OSI Model
The Open Systems Interconnection model (OSI)is a conceptual model that characterizes and standardizes the inner functions of a communication gadget by way of partitioning it into abstraction layers. The model is a product of the Open systems Interconnection task on the international employer for Standardization (ISO), maintained by using the identification ISO/IEC 7498-1.
The model corporations conversation functions into seven logical layers. A layer serves the layer above it and is served via the layer under it. as an example, a layer that gives blunders-loose communications across a network offers the route needed by packages above it, whilst it calls the following decrease layer to send and acquire packets that make up the contents of that course. two instances at one layer are related by means of a horizontal connection on that layer.
