Osi vs tcpip model structure functionality

Question

What distinguishes the OSI model from the TCP/IP model in terms of structure and functionality?

Answer

The OSI model has seven layers (Application, Presentation, Session, Transport, Network, Data Link, Physical), while the TCP/IP model has four layers (Application, Transport, Internet, Link). The OSI model is more theoretical and used for understanding networking concepts, whereas the TCP/IP model is more practical and widely implemented in real-world networking.
