Layer 2 of the TCP/IP Model is known as the

Layer 2 in the TCP/IP model is the Link Layer, sometimes called the Network Interface Layer. This layer covers what happens on the local network segment—the hardware addressing and framing that let devices on the same physical network talk to each other. It’s where Ethernet or Wi‑Fi operate, and where address resolution (mapping IP addresses to MAC addresses) is used to actually send frames on the local network. The term Data Link Layer is more common in OSI terminology for the same concept, while the Internet label corresponds to Layer 3 in TCP/IP, which handles IP addressing and routing between networks. So the best fit for Layer 2 in TCP/IP is the Link Layer.
