Now that you have reached the end of this chapter, you should feel comfortable configuring network connections and services in macOS and using the tools available for that purpose. You have revisited essential networking concepts, such as the OSI model and the TCP/IP model, and how they work to make networking possible. You have also reviewed other important concepts, such as network interfaces and network protocols, as well as which ones are supported by macOS. By now, you can connect to Wi-Fi and other networks, create network locations for specific places and/or restrictions, and configure other network services, such as a VPN network. At the same time, you are able to make advanced changes to the network configuration.
In the next chapter, we will go into network services in greater detail, including how to use the sharing services available in macOS to make your work faster and easier.
