what is networking and osi model

Question

Accepted Answer

Networking is the practice of connecting devices to share resources. OSI model is a conceptual framework for network communication.

Networking involves connecting devices to share resources such as data, printers, and internet access.
OSI model is a conceptual framework that defines how data is transmitted over a network.
It consists of seven layers, each with a specific function, from physical transmission to application-level communication.
The layers are: Physical, Data Link, Network, Transport, Session, Presentation, and Application.
Each layer communicates with the layer above and below it to ensure data is transmitted accurately and efficiently.
For example, when you visit a website, your computer sends a request through the layers of the OSI model to the server, which responds with the requested data.
Understanding the OSI model is important for troubleshooting network issues and designing efficient networks.
