TCP/IP vs. OSI Model: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Updated on October 9, 2023
TCP/IP is a suite of communication protocols used on the internet, while OSI model is a theoretical framework that describes networking layers.

Key Differences

TCP/IP, standing for Transmission Control Protocol/Internet Protocol, is a set of protocols vital for internet communication. On the other hand, the OSI model, or Open Systems Interconnection model, is a conceptual framework used to understand network interactions in seven distinct layers.

TCP/IP originated from the ARPANET, the precursor to the internet, and became the foundation for the modern web. In contrast, the OSI model was developed by the International Organization for Standardization (ISO) to provide a clear, layered model for network architecture.

TCP/IP operates on a four-layered model: Application, Transport, Internet, and Network Access. The OSI model, however, divides the networking process into seven layers: Application, Presentation, Session, Transport, Network, Data Link, and Physical.

While TCP/IP is widely used for real-world applications and forms the backbone of the internet, the OSI model remains largely theoretical, primarily utilized for teaching and reference.
