It is commonly referred to as the open systems interconnection reference model, or the osi reference model this was a conceptual model describing the 7 layers of a networked system, and its goal was to help standardize the network communication between various systems. 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 its underlying internal structure and technology its goal is the interoperability of diverse communication systems with standard protocols.
At layer 1, the physical layer of the osi model is responsible for ultimate transmission of digital data bits from the physical layer of the sending (source) device over network communications media to the physical layer of the receiving (destination) device examples of layer 1 technologies include. The osi (open systems interconnection) model was created by the iso to help standardize communication between computer systems it divides communications into seven different layers, which each include multiple hardware standards, protocols, or other types of services.
