Network configuration in Linux

To access the internet, you need the following components:

• The driver of the network device installed and enabled. (See Linux drivers for more details.)
• A network manager to manage your network devices ;p
• A DNS resolver to access domain names which are aliases to IP addresses.

There are competing components to manage your network configurations.

• There is NetworkManager that has been the standard way for managing networks. It is being used in roam:GNOME as the backend for their network management interface.
• If you're using systemd-ful environment, you can start with systemd-networkd.
