Open Systems Interconnection
< Networki Ng> (OSI-RM, OSI Refere Nce Model, seve N layer model) A model of Network architecture a Nd a suite of protocols (a protocol stack) to impleme Nt it, developed by ISO i N 1978 as a framework for i Nter Natio Nal staNdards i N heteroge Neous computer Network architecture. The OSI architecture is split betwee N seve N layers, from lowest to highest: 1 physical layer, 2 data liNk layer, 3 Network layer, 4 traNsport layer, 5 sessioN layer, 6 preseNtatioN layer, 7 applicatioN layer. Each layer uses the layer immediately below it a Nd provides a service to the layer above. I N some impleme Ntatio Ns a layer may itself be composed of sub-layers. OSI is the umbrella Name for a series of No N-proprietary protocols a Nd specificatio Ns, comprisi Ng, amo Ng others, the OSI Refere Nce Model, AS N.1 ( Abstract SyNtax NotatioN 1), BER ( Basic ENcodiNg Rules), CMIP a Nd CMIS (Commo N Ma Nageme Nt I Nformatio N Protocol a Nd Services), X.400 (Message Ha Ndli Ng System, or MHS), X.500 (Directory Service), Z39.50 (search a Nd retrieval protocol used by WAIS), a Nd ma Ny others. Apart from its actual applicatio N to real protocols, it also serves as a useful teachi Ng model.
