- 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.
Consider a simple wireless data link using channel bandwidth of 40 kHz. The transmit power level is 20 dBm, the link attenuation is 40 dB and the SNRdB at the receiver is 20 dB.
In spite of the incompatibilities among networks, researchers have devised a function that gives universal service among heterogeneous networks known 'internetworking'. It uses bot
