Izinga elifanelekayo le-broadband lihlukile ngamazwe
Igama elithi "broadband" lisho ngokuqondile kunoma yiluphi uhlobo lwezinqubo zokudlulisela isignali-noma luhlangene noma olungenazintambo-oluphethe izinhlobo ezimbili noma eziningi ezihlukene zedatha ngeziteshi ezihlukene. Ekusetshenzisweni okudumile, libhekisela kunoma yikuphi uxhumano lwe-intanethi oluphezulu.
Izincazelo ze-Broadband
Njengoba ukuxhumana kwenethiwekhi endala yokudayela ku-intanethi kuqale ukushintshwa ngezindlela ezintsha ezisheshayo, zonke izindlela zobuchwepheshe ezishayelwayo ngokuvamile zithengiswa njenge "intanethi ye-broadband." Amaqembu kahulumeni kanye nezimboni azame ukubeka izincazelo ezisemthethweni zalokho okuhlukanisa izinsizakalo ze-broadband kusuka ekungenabanzi obubanzi, ngokuyinhloko ngokusekelwe emazingeni aphezulu edatha asekelayo. Lezi zincazelo ziye zahluka ngokuhamba kwesikhathi futhi nangezwe. Ngokwesibonelo:
- EPhilippines, ukulanda amazinga we-256 Kbps afaneleke njenge-broadband (ngo-2016)
- E-India, isikhulumi esivumelekile se-broadband isivinini sikhulisiwe kusuka ku-256 Kbps kuya ku-512 Kbps okulandwayo ngo-2014.
- E-US, i-Federal Communications Commission ikhulise umkhawulo wayo wokulinganisa ngo-2015 kusuka ku-4 Mbps kuya ku-25 Mbps ukulandwa futhi kusuka ku-1 Mbps kuya ku-3 Mbps ukuze ulayishe. Ekuqaleni, emuva kuka-1999, i-FCC yabe isetha umthamo wayo wokubambisana nge-200 Kbps yokulandwa.
Izinhlobo ze-Broadband Network Technologies
Phakathi kobuchwepheshe bokufinyelela kwe-intanethi ngokuvamile obhekwa njenge-broadband yilezi:
- I-Digital Subscriber Line (DSL) - Isevisi ye-Intanethi ehlanganisa iziteshi zezwi nezethambile ezihlukile kunombolo eyodwa yocingo. Ku-DSL, ithrafikhi yezwi igcwalisa ukuphela okuphansi kwe-spectrum yemvamisa nedatha igcwalisa ukuphela okuphezulu.
- I-modem yekhamera - Isevisi ye-inthanethi ehlanganisa idatha ephakeme kakhulu ngezimpawu zevidiyo ezinikezwe ngaphezu kwemigqa ye-cable cable
- Ukuxhumeka kwe-Mobile - Ukuxhumana kwedatha ye-intanethi eyenziwe nge-Smartphones nakwamanye amadivayisi weselula kumanethiwekhi weselula
- I-Fiber Internet (FTTH) kanye nezinsizakalo ezingenaselula zokuxhumeka kwe-intanethi ezitholakele njenge-intanethi ye-broadband ngaphansi kwencazelo ethandwayo nakuba lezi zinkampani zithwala kuphela uhlobo olulodwa lomgwaqo wedatha olunikezelwe ekuxhumaneni kwe-intanethi
Amanethiwekhi asekhaya we-Broadband abelana nokufinyelela ekuxhumaneni kwe-broadband ye-intanethi ngokusebenzisa ubuchwepheshe bezinethiwekhi zendawo ezifana ne- Wi-Fi ne- Ethernet . Nakuba bobabili basebenzayo ngesivinini esikhulu, akukho nalokhu okubhekwa njenge-broadband.
Izinkinga Nge-Broadband
Abantu abahlala ezindaweni ezincane noma ezingathuthukisiwe bavame ukuhlupheka ngenxa yokuntuleka kwamasevisi e-broadband internet njengoba abahlinzeki banesisusa esincane sezezimali ezindaweni zokuhlinzeka ngamakhasimende angancani kakhulu. Izindawo ezibizwa ngokuthi amanethiwekhi omsakazo omasipala abanikezela nge-intanethi isevisi ye-intanethi kubakhile abakhelwe ezindaweni ezithile, kodwa lokhu kunokufinyeleleka okukhawulelwe futhi kubike ukuthi kubangele ukuhlukunyezwa ngamabhizinisi ohlinzeka ngemisebenzi yangasese.
Ukwakhiwa kwamanethiwekhi amanethiwekhi okufinyelela kwe-wideband broadband angabiza ngenxa yengqalasizinda enkulu kanye nemithetho yomkhakha ehilelekile. Izindleko zengqalasizinda eziphezulu zikwenza kube nzima kubahlinzeki bezinsizakalo ukwehlisa amanani okubhaliselwe kwabo futhi banikele ngokuthembekile amakhasimende ukuvinjelwa kokuxhumana abayifunayo. Esimweni esinzima kunazo zonke, abasebenzisi bangakhokhiswa imali ephezulu yokwengeza imali yokudlula imali yabo yenyanga yokunikezwa kwedatha noma insizakalo yabo ivalwe okwesikhashana.
