El modelu de interconexión de sistemes abiertos (ISO/IEC 7498-1), más conocíu como “modelu OSI”, (n'inglés, Open System Interconnection) ye un modelu de referencia pa los protocolos de la rede d'arquiteutura en capes, creáu nel añu 1980 pola Organización Internacional de Normalización (ISO). Publicóse dende 1983 pola Unión Internacional de Telecomunicaciones (UIT) y, dende 1984 TCP/IP model - Simple English Wikipedia, the free encyclopedia The TCP/IP model (Transmission Control Protocol/Internet Protocol) is a model with four layers which is for both modelling current Internet architecture, as well as providing a set a rules that govern all forms of transmission over a network. DARPA, an agency of the United States Department of Defense,created it in the 1970s.It evolved from ARPANET, which was an early wide area network and a The Open Systems Interconnection model (OSI model) is a conceptual model that characterises and standardises the communication functions of a telecommunication or computing system without regard to its underlying internal structure and technology. OSI is an American progressive rock band, originally formed by Fates Warning guitarist Jim Matheos in 2002. Chroma Key keyboardist and vocalist Kevin Moore is the only other full-time member of the band. Open Systems Interconnection, (ISO 7498) a joint ISO and ITU-T standard for computer networks and communication protocols OSI model, a layered description for communications and computer network protocol design; OSI protocols; Open switching interval, a type of disconnect supervision in telecommunication The Open Systems Interconnection model (OSI model) is a method of thinking of computer networking in terms of abstraction layers. Different communication protocols with similar functions are grouped into different logical layers on the OSI Model.

根据建议X.200,OSI将计算机网络体系结构划分为以下七层,标有1~7,第1层在底部。 現“OSI/RM”是英文“Open Systems Interconnection Reference Model”的缩写。 第7層 應用層

Referenční model ISO/OSI vypracovala organizace ISO jako hlavní část snahy o standardizaci počítačových sítí nazvané OSI a v roce 1984 ho přijala jako mezinárodní normu ISO 7498. Kompletní text normy přijala také CCITT jako doporučení X.200. Idėja. OSI modelis aprašo 7 sluoksnius – funkcijų, naudojamų protokoluose, grupes. Kiekvienas sluoksnis naudojasi žemesnio sluoksnio paslaugomis ir teikia paslaugas aukščiau esančiam sluoksniui (pagal tradiciją, pirmas sluoksnis yra vaizduojamas apačioje).
