A broadband modem yog hom khoos phis tawj modem siv nrog kev pabcuam hauv internet ceev. Peb hom broadband feem ntau yog cable, DSL (digital subscriber line), thiab wireless. Ib txwm siv computer modems, piv txwv li, txhawb qis-ceev dial-up internet, uas yog suav tias yuav luag tsis siv nyob rau hauv cov cheeb tsam uas muaj kev pab cuam broadband.
Lub ntsiab lus ntawm kev ceev nrawm sib txawv raws lub tebchaws, thiab qee qhov kev pabcuam DSL thiab wireless siv cov thev naus laus zis qub tuaj yeem poob qis dua cov kev txwv. Txawm li cas los xij, txhua yam suav hais tias yog broadband modems.
Wired Broadband Modems
A cable modem txuas lub khoos phis tawj hauv tsev (lossis network ntawm cov khoos phis tawj hauv tsev) rau cov kab hauv tsev rau kev sib txuas hauv internet. Standard cable modems txhawb ib tug version ntawm DOCSIS (Data Over Cable Service Interface Specification). Hauv qhov sib piv, DSL modem txuas rau thaj chaw, kev pabcuam hauv xov tooj rau pej xeem rau kev sib txuas hauv internet.
Ob lub cable thiab DSL modems pab xa cov ntaub ntawv digital hla cov kab ntawm lub cev tsim los rau kev sib txuas lus analog (suab suab lossis xov tooj cua). Fiber internet (piv txwv li, Verizon FIOS) tsis xav tau lub modem vim tias fiber ntau optic cables txhawb kev sib txuas lus digital.
Wireless Broadband Modems
Wireless modem li txuas nrog cov kev pabcuam hauv xov tooj ntawm tes feem ntau hu ua mobile hotspots (tsis yog yuav tsum tsis meej pem nrog Wi-Fi hotspots). Kev hais lus, koj tuaj yeem siv lub xov tooj smartphone ua lub wireless modem los txuas rau lwm lub cuab yeej hauv zos hauv tethering hom.
Kho cov kev pabcuam wireless broadband qee zaum xav tau lub modem rau kev sib txuas hauv tsev mus rau tus kws kho mob cov khoom siv xov tooj cua hauv zos; qhov no nyob ntawm cov cuab yeej technology.
Siv Broadband Modems
Zoo li lub thawv TV teeb tsa, ob qho tib si cable thiab DSL modems feem ntau yog muab los ntawm tus neeg muab kev pabcuam hauv internet, yog li nws tsis yog ib qho khoom siv uas koj yuav tsum mus yuav khoom ntawm koj tus kheej (txawm tias feem ntau cov chaw muab kev pabcuam tso cai rau koj mus yuav koj cov khoom. tus kheej yog tias koj xaiv). Broadband modems yog qee zaum tsim ua ke nrog broadband routers thiab muag raws li ib chav nyob, feem ntau hu ua lub rooj vag hauv tsev lossis cov rooj vag hauv tsev.
Thaum muab tso rau nyias, lub broadband modem txuas rau hauv is taws nem ntawm ib kawg thiab hauv tsev network ntawm lwm qhov. Qhov txuas modem-rau-router siv ib qho Ethernet lossis USB cable, nyob ntawm seb cov kev xaiv twg txhua lub cuab yeej txhawb nqa. Lub modem-rau-internet kev twb kev txuas siv ib tug xov tooj kab (DSL) los yog ib tug coaxial cable kab (rau cable modems).
Cov teeb meem kev sib txuas
Thaum Microsoft Windows pom qhov teeb meem nrog koj qhov kev sib txuas broadband, nws qhia cov lus zoo li no: "Koj qhov kev sib txuas broadband tab tom ntsib teeb meem kev sib txuas." Txawm hais tias cov lus hais tshwj xeeb rau modem, qhov yuam kev no tuaj yeem qhia lwm yam teeb meem xws li:
- teeb meem lossis ua haujlwm tsis zoo nrog lub router broadband.
- teeb meem kev sib txuas ntawm lub khoos phis tawj Windows thiab router.
- Ua haujlwm tsis zoo nrog lub modem.
Tsis zoo li routers, modems muaj ob peb qhov chaw thiab kev xaiv teeb meem. Feem ntau, cov thawj coj yuav tsum tso lub modem tawm thiab rov qab mus rau rov pib dua. Txhawm rau kom tau txais txiaj ntsig zoo tshaj plaws, lub zog ob qho tib si broadband modem thiab router tawm thiab ua ke.
