OSI model grade 7 Ben Walls Professor Shade NVCC The OSI, or the Open system Interconnection defines a networks framework that consists of 7 Layers. The Layers are in this order: Physical ( stratum1), data merge (layer2), Network (layer3), hold (layer4), Session (layer5), Presentation (layer6), and exercise (layer7). The OSI Layer 7 Governs the stay application-specific matters that are now covered by the session and founding layers.(Panko&Panko,Pg.74 Para.5) The OSI layer 7 is not in truth dominated by TCP/IP, although no standards agency unfeignedly dominates layer 7 the IETF (Internet Engineering Task Force) is pretty sacrosanct because of the importance of the polish off of Email and file transfer. as well at the Application layer (7) there is a ripening cooperation between ISO (International Organization for Standardization), the ITU-T(International Telecommunications Union-Telecommunications Standards Sector), and IETF. besides In VoIP The ITU-T and IETF have been functional closely, while ISO and IETF have been working with file format standards. The Application layer provides network serve directly to the users application such as a nett browser or netmail client. This layer is said to be closest to the user.

Protocols that go bad on this layer allow TELNET, HTTP, FTP, TFTP, SMTP, and NTP. http://www.techexams.net/technotes/networkplus/osimodel.shtml(2002-2011) I am convention from reading approximately Layer 7 (Application Layer) is that it is one of the most important layers in the OSI model, and that it is also closest to the user hence making i t the block off of the line as to speak. !
