Show answer & explanation
Correct answer: B
The OSI (Open Systems Interconnection) model is a conceptual framework used to understand and implement network protocols in seven distinct layers. These layers are: Physical, Data Link, Network, Transport, Session, Presentation, and Application. Each layer has a specific function in data communication, and together they ensure seamless data transfer across networks.
