Network layering

Network layering is like organizing a complex task into simpler, manageable steps. Each layer in a network handles a specific part of data communication, such as formatting, routing, or error checking. These layers work together hierarchically, passing data from one to the next until it reaches its destination. This structure makes it easier to troubleshoot, develop, and update networks, because changes in one layer don't necessarily affect the others. Think of it as a multi-step process where each step has a clear role, ensuring that information travels reliably and effectively across different devices and networks.
