Book Preface

Guide to Networking Essentials, Eighth Edition, serves the needs of students, instructors, aspiring information technology profes-sionals, and others who are interested in learning more about networking technologies but might have little or no background in this subject matter. This book’s extensive and broad coverage of computer networking technologies and network operating systems gives you a solid networking background to pursue a number of certifications, including MTA Networking Fundamen-tals, Network+, CCENT, CCNA, MCSA, and Security+. The eighth edition maps to the MTA 98-366 Networking Fundamentals cer-tification, and many instructors also use the book for Network+ and CCENT test preparation. With the extensive use of tables that compare important properties of networking technologies, this book also makes an excellent reference.

The eighth edition builds on the strengths of the seventh edition, giving you easy-to-understand explanations of often difficult concepts and a solid grounding in topics such as rout-ing, switching, IP addressing, and virtualization. Many students are learning computer concepts at the same time they’re learn-ing about networking, so the first chapter includes a refresher on computer components and terminology. This new edition covers the latest networking technologies and operating systems, including new Ethernet and Wi-Fi standards, cloud computing, Windows 10, Windows Server 2019, and recent Linux distributions. In keeping with the latest trends in network-ing, this edition includes an all-new chapter on the Internet of Things (IoT), including use cases, network technologies, com-mon IoT devices, and hands-on projects.
All-new Packet Tracer labs in this book use network simula-tion software, so many of the labs that use physical equipment such as switches and routers can be completed in a virtual environment. Challenge labs give you an opportunity to apply what you have learned from the chapter material and hands-on projects in a format that might require additional research and skills. For case projects, you use your knowledge and critical thinking skills to devise solutions to networking problems.
The simulations in previous editions of Guide to Network-ing Essentials are deprecated and are no longer offered as a download from Cengage. However, the author has made them available on his Web site for readers who still want to use them. These simulations with audio narrations give you an innovative tool to help you grasp difficult networking concepts. They cover topics ranging from basic LAN communication to Network Address Translation (NAT) and Internet e-mail operation. Drag-and-drop exercises reinforce concepts of the OSI model and network frame formats. These simulations are written in Flash, so Flash must be enabled in your browser. You can access the simulations on the author’s Web site at http://books.tomsho.com/sims.

Intended Audience
Guide to Networking Essentials, Eighth Edition, is intended for people who are getting started in computer networking and want to gain a solid understanding of a broad range of networking technologies. This book is ideal for would-be information technol-ogy professionals who want to pursue certifications in a variety of computer net-working fields as well as professionals in a managerial role who want a firm grasp of networking technology concepts. To understand the material in this book, you should have a background in basic computer concepts and experience using the Windows operating system. This book is ideal for use in a classroom or an instructor-led training environment and is also an effective learning tool for individual self-paced training.

Coping with Change on the Web
Sooner or later, all the specifics on Web-based resources mentioned in this book will become outdated or be replaced by newer information. In some cases, entering a URL shown in this book might lead to an updated URL; in other cases, it will lead nowhere, resulting in the dreaded error message “Server not found.”

When that happens, please don’t give up! There’s always a way to find what you want on the Web, if you’re willing to invest some time and energy. Most large or com-plex Web sites offer a search engine. As long as you can get to the site itself, you can probably use its search engine to help you find what you need. In addition, try using general search tools, such as www.google.com or www.bing.com, to find related infor-mation. The bottom line is if you can’t find something where the book says it should be, start looking around. It’s likely to be somewhere!

• Screen captures, illustrations, and tables—Numerous screen captures and illustrations of concepts help you visualize network setups, theories, and architectures and see how to use tools. In addition, tables summarize details in an at-a-glance format and give you comparisons of both practical and theoretical information; they can be used for a quick review. Because most school labs use Windows OSs, these products have been used for most screenshots and hands-on projects.
• Packet Tracer labs—Using Packet Tracer, readers can perform labs using virtual network hardware. These labs are written to mirror the hands-on projects whenever possible so labs can still be done even when the physical hardware is not available.
• Chapter summary—Each chapter ends with a summary of the concepts introduced in the chapter. These summaries are a helpful way to recap the material covered in the chapter.
• Key terms—All terms introduced with bold text are gathered together in a Key Terms list at the end of each chapter. This list gives you an easy way to check your understanding of important terms and is a useful reference.
• Review questions—The end-of-chapter assessment begins with review questions that reinforce the concepts and techniques covered in each chapter. Answering these questions helps ensure that you have mastered important topics.
• Critical Thinking sections—The end-of-chapter Critical Thinking section gives you more opportunities for hands-on practice with challenge labs, which enable you to use the knowledge you’ve gained from reading the chapter and performing  hands-on projects to solve more complex problems without step-by-step instructions. This section also includes case projects that ask you to evaluate a scenario and decide on a course of action to propose a solution. These valuable tools help you sharpen decision-making, critical thinking, and troubleshooting skills—all important aspects of network administration.
