When we are talking about layer 2 switches and layer 3 Ethernet switch, we are actually referring to the layers of a generic protocol model—Open Source Interconnect (OSI) model.

Also, the two models are different in their use of the layers. With TCP/IP, most apps make use of all four layers. Meanwhile, with the OSI model, only the first three layers (physical, data link, and network) are compulsory. The TCP/IP model was designed and developed by the US Department of Defense in the 1960s, based on basic protocols. The TCP/IP model is a compact version of the OSI model. TCP/IP is a short form of two protocols, namely Transmission Control Protocol and Internet Protocol which is a set of networking protocols which allows two or more computers The OSI Model for Anyone.

Denna kurs är uppbyggd kring OSI-modellen och förklarar i detalj hur nätverkskommunikation fungerar när TCP/IP används.

4. The Open System Interconnection model (OSI) is a seven layer m o del used to visualize computer networks. The OSI model is often viewed as complicated and many fear having to learn the model Se hela listan på itprc.com TCP (Transmission Control Protocol)/IP (Internet Protocol), is a protocol stack which was developed by DoD (Department of Defense). It was developed before the OSI Model. This model has 4 different layers. Like the OSI Model, different protocols are working at different layers. TCP/IP vs OSI. TCP/IP is about end-to-end data communication, providing the specifics on how data should be transmitted, addressed, packetized, routed, and ultimately received.

When you describe the way the Internet works, you don't always see all seven layers of the OSI Model as separate layers. The OSI Model is a seven layer design model and the Internet only needs a four layer model to OSI vs. TCP/IP Model.

The TCP/IP combines the OSI data link and physical into network access layer. OSI model is a reference model while TCP/IP is an implementation of OSI model. Technically speaking, no protocol from the TCP/IP stack has an official assignment to an OSI layer, because they're not of the same family. A reference model is just that, a reference.

TCP/IP vs OSI. TCP/IP is about end-to-end data communication, providing the specifics on how data should be transmitted, addressed, packetized, routed, and ultimately received. It involves four layers, namely the application, transport, internet, and link layers. This model consists of 4 layers.
