protocol layer

A protocol layer is like a specific rulebook within a larger system that ensures different devices can communicate smoothly. Think of it as a group of associated protocols, each handling a particular function—such as sending data, checking for errors, or managing connections. These layers work together, with each layer performing its role and passing information to the next, to make sure messages get delivered accurately and efficiently. This layered approach helps in organizing complex communication processes, making networks reliable, scalable, and easier to troubleshoot.
