computer science, engineering, and business departments around

the world. He is a Fellow of The Association for Computing Machinery

(the major professional society in computer science) and editor of the

scientific journal, Software Practice and Experience.

Professor Comer had dial-up Internet access from his home in the

late 1970s, has enjoyed a direct connection with twenty-four hour per

day service since 1981, and uses the Internet daily. He wrote this book

as a response to everyone who has asked him for an explanation of the

Internet that is both technically correct and easily understood by anyone.

An Internet enthusiast, Comer displays INTRNET on the license plate of

his car.
