Data Link Control

Data Link Control refers to the set of procedures and methods that ensure reliable communication between two devices over a network. It manages how data is formatted, transmitted, and checked for errors, making sure messages are delivered accurately and in the correct order. Think of it as the rules and systems that guarantee a clear and error-free "conversation" between devices, like computers or routers, over a physical connection. This process helps prevent data loss, duplication, or confusion during transmission, ensuring smooth and trustworthy communication in network systems.
