The network Card(NIC) is on Layer 2, but the connector on the NIC is considered Layer 1 because the connector is considered a physical connection.
Layer 1 ------Physical
Layer 2 ------Data
According to Network+ the answer is Physical.
when the data reaches the network layer. some control informations will be added along with the data..that is encapsulation. here data will be encapsulated by adding the information of ip address of the source and destination.
In this layer datas are in the form of packets.
protocols participates in this layer : tcp/ip

In the OSI reference model, that would be layer 3 (network).In the OSI reference model, that would be layer 3 (network).In the OSI reference model, that would be layer 3 (network).In the OSI reference model, that would be layer 3 (network).
network layer
A network bridge connects multiple network segments at the data link layer (Layer 2) of the OSI model.

If you mean the OSI reference model, that's layer 1 (physical).If you mean the OSI reference model, that's layer 1 (physical).If you mean the OSI reference model, that's layer 1 (physical).If you mean the OSI reference model, that's layer 1 (physical).
Networking layer of the OSI model
The network layer. # Physical # Data Link # Network # Transport # Session # Presentation # Application
Router works in Network Layer of OSI model
Layer 3 i.e, network layer of the OSI model is used to IP addressing.
Physical layer which is the first layer in OSI reference model is responsible for signal encoding and decoding.
There are seven type of OSI reference model:-Layer 7: The application layer Layer 6: The presentation layer Layer 5: The session layer Layer 4: The transport layer Layer 3: The network layerLayer 2: The data-link layer Layer 1: The physical layer
