Detailed explanation-1: -The open systems interconnection (OSI) model is a conceptual model created by the International Organization for Standardization which enables diverse communication systems to communicate using standard protocols.
Detailed explanation-2: -The acronym OSI stands for Open System Interconnection. This networking framework implements protocols in seven layers, hence the “7 layers of OSI model.” The Open System Interconnection is a reference model for how software applications communicate over a network.
Detailed explanation-3: -In the OSI reference model, the communications between a computing system are split into seven different abstraction layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application.
Detailed explanation-4: -In 1983, the CCITT and ISO documents were merged to form The Basic Reference Model for Open Systems Interconnection, usually referred to as the Open Systems Interconnection Reference Model, OSI Reference Model, or simply OSI model.
