    OSI Model Michael Hines NTC 360 Richard Bohn 29 November 2010 During the late 1970’s, the need for computers of all types to be able to communicate with each became more prevalent. In order to rectify this growing situation, the Internation Organization for Standardization (ISO) began to formulate the Open Systems Interconnection (OSI) model. The OSI model was created to standardize the rules of networking in order for all systems to be able to communicate. In order for communication...

    The Open Systems Interconnection (OSI) model (ISO/IEC 7498-1) is a conceptual model that characterizes and standardizes the internal functions of a communications system by partitioning it into abstraction layers. The model is a product of the Open Systems Interconnection project at theInternational Organization for Standardization (ISO). The model groups similar communication functions into one of seven logical layers. A layer serves the layer above it and is served by the layer below it. For...

    The OSI, or Open System Interconnection, model defines a networking framework for implementing protocols in seven layers. Control is passed from one layer to the next, starting at the application layer in one station, and proceeding to the bottom layer, over the channel to the next station and back up the hierarchy. The OSI model is not a real network architecture, because it does not really specify the services and protocols each layer should use. It rather describes what the layers must do....
