TAILIEUCHUNG - Lecture Business data communications: Chapter 9 - Behrouz A. Forouzan

Chapter 9 - Local area networks part I: Basic concepts and Wired Ethernet LANs. In this chapter, we discuss how the first two layers of the OSI model (physical and data link) are used to implement local area networks (LANs). In this chapter, we discuss the basics of LANs and Ethernet, the dominant LAN technology. | Chapter 9 Local Area Networks Part I: Basic Concepts and Wired Ethernet LANs Understand the use of LANs in an organization. List the components of a LAN. Be familiar with the IEEE standards. Be familiar with traditional Ethernet technology and its implementations. After reading this chapter, the reader should be able to: OBJECTIVES Be familiar with Gigabit Ethernet technology and its implementations. Be familiar with Fast Ethernet technology and its implementations. BASIC CONCEPTS Figure 9-1 A client-server model with dedicated servers Figure 9-2 A client-server model with a general server Figure 9-3 Peer-to-peer model Figure 9-4 Physical bus topology Figure 9-5 Physical star topology The star topology is the dominant physical topology today. Note: Figure 9-6 Logical bus topology In 1985, the Computer Society of the IEEE developed Project 802. It covers the first two layers of the Internet model. Note: Figure 9-7 Logical star topology Technical Focus: Ring Topology Another .
