What is OSI model?

The OSI (Open Systems Interconnection) model is a conceptual framework used to describe the functions of a networking system. It characterizes and standardizes communication functions into seven abstraction layers: Application, Presentation, Session, Transport, Network, Data Link, and Physical. It's commonly used as a teaching tool and reference for understanding network protocols and how they interact.
