Module 12: Troubleshooting

CMPS 161: Networking and Security


This module focuses on internet technologies that have not previously discussed, but are also important. This includes technologies that you are all familiar with, such as Digital Subscriber Lines (DSL) and cable modems, but also DHCP and DNS, where the latter makes it possible to type a domain name into the address bar of your browser, instead of an IP address. The second part of this module looks at the practical skill of troubleshooting. Unfortunately, technology has a tendency to not work properly or break and the culprit has to be identified and either fixed or replaced.
