Explanation
The TCP/IP model has four layers: Application, Transport, Internet, and Network Interface (also called the Link layer). The Network Interface layer of TCP/IP maps to the two lowest layers of the OSI model: Physical (Layer 1), which handles raw bit transmission over a medium, and Data Link (Layer 2), which handles MAC addressing, framing, and error detection. The other OSI layers map differently: Application, Presentation, and Session (Layers 7, 6, 5) map to the TCP/IP Application layer; Transport (Layer 4) maps to TCP/IP Transport; and Network (Layer 3) maps to TCP/IP Internet.
