Vadzidzi, unyanzvi hwehutano, vashandi vekambani, uye chero ani zvake anofarira inyanzvi yekombiyuta yemakombiyuta anogona kubatsirwa nekudzidza zvakawanda pamusoro peOSI network model . Iko muenzaniso ndiyo yakanaka yekutanga yekunzwisisa zvivako zvemakombiyuta semashanduri, shandura uye maitiro emitambo .
Kunyange zvazvo matanho ezuva ranhasi achinyatsotevera kutevera magungano akaiswa nemuenzaniso weOSI, kufanana kwakakwana kunobatsira.

Ndeapi mamwe mazano anobatsira ekuyeuchidza mazamu eOSI?
Vadzidzi vanodzidza mitambo vanowanzoomerwa nokuyeuka zita roga roga roga yeOSI network model mune zvakakodzera. OSI munemonics ndiyo mitsara umo shoko rimwe nerimwe rinotanga nemagwaro akafanana neOSI inoenderana nemafambiro. Semuenzaniso, Vanhu Vose Vanoona Kuda Data Dzakaitwa "ndiyo inowanzoonekwa pamwonesi painoona mitambo yepamusoro-kusvika-pasi, uye Ndapota Usakanda Miti Yakagadzirwa Nayo Inowanzoonekwawo mune imwe nzira.
Kana zviri pamusoro zvisingabatsiri, edza imwe yeiyo mamwe mimweyumu kuti ikubatsire kuchengeta maitiro eOSI maitiro. Kubva pasi:
- Vadzidzisi havafaniri kukanda masaisai Pretzels Away
- Vanhu Havadi Kuona Paula Abdul
- Vanhu Vanoda Zvikuru Kuona Pamela Anderson
- Ndapota Usasangana Nzvimbo Yomukati Yakakwirira
- Ndapota Usatora yangu Samsung Phone Application
- Ndapota Usaudza Vanhu Kutengesa Chinhu
- Ndapota Usavimba Nekutengesa Vanhu 'Mhinduro
- Paula Akaita Networking Kusvikira Akapfuura
Kubva kumusoro:
- Yakave Yakanyatsojeka Ikorogiramu Yakagadzirirwa Pasi Panyama

Chii chinonzi Protocol Data Unit (PDU) chinoshandiswa pane imwe nheyo yakadzika?
The Transport layer packages data muzvikamu zvekushandiswa ne Network Network.
The Network layer packages data in packets inoshandiswa neData Link layer. (Internet Protocol, somuenzaniso, inoshanda ne IP packets.)
The Data Link layer packages data mufaira kuti ishandiswe nehutano hwepanyama. Izvi zvinosanganisira maviri sublayers ye Logical Link Control (LCC) uye Media Access Control (MAC).
Icho chimiro chemuviri chinoronga data muzvibhakera , zvishoma nezvishoma zvekutapura pamusoro pemutambo webhudhiyo.

Ndezvipi zvidimbu zvinokanganisa kuonekwa nekugadzirisa mabasa?
The Data Link layer inoshandisa kukanganisa kutadza pamapakiti anouya. Masoja anowanzoshandisa maitiro e-cyclic redundancy check (CRC) kuti awane ruzivo rwakashata pane ino.
The Transport kutarisa kunobata kukanganisa kupora. Icho chinozopedzisira chichigadzirisa dambudziko rakagamuchirwa nenzira uye pasina ruswa.

Pane kune dzimwe nzira dzakasiyana-siyana kune OSI network model?
Nzira ye OSI yakakundikana kuva inharaunda yose yepasi rose nekuda kwekugamuchirwa kweTCP / IP . Panzvimbo pokutevera maitiro eOSI zvakananga, TCP / IP yakatsanangura imwe nzira yekuvakira yakabva pamativi mana panzvimbo pechinomwe. Kubva pasi kusvika kumusoro:
- Network Access
- Kutakura
- Internetwork
- Kushanda
TCP / IP muenzaniso wakazogadziriswa kuparadzanisa Network Access yakasiyana muZviviri neDhina Link zvigadziro, zvichiita mhando yechishanu yepamusoro panzvimbo yechina.
Izvi zvikamu zveMutambo uye ZveDhina zvinowirirana zvakafanana nezvikamu zvakafanana 1 ne2 zvemufananidzo weOSI. IInternationalwork neTatereti zvinyorwa zvinowirirana zvakananga kune Network (layer 3) uye Kutakura (nhete 4) zvikamu zve OSI model.
Inoshandiswa sarudzo yeTCP / IP, zvisinei, inoparadzanisa zvakanyanya zvikuru kubva mufananidzo weOSI. MuTCP / IP, izvi zvinowanzoita mabasa ezvikamu zvitatu zvepamusoro-soro muOSI (Session, Presentation, uye Application).
Nemhaka yokuti TCP / IP model yakarongeka pane zvishoma zvinyorwa zveprotocols kutsigira kupfuura OSI, chivakwa chacho chinonyanya kurongerwa kune zvido zvayo uye maitiro ayo haafani zvakananga neOSI kunyange nematombo ezita rimwe chete.
