Networking is one of the most critical domains in Core 1, and this overview episode sets the stage by introducing the topics covered under Domain 2.0. You’ll get an outline of what CompTIA expects you to know about network cables, ports, protocols, hardware devices, configuration, and wireless technologies. We explain how this domain fits into the bigger picture of troubleshooting and supporting modern IT environments, especially for help desk and support technician roles.

We also provide tips on how to structure your networking study sessions and what areas students often find most challenging—such as port numbers, IP addressing, and wireless standards. With this overview, you’ll know what to expect as you move into more detailed episodes on protocols, tools, and infrastructure. This episode gives you the confidence to tackle the networking section with a focused mindset. Brought to you by BareMetalCyber.com.
