Ngeentsuku zokuqala ze-Intanethi, abanikezeli be-Intanethi bexhaswa ngee-intanethi ze- intanethi eziphantsi kwe-512 Kbps (0.5 Mbps ) zokulandwa. Ezi zihambeli zandile ngaphezu kweminyaka ngeminyaka eyi-100 kunye nophuculo lwe-intanethi ye-intanethi.
Ikhefu lihlala linye yeentlobo ezidumileyo zokufikelela kwi-Intanethi kwi-US, eCanada nakwamanye amazwe. Ukulinganiswa kwexesha lokuxhamla kwe-intanethi Iintanethi ze-intanethi zihlala phakathi kwama-20 Mbps kunye ne-100 Mbps (kunye neerhafu zangoku kwedatha eziguquguqukayo, kuxhomekeke kumboneleli kunye neenethwekhi).
Indima yeModemu yeCompany kwi-Intanethi ye-Intanethi ye-Intanethi
Inkqubo yekhompyutheni yekhompyutheni ilandela umgangatho weshishini kwi-Data Over Cable Cable Interface Specification (DOCSIS). I-DOCSIS 2.0 yeemodemu zekhompyutheni zixhaswe ngokukhawuleza ukuya kuma-38 Mbps kwaye ilayishe ukuya kwi-27 Mbps. Ezi modem zisebenze kakuhle kwiintsuku apho abanikezeli be-Intanethi banika iiplani zenkonzo kunye ne-10-15 Mbps okanye ixabiso lemali ephantsi.
Njengoko iteknoloji yekhamera iphuculwe, imfuno yeemodem zekhefu ezikhawulezayo zakhokelela ekufakweni kwe-DOCSIS 3.0, eyandisa ngokuphawulekayo ukusebenza komodem xa kuthelekiswa neenguqu zeDOCSIS ezindala. I-DOCSIS 3.0 (kunye ne-3.x) entsha ye-cable modems inokuxhasa ukukhawuleza kokuxhumeka kwi-150 Mbps. Uninzi lweenkonzo ze-intanethi ze-intanethi ngoku zithengisa izicwangciso zenkonzo ezisebenza ngokukhawuleza kunezi-38 Mbps (ngokuqhelekileyo, i-50 Mbps zokulandwa).
Ababoneleli abaninzi bayathengisa okanye baqeshise i modemon ze-DOCSIS 3.0 ukuqinisekisa ukuba abathengi babo bafezekisa amanqanaba okusebenza abafunayo kumanethiwekhi abo asekhaya. Abathengi banakho ukuthenga iimodem zabo xa bekhetha.
Izinto eziye zinciphisa i-Intanethi ye-Intanethi
Ngaba wayesazi ukuba ikhefu lekhefu liyahlukahluka ngokubhekiselele kwindlela yokusebenzisa yabamelwane bakho? Ikhowudi enye yekhompyutha idibanisa kumakhaya amaninzi, kwaye i- bandwidth epheleleyo yenethiwekhi ekhoyo ikwabelwana ngayo kubhalisele kuloo ndawo. Ukuba ngaba abaninzi abamelwane bakho bafikelela kwi-Intanethi ngexesha elifanayo, kunokwenzeka ukuba ikhefu le-cable (wena kunye nabo) liza kuhlahlaka kakhulu ngexesha lalo maxesha.
Ngaphandle koko, izimbangela ze-modem ye-speed slowdowns zifana nezo ze- DSL okanye ezinye iinkonzo ze-intanethi eziphezulu:
- I-glitch yenkonzo: Isantya sekharityhulam sinokukhawuleza ukuwa xa umniki-nkonzo enenkathazo yobuchwepheshe kunye nenethiwekhi yabo. Ixesha kufuneka libuyele eliqhelekileyo emva kwemizuzu embalwa okanye iiyure.
- Ikhutshana le-Bandwidth : Ababoneleli bangakwazi ukuphazamisa ukusebenza komnxeba we-Intanethi ngokubhekiselele kwimimiselo yenkonzo. Umthengi ogqithisileyo isibonelelo sawo senyanga, umzekelo, unokufumana isivinini esikhulu sokukhuphela kwisithintelo esincinci kunesiqhelo.
- I-router engalunganga okanye engasebenzi: Ii-routers zasekhaya zihlala phakathi kweekhompyutha zakho kunye ne-intanethi. Ukuba ikhululiwe, idlulele, okanye iphosakeleyo, i-router inokukhawulela kakhulu isivinini apho amadivaysi angahambisa okanye alayishe idatha kwi-intanethi.
- Ukunxibelelana ngokukhawuleza kwi-router: Ngenxa yokuhamba kwezinga eliguqukayo , ukuxhamla kwe-Wi-Fi kulungiselelwe ukusebenza ngaphantsi kwe-10 Mbps phantsi kweemeko ezithile. Kungakhathaliseki ukuba i-modem yekhebula kunye ne-intanethi yayo ye-intanethi, i-intanethi ye-intanethi yelo fowuni iya kugqitywa yi-Wi-Fi.
- Imiba enezixhobo. Iikhompyutha ezindala kakhulu ezingenayo amandla okwenza okufanelekileyo okanye imemori ayikwazi ukugcina intambo nge-intanethi ye-intanethi. Izixhobo zinakho nokuba nezincedisi ezihamba kwimvelaphi ezisebenzisa ezi zixhobo.
Ukuba i-Intanethi ye-Intanethi ayiyenzi ngendlela okulindeleyo, unxibelelwano lomniki-nkonzo lunakho okanye aluyi kubangela. Ngaphezulu, jonga ezi ngcebiso malunga neengxaki zokunxibelelana kwe-intanethi .
