Osi layer and how to packet send

Question

Accepted Answer

The OSI layer is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven abstraction layers.

The OSI model consists of 7 layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application.
Each layer has specific functions and communicates with the corresponding layer on the receiving end.
When a packet is sent, it is encapsulated at each layer with header information before being transmitted over the network.
The packet travels down the OSI layers on the sending device, then up the layers on the receiving device.
For example, when you send an email, the application layer (Layer 7) on your computer communicates with the application layer on the email server.
The email message is then broken down into packets, each encapsulated with header information at the transport layer (Layer 4) before being sent over the network.
