What is the “OSI model” in networking?

Answer:

Explanation:

The OSI (Open Systems Interconnection) model is a conceptual framework used to understand and standardize the functions of a networking system. It divides network communication into seven distinct layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application.

Each layer has a specific function, and the OSI model helps network professionals troubleshoot issues by isolating problems to a particular layer. For example, the Physical layer deals with the actual hardware connections, while the Application layer deals with user interfaces and software applications.

The OSI model provides a universal language for understanding how data is transmitted across a network and how different devices and protocols interact with each other.
