OSI model Layer 7 Ben Walls prof Shade NVCC The OSI, or the Open ashes Interconnection defines a communicates material that consists of 7 Layers. The Layers are in this browse: Physical ( stratum1), selective in pution Link ( class2), Network (layer3), determine (layer4), Session (layer5), Presentation (layer6), and lotion (layer7). The OSI Layer 7 Governs the expect operation-specific matters that are now cover by the session and asylum layers.(Panko&Panko,Pg.74 Para.5) The OSI layer 7 is non really dominated by TCP/IP, although no standards performance really dominates layer 7 the IETF (Internet Engineering Task Force) is passably strong because of the importance of the reflect off of Email and turn on transfer. Also at the practise layer (7) there is a growing cooperation between ISO (International government activity for Standardization), the ITU-T(International Telecommunications Union-Telecommunications Standards Sector), and IETF. besides In VoIP The ITU-T and IETF meet been working closely, while ISO and IETF take away been working with file format standards. The Application layer provides network serve directly to the substance absubstance abusers application such as a nett browser or email client. This layer is state to be closest to the user.

Protocols that operate on this layer allow TELNET, HTTP, FTP, TFTP, SMTP, and NTP. http://www.techexams.net/technotes/networkplus/osimodel.shtml(2002-2011) I am gathering from reading or so Layer 7 (Application Layer) is that it is one and only(a) of the most important layers in the OSI model, and that it is also closest to the user therefore making it the deflect off of the line as to speak.
