The network interface card (NIC) of a Local Area Network (LAN) primarily operates at the Data Link Layer (Layer 2) of the OSI model. This layer is responsible for node-to-node data transfer and framing, enabling the NIC to manage how data packets are placed on and received from the physical medium. Additionally, the NIC also interacts with the Physical Layer (Layer 1), which deals with the physical connection and transmission of raw bits over the network medium.
application layer
Router is a Layer 3 (Network Layer)device that checks packet's IP Address at input interface & routes them to interface connected to destination network if available.

The Network Interface layer
Router works in Network Layer of OSI model
The INTERNET LAYER of OSI model exists for "routing" and providing a single network interface to the upper layers.
The Seven layers of the OSI model are: Application Presentation Session Transport Network Data-Link Physical I think the answer to your question is the Application layer.
Network interface
The network access layer equivalent to the physical and data link layers of the osi model. basically this layer defines how data is physically sent through the network. There are several OSI and TCP/IP model video tutorials online.
