Physical and Data-link layers.
Physical being layer 1 and Data-link being layer 2.

A NIC operates at those two layers.
The NIC operates on Layer 2 (Data Link Layer) of the OSI Model.

The OSI Model stands for Open Systems Interconnection. The answer to the question which layer of the OSI model are layers capable of functioning is at all layers.
There are seven layers in OSI model.

Ethernet is a data link layer protocol - layer 2
The OSI (Open Systems Interconnect) 7-layer model is based, in-part, on standards published by the IEEE (Institute of Electrical and Electronics Engineers). For example, IEEE standard 802.3 describes Ethernet. In the OSI model, the 802.3 standard exists at layers 1 and 2. ANSWER IEEE is a standards organization to which many hardware and software suppliers both contribute to and agree to use 'standardized' techniques. Ethernet is but only ONE of the many standards, and the OSI is only one of the usage standards.
The OSI model acts as a standard in design of computer networks. It consists of total seven layers.
