05/20: TCP/IP vs OSI Model: The Ultimate Comparison
The article compares the TCP/IP and OSI models, highlighting their distinct purposes in networking. While the OSI model serves as a conceptual framework for understanding networking, the TCP/IP model is built around practical, working protocols. Both models aim to facilitate reliable communication across networks, but they differ in structure and application.
- ▪The OSI Model has seven layers, while the TCP/IP Model has four layers.
- ▪The OSI Model was developed as a universal reference framework, whereas the TCP/IP Model emerged from practical networking research.
- ▪TCP/IP became the dominant networking architecture because it addressed real-world problems before the OSI Model was widely adopted.

Instead, modern networks operate using the TCP/IP Model, a separate networking framework with only four layers. This often creates confusion.
