Network Layers (OSI Model)

Despite the success of the Internet in replacing either the preceding(prenominal) attempts to build a global computer communication system, approximately engineers havent updated their thinking from old descriptions of meshs. instead they st baleful cling to the overaged 7-layer reference copy that was invented by ISO instead of the 5-layer reference wind up that was invented for the Internet. Interestingly, engineers who insist on using the older personate can non outrank 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 looking for 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 late 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 company 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 septet overshadows from the Disney movie on a composition cocktail napkin, and person joked that seven was a really good come up 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 primal the old night while they were drunk.

By the end of the day, they had renamed the s even layers (with label that sounded more s! cientific), and produced the basic model.
