Cov chaw muab kev pabcuam hauv Is Taws Nem xauj cov qauv no rau cov neeg siv khoom, tab sis koj tuaj yeem yuav ib qho. Nov yog yuav ua li cas thiaj nrhiav tau ib qho uas ua tau raws li koj xav tau.
DOCSIS thiab Cable Modems
Cov Ntaub Ntawv Tshaj Tawm Cable Service Interface Specification (DOCSIS) tus qauv txhawb nqa cable modem tes hauj lwm. Txhua qhov kev sib txuas hauv xov tooj cua hauv internet xav tau kev siv DOCSIS-tshaj modem.
Peb qhov loj ntawm DOCSIS modems muaj nyob:
- DOCSIS versions 1.0 thiab 1.1 tau muaj nyob rau xyoo 1990s. Tam sim no lawv tau dhau los lawm hauv feem ntau ntawm lub ntiaj teb. Cov modems no txhawb nqa mus txog 38 Mbps downloads thiab 9 Mbps uploads.
- DOCSIS 2.0 txhawb tib yam 38 Mbps rub tawm nrawm li 1.x tab sis nce qhov siab tshaj plaws upload bandwidth rau 27 Mbps. Tshiab dua D2.x modems kuj txhawb IPv6. Xyuas cov ntaub ntawv khoom kom paub meej.
- DOCSIS 3.0 thiab 3.1 txhawb IPv6 thiab kev sib txuas bandwidth siab dua (dhau 100 Mbps) dua D1.x/D2.x. Cov modems no rov qab siv tau nrog cov laus DOCSIS versions thiab networks.
A D3 modem yog tsim nyog rau niaj hnub cable internet. Txawm hais tias tus nqi rau D3 modems tshiab tuaj yeem siab dua rau cov laus dua, qhov sib txawv ntawm tus nqi tau tsawg dua hauv ob peb xyoos dhau los. D3 cov khoom muab lub neej siv tau ntev dua li cov qauv qub thiab tuaj yeem ua kom muaj kev sib txuas nrawm dua li cov qauv qub.
Thaum Tsis Yuav Kabmob Cable
Tshawb xyuas koj cov ntsiab lus kev pabcuam hauv internet kom paub tseeb tias tus kws kho mob tsis xav kom koj siv cov khoom siv xwb. Tsis tas li, yog tias koj tab tom xav txog kev hloov pauv hauv cov chaw muab kev pabcuam hauv internet, koj yuav txuag tau nyiaj los ntawm kev xauj tam sim no.
Yuav lub cable modem los ntawm qhov chaw lees txais rov qab, kom koj tuaj yeem sim thiab pauv nws yog tias tsim nyog.
Xaiv Cable Modems
Kev yuav ib lub cable modem feem ntau txuag nyiaj hauv lub sijhawm ntev dhau kev xauj ib qho. Hauv kev xa rov qab rau kev muab ib chav tsev uas tau lees tias ua tau zoo, cov chaw muab kev pabcuam hauv internet feem ntau them tsawg kawg yog $ 5 toj ib hlis. Chav tsev yuav raug siv, thiab yog tias nws ua tsis tiav (lossis tshwj xeeb, muaj teeb meem tsis sib xws), tus neeg muab kev pabcuam tuaj yeem hloov kho qeeb.
Txhawm rau xyuas kom koj yuav lub broadband modem uas sib haum nrog koj tus kws kho mob hauv internet, xyuas nrog phooj ywg lossis tsev neeg uas siv tib tus kws kho mob. Cov khw muag khoom hauv online thiab cov chaw pabcuam thev naus laus zis kuj tseem khaws cov npe ntawm cov qauv siv tau nrog cov chaw muab kev pabcuam loj.
Upload thiab rub tawm nrawm yog nyob ntawm qhov txwv tau teev tseg los ntawm cov chaw muab kev pabcuam cable hauv internet thiab qib kev pabcuam.
Wireless Gateways rau Cable Internet
Feem ntau cov chaw muab kev pabcuam broadband muab cov chav uas sib xyaw ua haujlwm ntawm lub wireless router thiab broadband modem rau hauv ib lub cuab yeej. Cov rooj vag wireless no tau tsim-hauv DOCSIS modems.
Kev tso npe rau kev sib koom ua ke hauv internet, TV, thiab xov tooj yuav tsum siv cov khoom siv no tsis yog cov khoom siv nyob ib leeg. Zoo li standalone modems, lawv muaj rau kev yuav khoom los ntawm cov khw muag khoom ib txwm muaj. Tshawb xyuas koj tus kws kho mob lub vev xaib kom ntseeg tau tias muaj kev sib raug zoo.
Puas yog koj lub Cable Modem tau tshaj?
Yog tias koj tab tom txiav txim siab yuav lub modem, tshawb xyuas qhov sib haum nrog koj tus kws kho mob.
Ntau lub chaw muab kev pabcuam hauv internet muab cov npe thiab cov cuab yeej los xyuas seb lub modem koj xav tias puas haum rau lawv cov kev pabcuam. Qee qhov piv txwv yog:
