The OSI model gives standardization to various gadgets like switches, motherboards, routers, and other devices. At the same time, the TCP/IP model connects various computers. The header size of OSI is a minimum of five bytes. In comparison Both TCP/IP Model and OSI Reference Model have layered architecture and also their functionality almost look similar. The main difference between them is, OSI reference model provides clear distinction between services,interface and protocols, whereas, TCP/IP doesn’t able to differentiate between them. TCP/IP is the communication protocol to connect hosts to the Internet, while OSI is a reference model for communication between end users in the network. Transmission Control Protocol is used by Internet applications like email, world wide web, FTP, etc.

The following picture show the comparison between the TCP/IP model and OSI model: As you can see from the picture above, the TCP/IP model has fewer layers than the OSI model. The Application, Presentation, and Session layers of the OSI model are merged into a single layer in the TCP/IP model.

21 Nov 2011 This chapter explains the terminology and concepts behind TCP/IP. It also explains the terminology behind the OSI networking model in comparison to TCP/ IP.

2020-11-17 · TCP/IP was already on the path of development when the OSI standard architecture appeared and, strictly speaking, TCP/IP does not conform to the OSI model. However, the two models did have similar goals, and enough interaction occurred among the designers of these standards that they emerged with a certain compatibility. In TCP/IP model, the protocols came first and the model was really just a description of the existing protocols.
