Difference Between TCP/IP and OSI Model

The difference between TCP/IP and OSI Model seems to be minor but by composition, features, functions and purpose, the two are extremely different. The difference between the two terms is also important from the IAS Exam perspective. 

The TCP/IP or the Transmission Control Protocol/Internet Protocol is a communication protocol suite using which network devices can be connected to the Internet. On the other hand, the Open Systems Interconnection or OSI Model is a conceptual framework, using which the functioning of a network can be described. 

In this article, we bring to you a tabulated difference between the TCP/IP model and the OSI model. This will help candidates prepare themselves and upgrade their Computer Knowledge for the upcoming competitive exams.

TCP/IP vs OSI Model – Comparative Analysis

Given below is a tabulated comparison between the two models of networking, the TCP/IP and OSI model. Candidates must carefully go through the following key points of difference between the two. 

The above points of comparison display the difference between the TCP/IP and OSI models efficiently.

However, there are a few similarities between the two which are as mentioned below –

Similarities between the TCP/IP and OSI models

• Both models are based on layered structuring.
• In both models, data are mainly used to convert raw data into packets and help them reach their destination node. 
• In both models, protocols are defined in a layer-wise manner.
• The layers in the models are compared with each other. The physical layer and the data link layer of the OSI model correspond to the link layer of the TCP/IP model.
• The session layer, the presentation layer and the application layer of the OSI model together form the application layer of the TCP/IP model.
• The network layers and the transport layers are the same in both models.

It must also be known that the computer-based questions are asked in the Science and Technology part of the IAS syllabus. So, aspirants can also solve some sample Science and Technology MCQ for UPSC in the linked article.

Apart from the difference between TCP/IP and the OSI model, there are various other difference between articles which will enhance the Computer Awareness of the candidates. Below are links to a few such articles:

• Difference Between Search Engine and Web Browser
