Comparing TCP/IP and OSI Model

Posted 28th Dec 2022 by Sakshyam Shah

TCP/IP and OSI model serves a similar purpose - to map all the bits and pieces involved in networked communication. While OSI is the recommended standard, the internet was designed around the TCP/IP model.

The diagram below compares TCP/IP and OSI models.

In the OSI model, the Application layer of TCP/IP is further categorized into three layers: application, presentation, and session layer, and the data link layer of TCP/IP is further classified into two layers: data link and physical layer. The transport and network layer covers the same functions in both TCP/IP and OSI models.
