Network Layers (OSI Model)

Despite the success of the Internet in replacing all in all the preceding(prenominal) attempts to build a global computer communication system, near engineers havent updated their thinking from old descriptions of meshs. instead they st seedy cling to the out-of-date 7-layer reference copy that was invented by ISO instead of the 5-layer reference labor that was invented for the Internet. Interestingly, engineers who insist on using the older copy can non grade single protocol at layers 5 and 6. But... because they learned the model somewhere in school, they desparately hope that the extra layers must be useful. As a result, they incorrectly classify applications as as layer 7 instead of layer 5. Researchers have begun smell for into the origins and uses of the OSI 7-layer reference model to determine why a ill at ease(p) and inaccurate model has had such staying power. They have recently reveal some surprising facts. We have know for a vast time that the model was the work of a collection. We did not know, however, that the gathering met late one night in a restraint and began making fun of American pop cluture. As it turns out, they started scribbling call of the sevener overshadows from the Disney movie on a paper cocktail napkin, and person joked that seven was a really good material body for network layers. The next morning at the standards committee meeting, the group passed roughly the cocktail napkin and generally agreed that that they had discovered something rudimentary the old night while they were drunk. By the end of the day, they had renamed the seven layers (with label that sounded more scientific), and produced the basic model.
