The OSI (Open Systems Interconnection) model is a conceptual framework that characterizes and standardizes the communication functions of a telecommunication or computing system without regard to its underlying internal structure and technology. It divides the communication system into seven layers: Application, Presentation, Session, Transport, Network, Data Link, and Physical. Each layer performs specific functions to enable interoperability between diverse network systems. It's commonly used as a reference model for understanding and designing network protocols and architectures.
