Here are the key differences between the OSI and TCP/IP models:

The OSI model is a conceptual framework for describing and standardizing the communication process. It consists of 7 layers - Physical, Data Link, Network, Transport, Session, Presentation, and Application. The OSI model defines the functional responsibilities of each layer, but does not specify the protocols to be used. It can be thought of as an idealized model for how networks should work.

The TCP/IP model is the network model used in the Internet and most local area networks. It consists of 4 layers - Link, Internet, Transport, and Application. The TCP/IP model specifies the core protocols used at each layer, such as IP, TCP, and UDP. It is designed to be practical and flexible, but can sometimes seem complicated or less structured compared to the OSI model.

In general, the OSI model is best suited for large enterprise networks where maintaining a structured model is important. The TCP/IP model works well for both small and large networks, and is ideal for the Internet since it specifies the core Internet protocols. The OSI model can seem more straightforward to understand, while the TCP/IP model may require deeper knowledge of the protocols. Ultimately, both models are useful for understanding how networks and the Internet function at a high level.
