Wired and Wireless Networks

THE FOLLOWING NETWORK+ EXAM OBJECTIVES
ARE COVERED IN THIS CHAPTER:

1.7 Specify the general characteristics (for example, carrier
speed, frequency, transmission type, and topology) of the

following wireless technologies:

• 802.11 (frequency hopping spread spectrum), 802.11x (direct sequence spread spectrum)

• Infrared
• Bluetooth

1.8 Identify factors which affect the range and speed of

wireless service (for example, interference, antenna type,

and environmental factors).

3.3 Identify the appropriate tool for a given wiring task (for

example, wire crimper, media tester/certifier, punchdown

tool, or tone generator).

This chapter brings you to the most important test of all: your

ability to install new network hardware and software. The Network+ exam tests your knowledge of the basic network hardware components that you might install as well as how to successfully upgrade outdated hardware or software. In this chapter, we’re going to examine what you should consider before you upgrade, some common network components you might install, whether they should be wired or wireless, and how you connect them.
