CHAPTER 7WIRED AND WIRELESS LOCAL AREA NETWORKS

This chapter examines the three major network architecture components that use local area networks (LANs): the LANs that provide network access to users, the data center, and the e-commerce edge. We focus on the LANs that provide network access to users as these are more common. This chapter draws together the concepts from the first section of the book on fundamental concepts to describe how wired and wireless LANs work. We first summarize the major components of LANs and then describe the two most commonly used LAN technologies: wired and wireless Ethernet. The chapter ends with a discussion of how to design LANs and how to improve LAN performance.

OBJECTIVES

• Understand the major components of LANs
• Understand the best practice recommendations for LAN design
