OSI model OSI model. The Open Systems Interconnection model (OSI model) is a conceptual model that characterizes and standardizes the communication functions of a telecommunication or computing system without regard to their underlying internal structure and technology. Its goal is the interoperability of diverse communication systems with standard protocols.

What Is Osteogenesis Imperfecta? Fast Facts: An Easy-to-Read Series of Publications for the Public Osteogenesis imperfecta (OI) is a disease that causes weak bones that break easily. It is known as brittle bone disease. Sometimes the bones break for no known reason. OI can also cause many other problems such as weak muscles, brittle teeth, and hearing loss. About 20,000 to 50,000 people in the United States have OI.

Wireless sensor network survey Summary. 1  The Open Systems Interconnect (OSI) model has seven layers. This article describes and explains them, beginning with the 'lowest' in the hierarchy (the physical) and proceeding to the 'highest' (the application). The layers are stacked this way: Application; Presentation; Session; Transport; Network; Data Link; Physical; PHYSICAL LAYER The physical layer, the lowest layer of the OSI model, is concerned with the transmission and reception of the unstructured raw bit stream over a physical medium.

OSI model In 1983, these two documents were merged to form a standard called The Basic Reference Model for Open Systems Interconnection. The standard is usually referred to as the Open Systems Interconnection Reference Model, the OSI Reference Model, or simply the OSI model. It was published in 1984 by both the ISO, as standard ISO 7498, and the renamed CCITT (now called the Telecommunications Standardization Sector of the International Telecommunication Union or ITU-T) as standard X.200.

ES-IS (End System-to-Intermediate System) ES-IS (End System-to-Intermediate System) ES-IS (End System-to-Intermediate System) is a routing protocol developed by the International Organization for Standardization ( ISO ) as part of their Open Systems Interconnection ( OSI ) model. In the OSI context, an end system (ES) is a node or user device; an intermediate system (IS) is a router . ES-IS allows a node or user device located in a particular subnetwork to determine the existence and availability of other nodes or user devices on the same subnetwork.
