Answer preview

Open Systems Interconnection (OSI) can be defined as a reference model explaining how different applications can relay message over a network. Notably, a reference model can be described as a conceptual system for understanding associations. It is clear an open systems interconnection (OSI) reference model has the purpose of guiding developers and vendors so that the developed digital communication products and software programs will interoperate in addition to enhancing clear comparisons among the communication devices. Large number of vendors involved in telecommunications makes a recommendable trial to describe their services and products regarding to the OSI model.
