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

The OSI Model and The Pony ExpressThe Open Systems Interconnection (OSI) reference ensample is inseparable to the world of computer networking. The model was named in 1977 by the International Standards Committee, in response to a difficulty that was facing computer networkers at the time (Shelly, Cashman, and Serwatka 142). In order to understand the difficulty, one must first realize that computer networks consist of computer hardware, the software that is to be used in conjunction with this hardware, and the moderate (such as wiring or cabling) that will interconnect the computer science devices that are in the network. The computer networkers job is to determine which hardware, software, and medium types will create the network that will best suit his clients needs. Then, the networker must combine these elements into a functional system of interconnected computers (Fortino and Villeneuve 112). It was in attempting this latter proletariat that the computer networker of the late 1970s often found himself in a pickle. The problem was that each vendor of computing equipment had developed his own unique go under of products products that were incompatible with the products of new(prenominal) 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 any method of accomplishing these functions was acceptable. In a network composed of equipment that operated according 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 functioning 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.
