Data Link Control (DLC)

Data Link Control (DLC) is a set of rules that manages how data is transmitted between two devices over a network. It ensures that data is sent accurately and in the correct order by detecting errors, controlling flow, and establishing reliable communication. Think of it as the traffic controller for data, preventing collisions and making sure each message reaches its destination intact. DLC operates at the data link layer of the OSI model, providing a foundation for stable and error-free data exchange between connected computers or devices.
