Open Systems Interconnection (OSI) definition

Open Systems Interconnection (OSI)

Set of protocols defined by ISO as the international standard computer network architecture. It takes a modular approach to network design that divides the required functions into seven self-contained, manageable, and functional layers, and is meant to interconnect equipment from different vendors. OSI, however, does not specify 'how' the systems should interconnect, it only defines interfaces for interconnection.
