Difference between OSI and TCP/IP model (OSI vs TCP/IP Model): The primary difference between OSI model and TCP/IP model is that the OSI model splits functions into numerous layers, whereas the TCP/IP paradigm consolidates them into a single layer.
OSI and TCP/IP reference models differ greatly in that OSI provides quality service whereas TCP/IP does not conform to this concept.
The establishment of a link between the sender and the receiver as well as the efficient transfer of data is achieved by the OSI model and the TCP/IP model.
Let us understand the OSI vs TCP/IP model and how the two differ from each other?
|OSI Model||TCP/IP model|
|The full form of OSI is (Open System Interconnection).||The full form of TCP is Transmission Control Protocol.|
|OSI model is developed by ISO (International standard organization).||TCP/IP model is developed by ARBANET (advanced research project agency network).|
|OSI Model has 7 layer:|
Data link Layer
|TCP/IP model has 4 layer:|
|OSI model works in vertical approach.||TCP/IP model works in horizontal approach.|
|The transport layer of OSI model give the confirmation of delivery of the packets.||The transport layer of TCP/IP model does not provide any confirmation of delivery of packets.|
|In OSI model function of session layer and presentation layers are separated.||But in TCP/IP model function of session layer and presentation layer is appears in the application layer.|
|In OSI model the network layer can be connect connection oriented as well as connectionless service.||But in TCP/IP model the network layer connects only in the connectionless service.|
|OSI mode has strict boundaries.||TCP/IP model does not have very strict boundaries.|
|In OSI, the model is developed before protocol of each layer.||In TCP/IP the protocols of each layer is developed before the model.|
|The protocols use in the OSI can be changed easily.||The protocols used in the TCP/IP cannot be changed easily.|
Similarities between TCP/IP and OSI model
Let’s understand the similarities between OSI and what are the important similarities you should learn?
- TCP/IP and OSI are the logical models that define networking standards.
- Both models divide networking concepts into different layers.
- Each network creates its own layers to divide the communication process.
- Both the OSI model and the TCP/IP model approach convert the raw data into packets and send them to the destination.
- A network layer and a transport layer are present in both models.
