Chapter 3. LAN Technologies


Terms you'll need to understand:

  • Active Monitor

  • autonegotiation

  • broadcast domain

  • collision domain

  • network diameter

  • network sniffer

  • network topology

  • bus topology

  • ring topology

  • star topology

Techniques you'll need to master:

  • Know and identify different LAN topologies

  • Understand different LAN devices in a network

  • Understand Ethernet technology

  • Identify a star topology, and know its speeds and capabilities

  • Understand Token Ring and the ring topology

  • Understand the capabilities of ATM and its advantages

  • Understand the advantages of segmenting

The focus of this book is to prepare for an exam that covers supporting and troubleshooting Cisco networks. In order to prepare for this exam, you need to understand some of the principles and media types used in today's networks in order to begin troubleshooting. You should have a good knowledge of different topologies and how certain media standards operate . The IEEE media standards you should know for the exam are the Ethernet, Fast Ethernet, Gigabit Ethernet, ATM, Token Ring, and wireless standards.

For the exam, Cisco expects you to know many aspects of the network. You should understand how hubs, bridges, switches, and routers segment the networks, as well as how they divide broadcast and collision domains. In this chapter, I give you an overview of the different LAN topologies and the IEEE LAN media standards you need to know in order to do well on the CCNP exam.
