Det finns vissa likheter och olikheter mellan dem. En av de största skillnaderna är att OSI är en konceptuell modell som inte praktiskt används för kommunikation, medan TCP / IP används för att upprätta en anslutning och kommunicera via nätverket. While some pure OSI protocol applications, such as X.400, also combined them, there is no requirement that a TCP/IP protocol stack must impose monolithic architecture above the transport layer. For example, the NFS application protocol runs over the eXternal Data Representation (XDR) presentation protocol, which, in turn, runs over a protocol called Remote Procedure Call (RPC). Whenever we implement a network and try to connect and communicate different devices over the network. We use either the OSI or the TCP/IP reference model.

En comparant les couches du modèle TCP/IP et du modèle OSI, la couche d’application du modèle TCP/IP est similaire aux couches OSI 5, 6 et 7 combinées, mais le modèle TCP/IP n'a pas de couche de présentation ou couche de session distincte.

In OSI model, the protocols came after the model was described.

Jämför med OSI-modellen. TCP/IP (Transmission Control Protocol / Internet Protocol) utvecklades av Department of Defense i USA som ett

The OSI model was developed by the International Organization for Standardization. There are 7 layers: Physical (e.g. cable, RJ45) The Open System Interconnection Model, more commonly known as simply OSI, is another model that can help break the TCP/IP suite into modules. Technically speaking, it is exactly the same as the TCP/IP model, except that it has more layers.

The TCP/IP model and OSI model are both conceptual models used for description of all network communications, while TCP/IP itself is also an important protocol used in all Internet operations. Generally, when we talk about layer 2, layer 3 or layer 7 in which a network device works, we are referring to the OSI model.

While TCP/IP is the newer model, the Open Systems Interconnection (OSI) model is still referenced a lot to describe network layers.

It was designed to describe the functions of the communication system by dividing the communication procedure into smaller and simpler components. At the same time, the TCP/IP model connects various computers. The header size of OSI is a minimum of five bytes. In comparison, the TCP/IP model header size is twenty bytes. These are some of the basic differences between the OSI and TCP/IP conceptual model used for network transmission and communication. Figure 4 : Modèle OSI vs.

I praktiken har TCP/IP ersatt OSI som praktisk tillämpning av en öppen och oberoende standard för kommunikation. OSI har till stor del blivit just en referens. TCP/

It’s not meant to be an exact science, but rather a guide to help us visualize what happens during node-to-node communication. The Internet protocol suiteis the conceptual modeland set of communications protocolsused in the Internetand similar computer networks.

Layered Architecture: Both the OSI and TCP/IP model have a layered architecture. Each layer provides different functionalities in the network. The OSI model has generally 7 layers, …

Reading your last post/question, if you're also asking about the TCP/IP model, it's the 3rd layer (transport) of the 4 layers for that model. TCP/IP gains creditability because TCP/IP protocols are the standards around which the internet was developed despite the fact that networks are not generally built concerning the OSI model, just used as a guidance tool[3].The responsibilities of layers 5, 6 and 7 in the OSI model are handled by the application layer of TCP/IP.
