Difference Between OSI and TCP/IP Reference Model
Even though there exists various similarities between the OSI and TCP/IP model such as both carry defined standard as a layer, both use a simple process to troubleshoot, etc but there also exists a few differences between the two models. The comparison of the OSI and TCP/IP reference model is explained here based on the various factors.
Difference between OSI and TCP/IP Reference Model
|Developed by ISO.||Developed by ARPANET.|
|It is only a reference model and no actual implementation is done on this model.||This model is used for the development of the internet.|
|Stands for: Open System Interconnection.||Stands for: Transmission Control Protocol/Internet Protocol.|
|The transport layer confirms the delivery of the packets.||The transport layer does not confirm the delivery of the packets.|
|A vertical approach followed.||A horizontal approach followed.|
|Presentation and Session layers are different.||Both are the same and included under the application layer.|
|Can be used to build models like TCP/IP.||Can not be used for model building.|
|The network layer can provide connectionless service as well along with connection service.||The network layer can only provide connectionless service.|
|There exists 7 layers.||There exists 5 layers.|
|Used very less compared to TCP/IP.||Highly used.|
What is OSI Reference Model?
OSI reference model stands for Open System Interconnection reference model. The ISO introduced this model. This is a reference model and hence is only being used for reference and no real work or implementation is done on this model. It is used to introduce and teach the concepts related to computer networking.
The Open System Interconnection reference model is a conceptual model used to define the computer packet transfer with the help of multiple layer protocols. The OSI model carries the following layers:
What is a TCP/IP Reference Model?
The TCP/IP reference model stands for Transmission Control Protocol/Internet Protocol. It is a reference model used to explain the connection of a computer in order to transmit data after connecting to the internet. A virtual network is created.
The TCP/IP model is used to secure a connection to have a highly reliable network connection where end-to-end bytes can be transferred through the internet. The Transmission Control Protocol Internet Protocol model initially carried four layers but with the modifications, it now carries 5 layers which are mentioned below:
- Network Interface
