How is the network layer of the OSI model identified in the TCP/IP model?Network Access LayerTransport LayerInternet LayerApplication Layer

In the TCP/IP model, the network layer of the OSI model is represented by the Internet Layer. The OSI (Open Systems Interconnection) model consists of seven layers, while the TCP/IP model compresses these into four layers.

Breakdown of Layers:

1. Application Layer in TCP/IP corresponds to the Application, Presentation, and Session Layers in OSI.
2. Transport Layer is directly equivalent in both models.
3. Internet Layer in TCP/IP corresponds to the Network Layer in OSI.
4. Network Access Layer (or Link Layer) in TCP/IP corresponds to both the Data Link and Physical Layers in OSI.

This mapping shows that while the two models use different terminologies and structures, there is a clear correspondence between the layers in terms of functionality and purpose within networking protocols.
