OSI Model Essay -- Computers Networking Technology Essays

OSI Model IntroductionSuccessful communication of whatever role contains four key characteristics. These characteristics follow 1. A sender This is the person who is direct in normalation. 2. A recipient This is the person the sender is sending the information to. 3. A common language If the sender and receiver be going to bring in each other, they will need a common language and protocol, or limited method of communicating. 4. A common medium The sender and receiver could choose whether to communicate in person, by telephone, writing or any other method that both can agree on. The OSI (Open Systems Interconnect) model attempts to place and standardize these key communication characteristics for computer entanglements. It does so by faulting communication between computers into seven specific moulds. Each lay er performs specific tasks relative to achieving communication. This paper will address the layers by explaining what they do severally and how they work together as a whole. Each OSI layer labels the lay out of data that it processes before passing it on to the next level. The next layer could be either above the circulating(prenominal) layer of below the current layer depending on whether the computer is receiving or sending data. For purposes of this paper, the layers will be described in top down fashion beginning with occupation and ending with the physical layer. This simulates the theoretical method that a computer sends data. When receiving data, the layers are reversed and the data flows from the physical up to the application layer. ... ...rk which companies use to split up network protocols. Each layer of the model was discussed separately. These layers are Application entry Sess ion Transport Network Data Link Physical protocol stacks allow computers to communicate with each other over the network even when they have different applications and operating systems.
