Knowing how to install, configure, and troubleshoot a computer network is a highly market able and exciting skill. This book first introduces the fundamental building blocks that form a modern network, such as protocols, media, topologies, and hardware.

After reading this book and completing the end-of-chapter exercises, you will be prepared to select the best network design, hardware, and software for your environment. You will also have the skills to build a network from scratch and maintain, upgrade, troubleshoot, and manage an existing network. Finally, you will be well-prepared to pass CompTIA’s Networkþ N10-006 certification exam. This book explains technical concepts logically and in a clear, approachable style. In addition, concepts are reinforced by real-world examples of networking issues from a professional’s standpoint. Each chapter opens with an “On the Job” story from a network engineer, technician, or administrator. These real-world examples, along with Applying Concepts activities, Hands-On Projects, and Case Projects in each chapter, make this book a practical learning tool. The numerous tables and illustrations, along with the glossaries, appendices, and study questions, make the book a valuable reference for any networking professional.
