See more ideas about osi model, computer network and cisco networking. Open systems interconnection reference model osi model or osi seven layer model is a conceptual model that characterizes and standardizes the internal functions of a communication system by partitioning it into abstraction layers. Osi model concepts service says what a layer does interface says how to access the service protocol says how is the service implemented a set of rules and formats that govern the communication between two peers layering. This is effectively the manner in which they maintain an open channel between the two devices. Protocol encapsulation chart a pdf file illustrating the relationship between common protocols and the osi reference model.

The open systems interconnection osi model is a reference tool for understanding data. Each layer both performs specific functions to support the layers above it and offers services to the layers below it. The layers begin at the end user process application, layer 7 and work their way down through each layer until bits are put on the wire physical, layer 1.
