What is the OSI Model?

[charlesprabhu]

Open Systems Interconnection, is a model for how applications communicate over a network and shows exactly what happens in each layer of a network system.

These capabilities are provided by a mixture of software and hardware that are used to transmit signals over wireless protocols (such as Wifi), fiber optic, or ethernet.

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.

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. In plain English, the OSI provides a standard for different computer systems to be able to communicate with each other. The OSI Model can be seen as a universal language for computer networking. It’s based on the concept of splitting up a communication system into seven abstract layers, each one stacked upon the last.
