What is OSI Model?
The OSI (Open Systems Interconnection) model is a conceptual framework that standardizes the functions of a network into seven distinct layers, from physical transmission up to application-level communication. It was developed to help different systems and vendors communicate using common standards, making troubleshooting and network design more systematic. Each layer has a specific role and interacts only with the layers directly above and below it.
