OSI MODEL - A way of representing the complexities of computer networking in a 7-layer model, ranging from the physical hardware of networking all the way up to how application programs talk to the network. The 7 layers are: physical, data link, network, transport, session, presentation, and application. The 7-layer OSI model can be used to help diagnose network problems. It is also used as a measurement of how well people know their networking. If you're looking for a job in networking, you should familiarize yourself with the OSI model. |
