Information processing systems - Open Systems Interconnection - Basic reference model
出版:Standards Australia

专家解读视频
Provides a common basis for the coordination of Standards development for the purpose of computer systems interconnection, while allowing existing Standards to be placed into perspective within the overall reference model. The reference model is based on a seven-layer view of computer systems: physical, data-link, network, transport, session, presentation and application. A system is considered an open system if it complies with the requirements of Open Systems Interconnection Standards in its communication with other computer systems. (Identical with ISO 7498:1984).
