Osi seven-layer model in the 1980s, the european-dominated international standards organization (iso), began to develop its open systems interconnection (osi) networking suite. Well osi open system interconnecting reference model released in 1984 it has 7 layers and two running processes if the data is moving from layer 7 to layer 1 the process is. The osi (open system interconnection) model breaks the various aspects of a computer network into seven distinct layers each successive layer envelops the layer beneath it, hiding its. A layered network model • the osi reference model is composed of seven layers, each specifying particular network functions • the process of breaking up the functions or tasks of networking. What is the open systems interconnection (osi) reference model learn what the osi reference model is, why it was created and how the seven layers of the osi framework helps promote.
