Open Systems Interconnection (OSI) archetypeThis memorandum will attempt to explain the Open Systems Interconnection Model, known more simply as the OSI Model. The OSI Model has sevener levels, and these levels will be discussed in detail. Particular mention will be made to which level TCP/IP functions with the OSI Model.The seven levels of the OSI Model ar as follows7) Application Provides different services to the applications.6) Presentation Converts the discipline.5) Session Handles problems which are not communication issues.4) Transport Provides end to end communication control.3) Network Routes the information in the network.2) Data Link Provides error control between adjacent nodes.1) Physical Connects the entity to the transmission media.In simple terms, the OSI model defines a networking framework for implementing protocols. Is defines seven levels to accomplish this. Control is passed from one level to the next, starting at the Application level (Level Seven) and worki ng its way through the levels until it reaches and completes Level One, the Physical level. Once this pass has been completed, control moves to the next station on the network and back up the hierarchy.Since the process begins at the seventh level, the Application level, it will be detailed first. As its name implies, this Application level supports applications, but it also supports other end-user processes. User authentication and privacy on the network is consid...
