<P> 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 . The model partitions a communication system into abstraction layers . The original version of the model defined seven layers . </P>
