Overview#Open Systems Interconnection (OSI) is an effort to standardize computer networking that was started in 1977 by the International Organization for Standardization (ISO), along with the ITU-T
(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.
Open Systems Interconnection 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.
