- The model was developed by the ISO (International Organisation for Standardisation) in 1984. It is currently considered the primary Architectural model for inter-computer communications.
- The OSI (Open Systems Interconnection) reference model is a descriptive network scheme. It makes sure greater compatibility and interoperability between various types of network technologies.
- The OSI model describes how information or data makes its way from application programmes (such like spread sheets) through a network medium (such like wire) to another application programme located on another network.
- The OSI reference model divides the difficulty of moving information between computers over a network medium into SEVEN smaller and more manageable problems.
- This separation into lesser more manageable functions is known as layering.
