Throughout this book, you learned about several different cabling and con-
nector options that may be used on networks. Some, such as RJ-45, are very
common, whereas others, such as Fiber LC connectors, are used only on
newer high-speed networks. So that you can compare such connectors and
ensure that you understand their differences, this Appendix compiles draw-
ings of the connectors and a brief summary of their application in a simple
table.You must be familiar with the most popular types of connectors to
qualify for Network+ certification.You can find more detail about these con-
nectors and the networks on which they are used in Chapters 3 and 5.
