The network interfaces, such as enp4s0f2 and wlp3s0, serve as communication channels for data transmission between the device and the network. They physically connect the device to the network infrastructure, facilitating the exchange of information. For instance, interfaces like enp4s0f2 are associated with wired connections, while wlp3s0 is associated with wireless connections. Each interface facilitates the exchange of information, ensuring that data is appropriately routed between the device and the network.
