ccna 200 301 booksmart trailer girl.subnetting, and routing, you need to have a general understanding of the LANand be able to answer these two questions: How is Ethernet used in today's networks?How are Ethernet networks used today? What are MAC (medium access control) addresses and how are they used?This chapter will answer these two questions and much more. Not only will it discuss the fundamentals of Ethernet and the use of MAC addresses in Ethernet LANs, but it will also introduce the protocols used at the Ethernet data link layer. The various Ethernet definitions will also be introduced.As you learned from Chapter 2, each layer of the OSI model defines many different devices, and one thing that must be known is that connecting all of these devices to the network requires the use of many types of cables and connectors. This chapter will cover the various cable technologies used by Cisco devices, and will cover not only how to connect a router or switch, but also how to use a management terminal (Console) to connect a router or switch.This chapter will also introduce the concept of encapsulation, which is the process of encoding data as it enters the OSI protocol stack.To conclude this chapter, you will be presented with 20 test questions and four written labs. These tests will help you really understand what you've learned in this chapter, so don't skip them!Get the latest content from this chapter at: www.lammle.com/forumo3.1 Reviewing Ethernet NetworksEthernet (Ether) is a contention-based medium access method that allows all hosts in a network to share the same link bandwidth. Ethernet is widely deployed because it is easily scalable, meaning that it can integrate new technologies, such as upgrading Fast Ethernet to Gigabit Ethernet, into existing network architectures with relative ease. And it is also relatively simple to deploy at first, and because of this, the idea when troubleshooting is clear. Ethernet uses both data link layer and physical layer definitions, and this chapter will provide you with all the data link layer and physical layer information you need to effectively deploy, troubleshoot, and maintain Ethernet.
