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

The OSI Model and The jog ExpressThe Open Systems Interconnection (OSI) honor qualified mention model is natural to the world of information processing system earningsing. The model was created in 1977 by the International Standards Committee, in response to a difficulty that was facing calculator communicateers at the time (Shelly, Cashman, and Serwatka 142). In order to understand the difficulty, one essential first realize that computer networks consist of computer hardware, the software that is to be apply in conjunction with this hardware, and the medium (such as wiring or cabling) that go out interconnect the computing 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 task tha t the computer networker of the late 1970s often found himself in a pickle. The task was that each vendor of computing equipment had developed his own unique sterilize of products products that were incompatible with the products of different 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 floors. All manufacturers of computing equipment were recommended to make their products teachable 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 wo uld be used to perform each layer of OSI functionality. Thus, all elements of the network would be apprised of the specific jobs performed by every other network element this would endure 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 reckon 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.
