OSI lachitsanzo

Gulu la akatswiri mu 1978, OSI zachitika muyezo. Akuti OSI chitsanzo si munthu zopezera muyezo. zidindo izi ukonde ndi nambala inayake ya misinkhu, imene onse anayamba machitidwe yovomerezeka. chitsanzo ichi amasonyeza mitundu ya ntchito network zimene ziperekedwa ndi mfundo zosiyana. Zisanu ndi wosanjikiza OSI maukonde chitsanzo ndi, inu mukhoza kunena, "Standard Standard". Akukwera chitsanzo ichi zafotokozedwa pansipa.

1. thupi

Maukonde wosanjikiza wa OSI chitsanzo ndi gawo m'munsi. Iye ali ndi udindo kwa thupi katundu wa maukonde, ndicho chingwe mtundu, kutalika chingwe, mtundu wa zolumikizira kuti ntchito zipangizo kulankhulana, etc. Mwazina, wosanjikiza izi ndi udindo magawo magetsi a chizindikiro kuti dongosolo amagwiritsa ntchito kutumiza deta pakati pa mfundo mu maukonde. Wamba ma siginalo ntchito kusonyeza dongosolo bayinare: 0 1.

2. Data Link Gulu

Mbali pa zimene Akamva mudziwe amawatumiza mfundo achikhalire, wotchedwa deta kugwirizana wosanjikiza wa OSI chitsanzo. motere mfundo pazikhalanso deta pa kukula kwa aliyense wa mapaketi anatumiza deta njira akulankhula nawo, ntchito kusamutsa katundu kuti tikafike anakhumba, ndi momwe troubleshoot kutumiza deta imodzi kuchokera mfundo angapo. Komanso amateteza dongosolo ku zolakwika.

3. maukonde chitsanzo OSI: Network Gulu

Pakuti kuonetsetsa kuti Intaneti kugwirizana ndi paketi yolozera mudziwe limafanana ndi wosanjikiza maukonde pakati pa Chiyuda. Pamene inu ntchito ndi iye safuna kuganizira za kusiyana miyezo pa machitidwe kugwirizana pa kugwirizana deta ndi milingo thupi.

4. maukonde chitsanzo OSI: Gulu Transport

Chimathandiza mgwirizano wa makompyuta awiri pa maukonde. Zinchito zake zikuphatikiza poika munthu aliyense maadiresi kompyuta ndi kasamalidwe kugwirizana mfundo.

5. maukonde chitsanzo OSI: gawo wosanjikiza

motere ntchito kuti athe kukhazikitsa gawo mgwirizano pakati pa mfundo zosiyana. Iye ndi amene kalunzanitsidwe ntchito zimene akuthamanga pa kompyuta osiyana. Kuchita izi, izo amalenga ulamuliro mfundo kulola yokonza zolakwa sititumiza deta onse kachiwiri, ndi kubwereza kutengerapo mfundo mfundo kulamulira, zomwe zayamba chifukwa cha cholakwa anali wapezeka.

6. chitsanzo maukonde OSI: ulaliki wosanjikiza

wosanjikiza Ichi ndi udindo akatembenuka mfundo opatsirana mu maukonde ku mtundu wina ku mtundu wina. motere amatha chitetezo deta kungodutsa, komanso decrypting mu lokonzekera mfundo ankafuna.

Gulu 7. Phunziro pankhaniyi

OSI lachitsanzo Iwo ali apamwamba msinkhu - kugwiritsa ntchito wosanjikiza, amene amathandiza kulankhulana ntchito ndi dongosolo maukonde. Mu mawu osavuta, ndi udindo kupeza mapulogalamu Intaneti. Pamaziko a ntchito wosanjikiza imagwiridwa mapulogalamu ntchito kuti imapatsa ku Internet (asakatuli), kulola nzeru deta (FTP-makasitomala ndi maseva) kusinthitsa mauthenga pa foni (makasitomala imelo) , ndi zina zotero.
