OSI vs TCP/IP Model, Similarities and difference between OSI and TCP/IP model

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: Physical Layer Data link Layer Network Layer Transport Layer Session Layer Presentation Layer Application Layer	TCP/IP model has 4 layer: Network Layer Internet Layer Transport Layer Application 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.
