Networking Concepts Review
This chapter reviews the OSI model for data communication. General networking concepts,
such as routers, bridges, and routing concepts are discussed. Number conversion among
binary, hexadecimal, and decimal format is reviewed. It might seem that this chapter covers
a little of everything, but all concepts in this chapter provide the foundation you need to
master for the topics presented in the chapters that follow.
“Do I Know This Already?” Quiz
The purpose of this assessment quiz is to help you determine how to spend your limited

Summary section and answer the questions at the end of the chapter to ensure that you have
a strong grasp of the material covered. If you intend to read the entire chapter, you do not

comfortable with your ability to answer all the Q & A questions at the end of the chapter.
The following questions are repeated at the end of the chapter in the Q & A section with
