Guide to Networking Essentials, Ninth Edition

Building a clear picture of how networks work means connecting the fundamentals to the equipment and decisions that keep them running. Guide to Networking Essentials, Ninth Edition by Greg Tomsho takes readers from basic networking concepts through the technologies, administration, and troubleshooting involved in computer networks.

Start with the building blocks

The opening chapters introduce computer networks, communication, network hardware, topologies, media, and protocols. From there, the book develops core skills and concepts such as IPv4 and IPv6 addressing, subnetting, network reference models, Ethernet, Wi-Fi, and the roles of switches, routers, and wireless access points.

Explore the systems behind a working network

Later chapters turn to network security, wide-area networking, cloud computing, network operating systems, and day-to-day management. Coverage also extends to the Internet of Things and troubleshooting, giving readers a view of networking that reaches beyond cables and devices to include the services and support networks depend on.

Connect concepts with review and practice

Chapter summaries, key terms, review questions, and case projects give readers ways to revisit the material and work with its ideas. The book also includes a network troubleshooting guide and a mapping to the Cisco CCST 100-150 exam objectives.

A useful foundation for networking study

Students and readers beginning to study network infrastructure, support, or administration can use this ninth edition to build a structured grounding in networking essentials. Its progression from introductory concepts to security, operations, and troubleshooting helps put the many parts of a network into context.
