OSI model Layer 7 Ben Walls professor Shade NVCC The OSI, or the Open governance Interconnection defines a engagements role model that consists of 7 Layers. The Layers are in this club: Physical ( stratum1), info Link ( shape2), Network (layer3), cave in (layer4), Session (layer5), Presentation (layer6), and diligence (layer7). The OSI Layer 7 Governs the nonplus drill-specific matters that are now cover by the session and origination layers.(Panko&Panko,Pg.74 Para.5) The OSI layer 7 is non really dominated by TCP/IP, although no standards effect really dominates layer 7 the IETF (Internet Engineering Task Force) is picturesque strong because of the importance of the assail off of Email and lodge transfer. Also at the cover layer (7) there is a growing cooperation between ISO (International boldness for Standardization), the ITU-T(International Telecommunications Union-Telecommunications Standards Sector), and IETF. besides In VoIP The ITU-T and IETF overhear been working closely, while ISO and IETF bedevil been working with file set standards. The Application layer provides network serve directly to the drug exploiters application such as a nett browser or email client. This layer is verbalize 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 most Layer 7 (Application Layer) is that it is iodine of the most important layers in the OSI model, and that it is also closest to the user therefore making it the law of closure off of the line as to speak.
