Umbuso we- 5-4-3-2-1 uhlanganisa iresiphi elula yokuklama kwenethiwekhi. Kungase kungabi lula ukuthola izibonelo ekusebenzeni, kepha lo mthetho uhlangana ngokucophelela izakhi ezimbalwa ezibalulekile zenkolelo yokuklama inethiwekhi futhi kuboniswe ukuthi kuwusizo kubafundi iminyaka eminingi.
Izizinda Zokuqhafaza Nokusabalalisa Ukusabalalisa
Ukuze uqondisise lo mthetho, kudingekile kuqala ukuqonda imiqondo ehlangene yezizinda zokulwisana nokulibaziseka kokusabalalisa . Izizinda zokubambisana ziyingxenye yenethiwekhi. Uma iphakethe le-inthanethi lidluliselwa phezu kwe- Ethernet , ngokwesibonelo, kungenzeka ukuthi elinye ipakethe elisuka emthonjeni ohlukile ukuze idluliselwe eduze ngokwanele ngesikhathi sokupakisha kuqala ukuze kubangele ukushayisana komgwaqo ocingweni. Isikhathi esiphelele sebanga lapho iphakethe likwazi khona ukuhamba futhi lingase libe ne-collide ngenye indawo yilapho i-collision domain.
Ukulibaziseka kokusabalalisa kuyisakhiwo somphakathi ( isib. , Ethernet). Ukulibaziseka kokusabalalisa kusiza ukuthi kunani umehluko wesikhathi phakathi kokuthunyelwa kwamaphakethe amabili kwisizinda sokuphikisana kusondele ngokwanele ukuze kubangele ukushayisana. Ukubambezeleka kokusabalalisa okukhulu, amathuba okwanda kwezingxabano.
Izigaba zenethiwekhi
Ingxenye i-subset ekhethekile ehleliwe yenethiwekhi enkulu. Imingcele yechungechunge lwenethiwekhi isungulwa ngamadivayisi afanele ukulawula ukugeleza kwepakethe ngaphakathi nangaphandle kwendawo, kufaka phakathi ama-routers , ukushintsha , ama-hubs , amabhuloho , noma izindlela eziningi ezithintekayo (kodwa hhayi okuphindaphindiwe okulula).
Abakhi bezinhlelo zakha amadivaysi amakhompyutha ahlobene ngokwahlukene ngokomzimba ngamaqembu. Lokhu ukuqoqa kungathuthukisa ukusebenza kwenethiwekhi nokuphepha. Ezingxenyeni ze-Ethernet, ngokwesibonelo, amakhompiyutha athumela amaphakethe amaningi okusakaza kwinethiwekhi, kodwa amanye amakhompiyutha athile atholakele wona.
Amagceke enethiwekhi nezintambo zikhonza izinhloso ezifanayo; kokubili ukudala iqembu lama-computer. Umehluko phakathi kwesigaba ne-subnet yile ndlela elandelayo: ingxenye yakha ukwakhiwa kwenethiwekhi, kanti i-subnet imane ilungiselelo le-software eliphakeme. Ngokuyinhloko, umuntu akakwazi ukuchaza i-subnet eyodwa ye-IP esebenza ngokunembile kuzo zonke izingxenye eziningi.
Izingxenye ezi-5 zale Mithetho
Umthetho we-5-4-3-2-1 ulinganisa ububanzi besizinda sokushayisana ngokunciphisa ukubambezeleka kokusabalalisa isikhathi esithile "esengqondo". Ukubusa kubhidliza ezindaweni ezinhlanu eziyinhloko kanje:
5 - inani lezinhlelo zenethiwekhi
4 - inani labaphindaphindiwe lidingekile ukujoyina izingxenye zibe yisizinda esisodwa sokulwisana
3 - inani lamagcekeni enethiwekhi anamadivayisi asebenzayo (athumela) axhunyiwe
2 - inani lamacandelo angenawo amadivayisi asebenzayo axhunyiwe
1 - inombolo yezizinda zokulwisana
Ngenxa yokuthi izakhi ezimbili zokugcina zeresiphi zilandela ngokwemvelo kwabanye, lo mthetho ngezinye izikhathi uyaziwa nangokuthi "umthetho we-5-4-3" omfushane.
