In this article, we will discuss the differences between OSI and TCP/IP models. Both models help us to understand the data flow between sender and receiver using different networking protocols. Let’s discuss both of them in more detail.
Below, a diagram will help you to understand both models in a better way.
Understand OSI vs TCP/IP Model in detail
In this table, we have discussed some major differences between TCP/IP and OSI models.
|S.No.||OSI Model||TCP/IP Model|
|1.||OSI Stands for Open System Interconnection.||TCP/IP stands for Transmission Control Protocol / Internet Protocol.|
|2.||7 Different Layers.||4 Different Layers.|
|3.||It is developed by ISO (International Standard Organisation)||It is developed by DoD (Department of Defense).|
|4.||Conceptual Model||Used in actual data transmission between different computers.|
|5.||It is a not Tangible model.||It is a Tangible Model.|
Although we have discussed both in separate articles, you can find the common details below.
TCP/IP is a protocol stack that was developed by the DoD (Department of Defense). It was developed before the OSI Model. Unlike the OSI model, it has 4 different layers. Network traffic is generated on the application layer by the source and then it follows all of the TCP/IP model layers and then it sends to the receiver. Below are the TCP/IP model layers:
OSI model has 7 different layers. Unlike TCP/IP Model, this model provides a conceptual view of data flow between various computers. However, this is not a practical model, so it does not have practical usage. Below are the OSI Model layers:
- Data Link

TCP/IP is a protocol suite, which is used during data transmission over the network. TCP/IP was developed by DoD and has 4 different layers. On the other hand, OSI is a reference model, which has 7 different layers. OSI helps us to understand the data flow between different protocols.
