IT-320 Chapter 1 Introduction to Networks Slide 2 Objectives 1.
Differentiate between LANs, MANs, and WANs. 2. List and describe
the components that make up a network. 3. Given a network problem
scenario, select an appropriate course of action based on a general
troubleshooting strategy. 4. Describe the importance and use of
documentation. 5. Identify the purpose, features, and functions of
Hubs, Switches, Bridges, Routers, Gateways, and NICs. 6. Describe
the OSI Model and how it relates to networks. 7. Recognize the
different logical or physical network topologies given a diagram.
8. Specify the main features of the 802.2 LLC and MAC Layers. 9.
Given an example, identify a MAC address. 10. Identify the seven
layers of the OSI model. 11. Identify which layers of the OSI model
different network devices operate. 12. Explain the need for network
standardization. 13. Define a Virtual Circuit. 14. Define sessions,
explaining how they relate to networks. 15. List and define the 802
Project Standards. 16. Define signaling, modulation, and encoding.
17. Define bandwidth and compare broadband with baseband. 18. List
and describe the different connection services. Slide 3 FIGURE 1-1
