Unokufuna ukwazi ukuba yintoni i-OSI Model 7 Layers?
Ngaphambi kokuba singene kwimodeli ye-OSI, kufuneka siqonde isigama esisisiseko sothungelwano ukuququzelela le ngxoxo ilandelayo.
Amanqaku
I-node nasiphi na isixhobo sombane esiqhagamshelwe kuthungelwano, esifana nekhompyutha, iprinta, irutha, njl.njl. IiNodi zinokuqhagamshelwa enye kwenye ukwenza uthungelwano.
Ikhonkco
Ikhonkco ludibaniso olubonakalayo okanye olunengqiqo oludibanisa ii-nodes kwinethiwekhi, enokuthi ifakwe intambo (efana ne-Ethernet) okanye i-wireless (efana ne-WiFi) kwaye ingaba yi-point-to-point okanye i-multipoint.
Umgaqo-nkqubo
Iprothokholi ngumgaqo weendawo ezimbini kuthungelwano ukutshintshiselana ngedatha. Le migaqo ichaza i-syntax, i-semantics, kunye nongqamaniso lokudluliselwa kwedatha.
Uthungelwano
Inethiwekhi ibhekisa kwingqokelela yezixhobo, ezinjengeekhompyuter, iiprinta, eziyilelwe ukwabelana ngedatha.
I-Topology
I-Topology ichaza indlela ii-nodes kunye neekhonkco ezilungiselelwe ngayo kwinethiwekhi kwaye yinto ebalulekileyo yesakhiwo sothungelwano.
Yintoni imodeli yeOSI?
Imodeli ye-OSI (i-Open Systems Interconnection) ichazwa yi-International Organisation for Standardization (ISO) kwaye yahlula amanethiwekhi ekhompyutheni kwiinqanaba ezisixhenxe ukunceda unxibelelwano phakathi kweenkqubo ezahlukeneyo. Imodeli ye-OSI ibonelela ngolwakhiwo olusemgangathweni lwesakhiwo sothungelwano, ukuze izixhobo ezivela kubavelisi abahlukeneyo zinxibelelane.

5. Uluhlu lweSeshini
Ukulawula iiseshoni phakathi kwezicelo, uxanduva lokusekwa kweseshoni, ukugcinwa, kunye nokupheliswa.
6. Uluhlu lweNgcaciso
Phatha ukuguqulwa kwefomathi yedatha, ukufakwa kweekhowudi zoonobumba, kunye noguqulelo lwedatha ukuqinisekisa ukuba idatha ingasetyenziswa ngokuchanekileyo ngumaleko wesicelo.
7. Uluhlu lweSicelo

Imodeli ye-TCP / IP kunye ne-OSI imodeli eyahlukileyo
Nangona imodeli ye-OSI ingumgangatho wonxibelelwano wothungelwano lwethiyori, imodeli ye-TCP/IP ngowona mgangatho wothungelwano usetyenziswa ngokubanzi. Imodeli ye-TCP / IP isebenzisa i-hierarchical structure, kodwa inemigangatho emine kuphela (i-application layer, i-transport layer, i-network layer, kunye ne-link layer), ehambelanayo ngolu hlobo lulandelayo:
Umaleko wesicelo se-OSI <--> TCP/IP umaleko wesicelo
Umaleko wezothutho we-OSI <--> TCP/IP umaleko wothutho
OSI network layer <--> TCP/IP network layer
Umaleko wekhonkco lwedatha ye-OSI kunye nomgangatho womzimba <-> TCP/IP umaleko wekhonkco
Ke, imodeli ye-OSI enemigangatho esixhenxe ibonelela ngesikhokelo esibalulekileyo sokusebenzisana kwezixhobo zenethiwekhi kunye neenkqubo ngokwahlulahlula ngokucacileyo yonke imiba yonxibelelwano lwenethiwekhi. Ukuqonda le modeli akuncedi kuphela abalawuli bothungelwano ekuxazululeni iingxaki, kodwa ikwabeka isiseko sophando kunye nophando olunzulu lwetekhnoloji yenethiwekhi. Ndiyathemba ukuba ngale ntshayelelo, unokuqonda kwaye usebenzise imodeli ye-OSI nzulu ngakumbi.
