OSI Layer in computer network.

open Reference network model [of] OSI or of OSI Reference Model networking open for [is] a model of arsitektural network developed by body of International Organization Standardization for ( ISO) [in] Europe in the year 1977. OSI alone represent abbreviation of Open System Interconnection. This Model [is] referred [as] also with model " Model seven enduing OSI" ( OSI Seven model layer
Before appearance model reference of OSI, computer network system very depended to pemasok ( vendor). OSI cope [common/ public] standard form [of] computer network to support interoperatibilitas between different pemasok. In a[n big network usually there are a lot of different network protocol. Inexistence a[n [is] same protocol, making many peripheral cannot [is] communicating each other
this Reference model [at] its [is] it[him] addressed as bases to develop network protocols, even practically this gumption experience of failure. That failure because of some factor following * Standard model this reference, in comparison with model reference of DARPA ( Model Internet) developed by Internet Engineering Task Force ( IETF), very nearby. Model DARPA [is] protocol bases model of TCP / ip which is [is] popular to be used * this Reference model [is] assumed [by] very complex. Some function ( as does communications method of connectionless) assumed [by] less good, whereas other function ( like control flow and mistake correction) diulang-ulang [at] some coat * Growth of Internet and protocol of TCP / ip ( a real world network protocol) making OSI Reference Model become less enthused
Government of United States try to support protocol of OSI Reference Model in governmental network solution in the year 1980-an, with implementation some standard of[is so-called with Government Open Systems Interconnection Profile ( GOSSIP). Still. this effort [is] finally left in the year 1995, and network implementation using OSI

OSI Reference Model even also [is] finally seen [by] as a ideal model of logical koneksi which must happened [so that/ to be] data communications in network can take place. Some used protocol in the world of reality, a kind of TCP / ip, DECNET and IBM of Systems Network Architecture ( SNA) map protocol heap ( stack protocol) they are to OSI Reference

Structure seven enduing model of OSI, at the same time with unit data protocol in each coat
OSI Reference Model have seven enduing, namely as follows.
