IT Essentials Companion Guide v6

The Companion Guide supplements and complements the IT Essentials v6 online curriculum offered by the Cisco Networking Academy.

The Companion Guide is designed as a supplemental textbook for the Networking Academy course. The purpose for this textbook is to offer students a portable desk reference of the course content to use anytime anywhere as a study aid. The chapter content will align 1:1 to the online course module topics, but not necessarily word-for-word. The contributing author has extensive classroom experience and will present the course material in the Companion Guide in a comprehensive manner, providing his own examples where necessary to augment a student¡¦s understanding of the course material.

The features of the Companion Guide are designed to help you study and succeed in this course:

• Chapter Objectives - Review core concepts by answering the focus questions listed at the beginning of each chapter.
• Key Terms - Refer to the updated lists of networking vocabulary introduced and turn to the highlighted terms in context in each chapter. The terms are defined in the glossary.
• Check Your Understanding Questions and Answer Key - Evaluate your readiness with the updated end-of-chapter questions that match the style of questions you see on the online course quizzes.

Virtual Desktop, Virtual Laptop, and Packet Tracer Activities, on the CD that accompanies this book, are virtual learning tools to help you develop critical thinking and complex problem-solving skills. New for this edition, Cisco Packet Tracer simulation-based learning activities promote the exploration of networking and network security concepts and allow you to experiment with network behavior.

The Companion Guide serves as an additional instructional tool for the instructor to assign take-home reading or give vocabulary quizzes to better prepare the students for in-class lab work and presentations.
