How do NAT (Network Address Translation) devices fit into the OSI model, and what is their significance in modern networking?
In the realm of networking Network Address Translation (NAT) devices play a role in addressing the scarcity of IPv4 addresses and bolstering network security.
To understand the significance of NAT devices within the framework of the OSI (Open Systems Interconnection) model it is crucial to grasp an overview of this model itself.
The OSI model forms seven layers, each assigned functions for network communication.
These layers, arranged from bottom to top are Physical, Data Link, Network, Transport, Session, Presentation and Application.
Within this framework NAT devices primarily run at the Network layer (Layer 3).
Now let us explore further into how NAT devices contribute their role and significance within this context.
