CHAPTER 10

Network Devices

Various hardware devices can be deployed to connect a network. Knowledge of how they work and where to place them is critical to designing the network. A poorly designed network will be difficult to optimize, regardless of the quality of the equipment.

This chapter is dedicated to the understanding of the role played by each device and the principles that drive the positioning of each. Specifically, this chapter covers the following topics:

• Describing device functions
• Understanding device placement principles
