Ngiyaqiniseka ukuthi unazo Intambo ye-UTP ekhaya futhi angazi kahle ukuthi kuyini. Sisebenzisa i-inthanethi nsuku zonke cishe kuzo zonke izimo ezimpilweni zethu. Uma ungakukholwa, bheka ikhaya lakho futhi uzobona izinhlobonhlobo zamadivayisi axhunywe ku-inthanethi.
Ukuze ube nenethiwekhi (yasekhaya) ezinzile, kuyanconywa ukuthi uxhume amadivayisi ethu ngentambo ye-UTP. Lena intambo yenethiwekhi eklanyelwe ukudluliswa kwedatha kanye nocingo. Ngakho-ke, umsebenzi wayo oyinhloko ukuxhuma amadivaysi komunye nomunye kanye/noma i-inthanethi. Ake sifunde kabanzi ngalolu hlobo lwekhebula.
Iyini ikhebula le-UTP?
Isifinyezo se- Intambo ye-UTP okuka "ipheya elisontekile elingavikelekile". Ngaphakathi kwekhebuli ye-UTP, uzothola izintambo eziyisishiyagalombili ezihlukene. Zonke izintambo zisontekile zaba ngamapheya amane. Isixhumi singabekwa ekugcineni kwalezi zintambo. Lezi zixhumi zaziwa nangokuthi ama-RJ45 plugs.
Isebenza kanjani ikhebula le-UTP
El Intambo ye-UTP inomsebenzi we dlulisa isignaliUkuze kuvinjelwe ukonakala, ahlanganiswa abe ngamabili, okuholela ekubeni izintambo eziyisishiyagalombili ezihlukene ezisontekile zibe ngamapheya amane ahlukene. Izintambo ezimbili ezingazodwana kupheya zisonte ndawonye, bese kuthi amapheya asontwe ndawonye. Lokhu kwenzelwa ukunciphisa ukuphazamiseka kwe-electromagnetic.
Isisekelo ukuphazamiseka ingehlisa ukusebenza kwenethiwekhi. Isignali ngayinye kupheya esontekile idinga izintambo zombili. Amapheya asontekile anekhodi yombala ukwenza kube lula ukuhlonza ipheya ngayinye.
Ngokuvamile, ipheya elilodwa linocingo olulodwa olunombala oqinile kuyilapho ipheya yesibili iqukethe imigqa embala wozakwethu.
Isibonelo, intambo eluhlaza okwesibhakabhaka eqinile ingabhangqwa nocingo olunemigqa eluhlaza okwesibhakabhaka nomhlophe. Lokhu kwenza kube lula ukukhomba nokubhanqa.
Izigaba zekhebula le-UTP
Kunezinhlobonhlobo zezigaba zezintambo ze-UTP. Ukuqala nge-Cat5 (isigaba 5), manje sesingakwazi ukusebenzisa i-Cat7. Futhi akugcini lapho, njengoba phakathi kwalezi zigaba kukhona ezinye izinhlobo ezahlukene zezintambo ze-UTP.
Isibonelo, asinayo i-Cat5 kuphela, kodwa futhi ne-Cat5e.
La umehluko phakathi kwalezi zigaba ahlukene ama-bandwidths ukuthi izintambo zingasebenza ngazo. Isibonelo, i-Cat8 inokudluliswa kwedatha okuphezulu kakhulu.
Ngezansi ungathola ukubuka konke kwamakhebuli ahlukene nesivinini esihambisanayo:
Ingabe ikhebula le-UTP liyafana ne-Ethernet?
Kuyinto evamile ukuba abantu ikhebula le-ethernet ku-UTP ngoba wonke amanethiwekhi alandela izindinganiso ze-IEEE zekhebula ye-Ethernet. Izinga lokuqala le-Ethernet lasungulwa ngu-Xerox ngawo-1970. Manje isiphethwe yi-IEEE (Institute of Electrical and Electronics Engineers), iqembu elisebenzayo elithuthukisa amazinga amanethiwekhi e-Ethernet.
Ukwengeza, abathengisi bavame ukukhangisa i-UTP njengezintambo ze-Ethernet. Izintambo ze-UTP yizintambo ezivame kakhulu ezisetshenziswa kumanethiwekhi futhi zikhonjwe eduze njengezintambo ze-Ethernet.
