Introduction

The Network+ certification was developed by the Computer Technology Industry Association (CompTIA) to provide an industry-wide means of certifying the competency of computer service technicians in the basics of computer networking. The Network+ certification is granted to those who have attained a level of knowledge and networking skills that show a basic competency with the networking needs of both personal and corporate computing environments.

While most books targeted toward certification candidates present material for you to memorize before the exam, this book is different. It guides you through procedures and tasks that solidify related concepts, allowing you to devote your memorization efforts to more abstract theories because you’ve mastered the more practical topics through doing. Even if you do not aspire to become Network+ certified, this book might still be a valuable primer for your networking career.
