Detailed explanation-1: -OSI (Open Systems Interconnection) is a reference model for how applications communicate over a network.

Detailed explanation-2: -The Open Systems Interconnection (OSI) model describes seven layers that computer systems use to communicate over a network. It was the first standard model for network communications, adopted by all major computer and telecommunication companies in the early 1980s.

Detailed explanation-3: -ISO stands for International organization of Standardization. This is called a model for Open System Interconnection (OSI) and is commonly known as OSI model. The ISO-OSI model is a seven layer architecture. It defines seven layers or levels in a complete communication system.

Detailed explanation-4: -The Open Systems Interconnection model (OSI model) is a conceptual model that characterizes and standardizes the communication functions of a telecommunication or computing system without regard to their underlying internal structure and technology. It consists of seven layers. Physical layer. Data Link layer.
