TABLE OF CONTENTS In this chapter we will cover WAN (wide area network) standards and security protocols that you will see not only on the CompTIA Network+ exam, but also in a large production environment. Most of these protocols and standards are used often and you will need to know about them for the Network+ exam. For the Network+ exam, be familiar with the speeds, capacities, and the types of media used for each WAN technology covered.
By the end of this chapter, you will know the specifics of the following WAN Protocols: ISDN (Integrated Services Digital Network), T1, E1, and X.25. You will also understand the basic characteristics of specific WAN technologies, such as how packet switching and circuit switching differ.

WANs may be created in different configurations, with the most common being some combination of public networks and private networks. When working within the realm of a public network, you are...
