Description: The network layer model is a conceptual framework used to understand and implement network protocols. This model divides communication functions into different layers, each of which has a specific purpose and communicates with adjacent layers. Typical layers include the physical layer, data link layer, network layer, transport layer, session layer, presentation layer, and application layer. This modular approach allows network developers and administrators to design, implement, and troubleshoot networks more efficiently, as each layer can be developed and modified independently. Furthermore, the network layer model facilitates interoperability between different systems and technologies, as it defines standards and protocols that can be used across various manufacturers and platforms. In summary, the network layer model is fundamental to the understanding and development of modern networks, providing a clear and structured framework for data communication.
