Iimodem zeekhamera zidibanisa inethiwekhi yomzi kwindawo yokuhlala yecandelo leenkonzo ze-intanethi . Ezi modem zifakela kwi- router ebanzi kumxhelo omnye, ngokuqhelekileyo ngokusebenzisa ikhebula le- USB okanye ikhebula le- Ethernet , kunye ne-outlet yodonga (ekhokelela ekutyeni kwendawo yokutya).
Kwezinye iimeko, abathengi kufuneka bathenge ezi modem zekhebula ngokuthe ngqo , kodwa kwezinye iimeko azifanelekanga, njengoko kuchazwe ngezantsi.
I-DOCSIS kunye neeModems zeKhamera
I- Data Over Cable Cable Interface Specification (DOCSIS) isebenza ngokubanzi isekela amanethiwekhi ekhompyutheni ye-modem. Zonke iintambo ze-intanethi ze-intanethi zifuna ukusetyenziswa kweModem ehambisanayo ye-DOCSIS.
Iinguqulelo ezahlukeneyo ezahlukeneyo zeModems zeDOCSIS zikhoyo.
- Iinguqulelo ze-DOCSIS ze-1.0 kunye ne-1.1 zombini zenziwe zifumaneka ekupheleni kwee-1990. Ziphelile ngoku kwiindawo ezininzi zehlabathi. Ezi modem zixhasa ukufikelela kwi-38 Mbps zokulandwa kunye nokulayishwa kwe-9 Mbps.
- I-DOCSIS 2.0 isekela efanayo i-38 Mbps yokukhuphela i-1.x kodwa iyakwandisa ukuphakama komda wokudayela kwi-27 Mbps. Iimodem ezintsha zeD2x nazo zinokuxhasa i- IPv6 (tshekisha amaxwebhu emveliso ukuqinisekisa).
- I-DOCSIS 3 - iinguqulelo ze-3.0 kunye no-3.1 zonke inkxaso IPv6 kunye nenkxaso enxulumene ne-bandwidth ephezulu kune-D1.x / D2.x, ngaphezu kwe-100 Mbps. Zibuye zihambelane ngokuphindaphindiweyo kunye neenguqulelo zeDOCSIS kunye namanethiwekhi asekudala.
Ngokuqhelekileyo ufuna ukufumana i modem ye-D3 yekhefu ye-Intanethi. Nangona amaxabiso eemodemu ezintsha ze-D3 zingaba ziphakamileyo kuneenguqu ezidala, umlinganiselo wexabiso uye wancipha kakhulu kwiminyaka embalwa edluleyo. Iimveliso ze-D3 kufuneka zinike ixesha elide linomsebenzi kunokuba ziguqule, kwaye (ngokuxhomekeka kwindlela yokusetha inethiwekhi).
Qaphela ukuba abanikezeli be-intanethi baye bahlawula imali yabo yenyanga ngokumalunga neendleko zabo zenyanga. Hlola nomboneleli wakho ukuba unqume ukuba le nto ibalulekileyo kwisigqibo sakho sokuthenga.
Xa ungathengi iModem yeKharityhulam
Awufanele uthenge i-modem yekhebula yeyiphi na yezi zizathu ezintathu:
- Imimiselo yenkonzo yakho ye-intanethi idinga ukuba abathengi basebenzise kuphela iimodem ezinikezwa ngumboneleli
- Iphakheji yakho ye-intanethi idinga ukusebenzisa idilesi yesango elingenazintambo (ngaphandle kwe modem)
- mhlawumbi unokufudukela kwindawo eyahlukileyo kwaye ungalondoloza imali yokuqasha imodem (jonga ngezantsi)
Ukuqasha i Modem yeekhamera
Ngaphandle kokuba uceba ukufudukela kwindawo eyahlukileyo phakathi nonyaka okanye, ukuthenga i-modem yekhebula kulondoloza imali ngokukhawuleza ngokuqeshisa enye. Ngenjongo yokubonelela ngeyunithi abaqinisekisiweyo ukuba bayayifumana, ababoneleli nge-Intanethi bahlawula ubuncinane ubuncinane be-$ 5 USD ngenyanga ukubonelela iimodemu eziqashisayo. Iyunithi ingaba yinkqubo esetyenziswe ngaphambili, kwaye xa ithe yaphela ngokupheleleyo (okanye ingakumbi iqalisa ukwenza into ephosakeleyo), umniki-nkonzo unokukhawuleza ukuyifaka.
Ukuqinisekisa ukuba uthenge i-modem ebanzi ehambelana nenethiwekhi yomnikezeli we-Intanethi, khangela ukuba ngabahlobo okanye intsapho esebenzisa umlungiseleli ofanayo. Iziza zokunxibelelana nge-online kunye nezobuchwepheshe zigcina kwakhona uluhlu lweemodem ezihambelana nababoneleli abaziintloko. Thenga ityunithi esuka kumthombo owamkelayo ukubuya, ukuze ukwazi ukuzama nokutshintshana xa kuyimfuneko.
IiNdawo ezingenazintambo ze-Intanethi kwi-Intanethi
Abanye ababoneleli bebhanti banikezela abathengi babo iyunithi edibanisa imisebenzi ye-router engena-wire kunye ne-modem ebanzi kwidivaysi enye. Izango ezingenazintambo ezisetyenziselwa i-intanethi ye-intanethi zakhele imodemu ye-DOCSIS. Ukubhaliselwa kwiInternet, i-TV kunye neenkonzo zefoni ngamanye amaxesha zifuna ukusetyenziswa kwezi zixhobo endaweni yeemodem ezizimeleyo. Hlola nomboneleli wakho ukuba awuqinisekanga ngeemfuno zabo.
