This book is a concise summary of networking concepts and draws upon the work of several Pearson authors. Thank you to Keith Barker, Emmett Dulaney, Anthony Sequeira, and Kevin Wallace for blazing a trail in the Network+ domain by authoring some outstanding resources for the reader.
Thank you to my technical editor, Chris Crayton, who is a tough task master and excellent subject matter expert. This book was made much better by his attentive guidance.
The Digital Study Guide version of this book includes activities, videos, and quizzes for each day.
I am grateful to Dan Alberghetti for agreeing to do the videos. Students of Cisco Network Academy will be familiar with his work. But you can also find Dan’s work at his website,
