OSI Model Essay examples -- Essays Papers

OSI ModelDuring the past twain decades at that place has been a tremendous increase in the numbers and sizes of net clobbers. some(prenominal) of the networks, however, were built using different implementations of hardware and software. As a result, many a(prenominal) of the networks were incompatible and it became difficult for networks using different specifications to communicate with each other. To speech this problem, the International Organization for Standardization (ISO) researched many network schemes. The ISO recognized that there was a need to create a network clay sculpture that would serve well network builders implement networks that could communicate and work together (interoperability) and therefore, released the OSI reference model in 1984. This chapter explains how standards ensure greater compatibility and interoperability between various types of network technologies. In this chapter, you give learn how the OSI reference model networking scheme supports n etworking standards. In addition, you will see how information or data makes its way from masking programs (such as spreadsheets) through a network medium (such as wires) to other application programs located on other computers on a network. As you work through this chapter, you will learn about the basic functions that occur at each layer of the OSI model, which will serve as a introduction as you begin to design, build and troubleshoot networks. The concept of layers will help you view the action that occurs during communication from one compu...
