A router operates at the third layer of the OSI model, which is the Network Layer. Here are the steps to understand why:

1. The OSI model, or Open Systems Interconnection model, is a conceptual model that characterizes and standardizes the communication functions of a telecommunication or computing system without regard to its underlying internal structure and technology.

2. This model is divided into seven different layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application.

3. The Network Layer, which is the third layer of this model, is responsible for packet forwarding, including routing through intermediate routers.

4. Routers, therefore, operate at this layer because their primary function is to connect different networks and direct packets to their final destination by the most efficient route.

5. So, routers use the Network Layer protocols to determine the best path for forwarding the packets of data they receive.
