Chapter 2. Cabling and Connectors
OBJECTIVES
This chapter covers the following CompTIA-specified objectives for the “Media and Topologies” section of the Network+ certification exam:
Recognize the following media connectors and describe their uses:
RJ-11
RJ-45
AUI
BNC
ST
SC
Specific cable types use one or more types of connectors. Being able to identify which connector is associated with which cable is an important skill for a network administrator.
Specify the characteristics (e.g., speed, length, topology, cable type, etc.) of the following 802.3 (Ethernet) standards:
10BaseT
10BaseTX
A wide variety of network media are used in networking. To pass the Network+ exam, you will need to understand the various media types and their characteristics.
Choose the appropriate media type and connectors to add a client to an existing network.
As a network administrator, you will work in a range of environments. Understanding the requirements to connect systems to the network is a key skill.
