List two ways in which the OSI Reference Model and TCPIP Model are the same. Now list two ways in which they differ.?

Both the OSI Reference Model and the TCP/IP Model are layered architectures that facilitate network communication by organizing functions into distinct layers, enabling interoperability between diverse systems. They both aim to standardize networking protocols to ensure effective data transmission across networks.

However, they differ in structure: the OSI Model has seven layers (Application, Presentation, Session, Transport, Network, Data Link, and Physical), while the TCP/IP Model has four layers (Application, Transport, internet, and Network Access). Additionally, the TCP/IP Model was developed based on practical implementation and widely used protocols, whereas the OSI Model was created as a theoretical framework.
