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 helps in understanding how different network protocols interact and communicate 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.
For example, the Network layer is responsible for routing and addressing, while the Transport layer ensures reliable data delivery.
The OSI model provides a hierarchical structure for network communication.
It allows for interoperability between different network devices and technologies.
Understanding the OSI model is essential for troubleshooting and designing network systems.
