Lesson 3: Networking Media

Chapter 3


Lesson Objectives:

After reading the chapter and completing the exercises, the students should be able to:
• Define and understand the technical terms related to cabling, including attenuation, crosstalk, shielding, and plenum
• Identify three major types of both network cabling and wireless network technologies
• Understand baseband and broadband transmission technologies and when each may be used
• Decide what kinds of cabling and connections are appropriate for particular networking environments
• Describe wireless transmission techniques used in LANs
• Describe signaling technologies used for mobile computing
