Explain OSI model and its layers

Question

Accepted Answer

The OSI model is a conceptual framework that defines the functions of a network into seven layers.

The OSI model stands for Open Systems Interconnection model.
It was developed by the International Organization for Standardization (ISO) in 1984.
The model helps in understanding how network protocols and technologies interact with each other.
The seven layers of the OSI model are: Physical, Data Link, Network, Transport, Session, Presentation, and Application.
Each layer has its own specific functions and protocols.
The layers work together to ensure reliable and efficient communication between devices on a network.
For example, the Physical layer deals with the physical transmission of data, while the Application layer handles user interfaces and network services.
The OSI model provides a standardized framework for network communication, allowing different vendors and technologies to work together seamlessly.
