014.01.30.2. What role does the Linux kernel play in maintaining the division between the physical and internet layers, and how does it facilitate communication through the network interface?
The physical and internet layers must be connected such that the internet layer can retain its network independent flexibility. The linux kernel maintain its own division between the 2 layers and provides a communication standard for linking them called a (kernel) network interface.
The Linux kernel plays an important role in maintaining the separation between the physical and internet layers. It accomplishes this by managing network interfaces, which serve as the bridge between these layers. These interfaces enable the Linux kernel to interact with the physical layer, allowing for the transmission and reception of data across the network.
