Ezinsukwini zokuqala ze-intanethi, abahlinzeki be-intanethi yekhebula basekela ukuvinjelwa kwenethiwekhi ye-Broadband njengama-512 Kbps (0.5 Mbps ) okulandwayo. Lezi zivinini zenyukile eminyakeni edlule yi-factor of 100 ngokuthuthukiswa kobuchwepheshe be-Inthanethi.
Ikhebula lihlala linye yezinhlobo ezidume kakhulu zokufinyelela kwe-intanethi e-US, eCanada nakwamanye amazwe. Ilinganiswe ukuvinjelwa kokuxhumeka kwekhebula Ukuxhumeka kwe-inthanethi kuvame ukuphakama phakathi kwe-20 Mbps no-100 Mbps (enezinga langempela ledatha eliguquguqukayo kakhulu, kuye ngokuthi izihlinzeko nezimo zenethiwekhi).
Indima yeModemu yeChethri kwi-Internet Internet Speed
Ubuchwepheshe bekhomikhali yekhompiyutha bulandela izinga elijwayelekile le-Data Over Cable Cable Interface Specification (DOCSIS). Ama- modem amadala we-DOCSIS 2.0 asetshenziselwe ukusekela okulanda kufike ku-38 Mbps futhi alayishe kufika ku-27 Mbps. Lezi zimodemu zisebenze kahle ezinsukwini lapho abahlinzeki be-intanethi be-intanethi behlinzeka ngamasevisi okusebenza nge-10-15 Mbps noma amanani e-data aphansi.
Njengoba ubuchwepheshe bekhebula buye buphuthumayo, isidingo samamodeli wekhebula esheshayo saholela ekusungulweni kwe-DOCSIS 3.0, okukhulisa kakhulu ukusebenza komodemu uma kuqhathaniswa nezinguqulo zakudala ze-DOCSIS. I-DOCSIS 3.0 (ne-3.x) entsha ye-cable modems ingase isekele ukuvinjelwa kokuxhumeka kuka-150 Mbps. Abaningi abahlinzeki be-intanethi ye-intanethi manje bathengisa izinhlelo zesevisi ezigijima ngokushesha kunama-38 Mbps (ngokujwayelekile, ama-50 Mbps okulandwayo).
Abahlinzeki abakhulu bakathengisa noma baqashise imodemu ye-DOCSIS 3.0 ukuqinisekisa ukuthi amakhasimende abo afeze amazinga okusebenza afunayo kumanethiwekhi abo asekhaya. Abathengi bangakwazi futhi ukuthenga amamodemu abo uma bekhetha.
Izinto Ezinciphisa Ikhompyutha Inthanethi
Uyazi ukuthi ijubane lakho lekhebula lizohlukahluka kuye ngokuthi iphethini lokusetshenziswa labomakhelwane bakho? Ikhebula elilodwa lekhebula lixhuma emakhaya amaningi, futhi inani eliphelele le- bandwidth yenethiwekhi litholakale phakathi kwabhalisile kuleyo ndawo. Uma omakhelwane bakho abaningana befinyelela ku-intanethi ngesikhathi esifanayo, kungenzeka ukuthi ukuhamba kwekhebula (futhi nabo) kuzokwehla kakhulu phakathi nalezo zikhathi.
Uma kungenjalo, izimbangela ze-cable modem speed slowdowns zifana nalezo ze- DSL noma ezinye izinsizakalo ze-intanethi eziphezulu:
- I-glitch yesevisi: Ijubane lesikhamera lingadonsa ngokuzumayo uma umnikezeli wesevisi enenkinga yobuchwepheshe ngenethiwekhi yabo. Izinga kufanele zibuyele evamile ngemuva kwemizuzu embalwa noma amahora.
- I-capwidth cap : Abahlinzeki bangaphazamisa ukusebenza koxhumano lwe-Intanethi ngabanye ngokusekelwe emigomo yabo yesevisi. Ikhasimende elidlula isabelo sabo sanyangazonke sokuhamba komkhawulokudonsa, isibonelo, kungenzeka ukuthi isivinini sabo sokulanda esiphezulu sinciphise inani eliphansi kakhulu kunejwayelekile.
- I- router engalungile noma engasebenzi: I-Home routers ihlezi phakathi kwamakhompyutha wakho asekhaya nokuxhumeka kwe-intanethi. Uma ilayishiwe ngokweqile, ishisa kakhulu, noma isenasici, i-router ingakwazi kakhulu ukulinganisa ijubane lapho amadivayisi angasakaza khona noma alanda idatha kwi-intanethi.
- Ukuxhumeka okuphansi komzila: Ngenxa yokukhula kwesilinganiso esinamandla , ukuxhumeka okunye kwe-Wi-Fi kuklanyelwe ukusebenzisa ngaphansi kwe-10 Mbps ngaphansi kwezimo ezithile. Kungakhathaliseki ukuthi i-modem yekhebula ne-intanethi yayo ye-intanethi ijubane kangakanani, isivinini se-Inthanethi salowo divayisi sizokhawulelwa ngesixhumanisi se-Wi-Fi esincane.
- Izinkinga namadivayisi. Amakhompiyutha amadala kakhulu aswele amandla okucubungula okwanele noma imemori ayikwazi ukugcina ijubane nge-intanethi ye-intanethi. Amadivayisi angase abe nezinhlelo zokusebenza ezisemuva ezidlula lezi zinsiza.
Uma ikhebula lakho le-intanethi lingenzi ngendlela othanda ngayo, ukuxhumeka komhlinzeki wesevisi kungase kungabi imbangela. Ukuze uthole okwengeziwe, bheka lezi zeluleko zokuxazulula inkinga yokuxhumeka kwe-inthanethi .
