Ophunzira, akatswiri ochezera a pa Intaneti, ogwira nawo ntchito, ndi wina aliyense amene akukhudzidwa ndi zipangizo zamakono za makompyuta angapindule mwa kuphunzira zambiri za mtundu wa OSI . Chitsanzo ndicho chiyambi choyambira kumvetsetsa makina a makompyuta monga kusintha , maulendo ndi ma network .
Ngakhale makina amakono akutsatira mwatsatanetsatane ma msonkhanowo owonetsedwa ndi chitsanzo cha OSI, kufanana kokwanira kumakhala kothandiza.

Kodi ndi zina zotani zothandiza kukumbukira zolemba za OSI?
Ophunzira akugwiritsa ntchito mawebusaiti nthawi zambiri amakumana ndi zovuta kuloweza dzina la gawo lililonse la omangamanga la OSI molondola. OSI mnemonics ndi ziganizo zomwe mawu onse amayamba ndi kalata yomweyi monga momwe OSI imayendera. Mwachitsanzo, Anthu Onse Akuwoneka Kuti Akufuna Dongosolo la Dongosolo "ndilo lofala kwambiri pamene mukuwonera njira yachithunzithunzi pamwamba pa pansi, ndipo Chonde Musataye Pizza Kuchokera kumayendedwe.
Ngati chithunzichi sichithandiza, yesetsani zina mwaziwonetserozi kuti zikuthandizeni kuloweza malemba a OSI. Kuchokera pansi:
- Olemba mapulogalamu samayenera kuponya mchere Pretzels Kuchokera
- Anthu Sakufunikira Kuwona Paula Abdul
- Anthu Akufunikira Kwambiri Kuwona Pamela Anderson
- Chonde Musagwire Malo Osungirako Akuluakulu a Superman
- Chonde Musati Mukugwiritsira ntchito Samsung Phone Application
- Chonde Musauze Anthu Opanga Chilichonse
- Chonde Musakhulupirire Kubweretsa Anthu 'Mayankho
- Paula Anagwiritsira Ntchito Intaneti mpaka Atadutsa
Kuchokera pamwamba:
- Njira Yophweka Yopangidwira Kwambiri Yogwedezeka Kwambiri Mthupi

Kodi Protocol Protocol Unit (PDU) ikugwiritsidwa ntchito pazomwe zili m'munsi?
Phukusi loyendetsa maulendo deta m'magulu ogwiritsidwa ntchito ndi Mtanda wosanjikiza.
Mapulogalamu otetezera Network amatengera mapaketi oti agwiritsidwe ntchito ndi Data Link layer. (Internet Protocol, mwachitsanzo, ikugwira ntchito ndi mapaketi a IP.)
Mndandanda wa Dongosolo la Data Link deta m'mafelemu ogwiritsidwa ntchito ndi wosanjikiza. Mndandanda uwu uli ndi ma sublayers awiri a Logical Link Control (LCC) ndi Media Access Control (MAC).
Thupi lachilengedwe limapanga deta muzitsulo , zomwe zimapangitsa kuti zitha kulumikizidwa pa intaneti.

Kodi ndi zigawo ziti zomwe zimapangitsa kuti anthu asamadziwitse komanso kuti azindikire?
Dongosolo la Data Link limapanga kuzindikira kolakwika pa mapake amalowa. Ma Network nthawi zambiri amagwiritsa ntchito njira zowonongeka za CRC (CRC) pofuna kupeza deta yosokonezeka pa msinkhu uwu.
Maulendo zosanjikiza zimagwira zolakwika zowonongeka. Potsirizira pake zimatsimikizira kuti deta imalandira bwino komanso yopanda chinyengo.

Kodi pali zitsanzo zina zachitsanzo cha OSI Network Network?
Mchitidwe wa OSI sunathe kukhala chikhalidwe cha padziko lonse chifukwa cha kukhazikitsidwa kwa TCP / IP . M'malo motsatira njira ya OSI molunjika, TCP / IP inafotokozera njira zina zojambula zochokera pazinayi zina m'malo mwa zisanu ndi ziwiri. Kuyambira pansi mpaka pamwamba:
- Kupeza Mapulogalamu
- Maulendo
- Ntchito za intaneti
- Ntchito
Chitsanzo cha TCP / IP chinayambanso kupatulira Network Access kukhala osiyana thupi ndi Data Link zigawo, kupanga asanu wosanjikiza chitsanzo m'malo anayi.
Zigawo zowonjezera za Thupi ndi Dongosolo zimagwirizana ndi zigawo zofanana 1 ndi 2 za mtundu wa OSI. Maofesi a Internet and Transport amayanjananso molingana ndi Network (gawo lachitatu) ndi Transport (magawo 4) a OSI chitsanzo.
Komatu njira yothandizira TCP / IP, imasiyanitsa kwambiri ndi oSI. Mu TCP / IP, gawo limodzili limagwira ntchito za zigawo zitatu zapamwamba mu OSI (Session, Presentation, ndi Application).
Chifukwa chakuti chitsanzo cha TCP / IP chinagwiritsidwa ntchito pazinthu zing'onozing'ono zothandizira kuti zithandizire kuposa OSI, zomangamangazo zimagwirizana kwambiri ndi zosowa zake ndipo makhalidwe ake sagwirizana ndendende ndi OSI ngakhale zigawo za dzina lomwelo.
