What is OSI?

OSI stands for Open System Interconnection and is an ISO standard for worldwide communications. OSI defines a networking framework for implementing protocols in seven layers. OSI defines seven layers of functions that take place at each end of a communication. Although OSI is not always strictly adhered to in terms of keeping related functions together in a well-defined layer, many products involved in telecommunication attempt to describe themselves in relation to the OSI model.
