Final answer:
IP datagrams correspond to the Network Layer of the ISO OSI model, which is responsible for routing, packet switching, and controlling data flow within the network.
Step-by-step explanation:
If IP runs on the Internet Layer, the datagrams that IP manages would represent the Network Layer of the ISO OSI model.
The OSI (Open Systems Interconnection) model is a conceptual framework used to understand and standardize the functions of a telecommunication or computing system without regard to its underlying internal structure and technology.
The OSI model is made up of seven layers, and the Network Layer is the third layer, which is responsible for packet forwarding including routing through intermediate routers.
The OSI model is not the same as the TCP/IP model that is used in the real world for the internet, but they are often compared due to functional similarities.
In the TCP/IP model, the 'Internet Layer' is roughly analogous to the OSI's Network Layer.
When discussing IP datagrams in the context of OSI, they operate at the Network Layer, handling routing, packet switching, and controlling the flow of data within the network.
