Mungafunike kudziwa kuti OSI Model 7 Layers ndi chiyani?
Tisanalowe mumtundu wa OSI, tiyenera kumvetsetsa mawu ena oyambira pa intaneti kuti tithandizire zokambirana zotsatirazi.
Nodes
Node ndi chipangizo chilichonse chamagetsi cholumikizidwa ndi netiweki, monga kompyuta, chosindikizira, rauta, ndi zina zambiri. Ma node amatha kulumikizidwa wina ndi mnzake kuti apange netiweki.
Lumikizani
Ulalo ndi kulumikizana kwakuthupi kapena koyenera komwe kumalumikiza ma node mu netiweki, yomwe imatha kukhala ndi mawaya (monga Efaneti) kapena opanda zingwe (monga WiFi) ndipo imatha kukhala yolunjika kapena yochulukirapo.
Ndondomeko
Protocol ndi lamulo la ma node awiri pa netiweki kusinthanitsa deta. Malamulowa amatanthauzira mawu, semantics, ndi kuyanjanitsa kwa kusamutsa deta.
Network
Netiweki imatanthawuza kusonkhanitsa kwa zida, monga makompyuta, osindikiza, omwe adapangidwa kuti azigawana zambiri.
Topology
Topology imalongosola momwe ma node ndi maulalo amapangidwira mu netiweki ndipo ndi gawo lofunikira pakupanga maukonde.
Kodi mtundu wa OSI ndi chiyani?
Mtundu wa OSI (Open Systems Interconnection) umatanthauzidwa ndi International Organisation for Standardization (ISO) ndipo umagawa maukonde apakompyuta m'magulu asanu ndi awiri kuti athandizire kulumikizana pakati pa machitidwe osiyanasiyana. Mtundu wa OSI umapereka zomanga zokhazikika zama network, kuti zida zochokera kwa opanga osiyanasiyana zizilumikizana.
Magawo asanu ndi awiri a mtundu wa OSI
1. Gulu Lathupi
Udindo wotumizira ma stream aiwisi, umatanthawuza mawonekedwe azinthu zowoneka ngati zingwe ndi ma siginecha opanda zingwe. Deta imafalitsidwa pang'onopang'ono pamtunda uwu.
2. Data Link Layer
Mafelemu a data amatumizidwa kudzera pa siginecha yakuthupi ndipo ali ndi udindo wozindikira zolakwika ndi kuwongolera kuyenda. Deta imakonzedwa mu mafelemu.
3. Network Layer
Ili ndi udindo wonyamula mapaketi pakati pa maukonde awiri kapena kuposerapo, kuwongolera njira ndi maadiresi oyenera. Deta imakonzedwa m'mapaketi.
4. Transport Layer
Amapereka kutumiza kwa data kumapeto mpaka kumapeto, kuonetsetsa kukhulupirika kwa deta ndi kutsatizana, kuphatikizapo kugwirizana kwa protocol TCP ndi protocol yosagwirizana ndi UDP. Deta ili m'mayunitsi a magawo (TCP) kapena ma datagram (UDP).
5. Gawo Lagawo
Sinthani magawo pakati pa mapulogalamu, omwe ali ndi udindo wokhazikitsa gawo, kukonza, ndi kuthetsa.
6. Gulu Lachiwonetsero
Gwiritsani ntchito kutembenuka kwa mtundu wa data, kubisa zilembo, ndi kubisa kwa data kuonetsetsa kuti datayo ingagwiritsidwe ntchito moyenera ndi wosanjikiza wa pulogalamuyo.
7. Ntchito Gulu
Imapatsa ogwiritsa ntchito mautumiki achindunji, kuphatikiza mapulogalamu ndi ntchito zosiyanasiyana, monga HTTP, FTP, SMTP, ndi zina zambiri.
Cholinga cha gawo lililonse lachitsanzo cha OSI ndi zovuta zake zomwe zingatheke
Gawo 1: Gulu Lathupi
Cholinga: Zosanjikiza zakuthupi zimakhudzidwa ndi mawonekedwe a zida zonse zakuthupi ndi ma sign. Ili ndi udindo wopanga ndikusunga kulumikizana kwenikweni pakati pa zida.
Kusaka zolakwika:
○Yang'anani kuwonongeka kwa zingwe ndi zolumikizira.
○Onetsetsani kuti zida zogwirira ntchito zikuyenda bwino.
○Tsimikizirani kuti magetsi ndi abwinobwino.
Layer 2: Data Link Layer
Cholinga: Dongosolo la ulalo wa data limakhala pamwamba pa gawo lakuthupi ndipo limayang'anira kupanga chimango ndikuzindikira zolakwika.
Kusaka zolakwika:
○zotheka woyamba wosanjikiza mavuto.
○Kulephera kwa kulumikizana pakati pa node.
○Kusokonekera kwa ma netiweki kapena kuwombana kwamafelemu.
Gawo 3: Network Layer
Cholinga: Netiweki wosanjikiza ndi udindo kutumiza mapaketi ku adiresi kopita, kusamalira kusankha njira.
Kusaka zolakwika:
○Onetsetsani kuti ma routers ndi masiwichi akonzedwa bwino.
○Tsimikizirani kuti adilesi ya IP yakonzedwa moyenera.
○Zolakwika zamaulalo zitha kusokoneza magwiridwe antchito a gawoli.
Gawo 4: Gawo la Transport
Cholinga: Gawo lazoyendetsa limatsimikizira kutumiza kodalirika kwa deta ndikuyendetsa magawo ndi kukonzanso deta.
Kusaka zolakwika:
○Tsimikizirani kuti satifiketi (mwachitsanzo, SSL/TLS) yatha.
○Onani ngati firewall imatchinga doko lofunikira.
○Kufunika kwa magalimoto kumayikidwa bwino.
Gawo 5: Gawo la Gawo
Cholinga: Gawo la gawoli liri ndi udindo wokhazikitsa, kusunga ndi kuthetseratu magawo kuti atsimikizire kusamutsa deta pawiri.
Kusaka zolakwika:
○Onani momwe seva ilili.
○Tsimikizirani kuti masinthidwe a pulogalamuyo ndi olondola.
○Magawo akhoza kutha kapena kutha.
Gawo 6: Gulu Lachiwonetsero
Cholinga: Chiwonetserocho chimayang'ana nkhani zamasanjidwe a data, kuphatikiza kubisa ndi kubisa.
Kusaka zolakwika:
○Kodi pali vuto ndi dalaivala kapena mapulogalamu?
○Kaya mtundu wa data wasankhidwa bwino.
Gawo 7: Gawo la Ntchito
Cholinga: Chigawo cha ntchito chimapereka ntchito zachindunji za ogwiritsa ntchito komanso mapulogalamu osiyanasiyana omwe amayendetsedwa pagawoli.
Kusaka zolakwika:
○Pulogalamuyi idakonzedwa bwino.
○Kaya wogwiritsa ntchito akutsatira njira yoyenera.
Mtundu wa TCP/IP ndi kusiyana kwamitundu ya OSI
Ngakhale mtundu wa OSI ndi mulingo wolumikizirana pa intaneti, TCP/IP ndiyomwe imagwiritsidwa ntchito kwambiri pa netiweki. Mtundu wa TCP/IP umagwiritsa ntchito mawonekedwe a hierarchical, koma uli ndi zigawo zinayi zokha (zosanjikiza zogwiritsira ntchito, zosanjikiza zoyendera, zosanjikiza zamaneti, ndi ulalo), zomwe zimayenderana motere:
OSI ntchito wosanjikiza <-> TCP/IP wosanjikiza ntchito
OSI transport layer <--> TCP/IP yosanjikiza
OSI network layer <--> TCP/IP network layer
OSI data link layer and body layer <-> TCP/IP link layer
Chifukwa chake, mtundu wa OSI wokhala ndi magawo asanu ndi awiri umapereka chitsogozo chofunikira pakulumikizana kwa zida zama netiweki ndi machitidwe pogawa momveka bwino mbali zonse zolumikizirana pa intaneti. Kumvetsetsa chitsanzo ichi sikumangothandiza otsogolera ma netiweki kuthetsa mavuto, komanso kumayala maziko a kafukufuku ndi kufufuza mozama kwa teknoloji yapaintaneti. Ndikukhulupirira kuti kudzera m'mawu oyambawa, mutha kumvetsetsa ndikugwiritsa ntchito mtundu wa OSI mozama.
