You may be looking at the title of this section and wondering why are we covering such an old technology. The simple answer to this is that, despite its age, dial-up is still used. However, unless you're living in rural areas where faster methods are not available, it is unlikely that it would be used as a primary means of connection to a WAN. In most instances, dial-up would be used as a backup means of connectivity, used for allowing support staff to connect and rectify any issues with the primary means of connection. Imagine that you are an on-call network engineer, and someone calls you up in the middle of the night to report that there is no internet access. You try to connect to the router from home, but there is no connectivity. You then use a dial-up connection to dial into the network, connect to the router via its internal interface, and rectify...
