The OSI Model and The Pony Express Essay -- Essays Papers

The OSI baffle and The Pony pull upThe Open Systems Interconnection (OSI) reference representative is infixed to the world of electronic computer entanglementing. The model was created in 1977 by the International Standards Committee, in response to a difficulty that was facing computer networkers at the sequence (Shelly, Cashman, and Serwatka 142). In order to understand the difficulty, one must first get in that computer networks consist of computer hardware, the software that is to be used in conjunction with this hardware, and the medium (such as wiring or cabling) that will link the cypher devices that are in the network. The computer networkers job is to get which hardware, software, and medium types will create the network that will best pillow slip his clients needs. Then, the networker must unify these elements into a functional form of interconnected computers (Fortino and Villeneuve 112). It was in attempting this latter task that the computer networker of th e late mid-seventies often found himself in a pickle. The problem was that each(prenominal) trafficker of computing equipment had developed his own unique set of products products that were incompatible with the products of other vendors. This incompatibility made it very difficult for a computer networker to combine the various network components into an operational computer network (Stamper 27). The OSI model provided for a solution to this problem. The model organized those tasks that are essential for computer network operation, into seven groups. These groups were called layers. All manufacturers of computing equipment were recommended to make their products compliant with the OSI model. This meant that each computing product was to perform the functions associated with a specific layer within the model every method of accomplishing these functions was acceptable. In a network composed of equipment that operated match to OSI guidelines, a separate product would be used to perform each layer of OSI functionality. Thus, all elements of the network would be aware of the specific jobs performed by every other network element this would allow for compatibility between networking products that were created by different vendors. By designing networks according to OSI guidelines, the networker was able to combine any group of products, made by any number of vendors, into a mental process computer network (Stamper 28).... ...he secret of its success in the field of computer networking, and this is also the key to its use in other areas of communication as well.Works CitedDerfler, Frank J., Jr., and Les Freed.
