What is OSI Model and How many Layers ?

Question

Accepted Answer

The OSI Model is a conceptual framework that standardizes the functions of a communication system 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 different network protocols and technologies interact.
It divides the network communication process into seven layers, each with its own specific functions.
The layers are: Physical, Data Link, Network, Transport, Session, Presentation, and Application.
Each layer provides services to the layer above it and receives services from the layer below it.
For example, the Physical layer deals with the physical transmission of data, while the Application layer handles user interfaces and network applications.
The model allows for interoperability between different vendors and technologies.
It helps in troubleshooting network issues by isolating problems to specific layers.
The OSI Model is often compared to the TCP/IP model, which is a more concise model used in modern networking.
