ADSL thev naus laus zis yog dab tsi thiab nws ua haujlwm li cas?
ADSL yog cov ntawv luv rau Asymmetric Digital Subscriber Line
(Asymmetric Digital Subscriber Kab)
Nws yog qhov kev pabcuam uas muab kev siv Is Taws Nem dav.
Nws yog hom sib txuas tshaj plaws ntawm DSL txuas uas siv cov xov hlau uas twb tau tso rau hauv kev pabcuam xov tooj thiab qhov no ua rau nws pheej yig thiab siv tau rau kev faib kev sib txuas Is Taws Nem rau hauv tsev, tshwj xeeb tshaj yog vim nws muab kev nrawm nrawm txog 30-40 zaug sai dua li ib txwm muaj dial-up modem kev sib txuas, thiab siv ntau qhov ntau zaus.
Hauv ADSL thev naus laus zis tsis tau them nqi raws sijhawm lossis ib qho nqi sib txuas yog li nws tuaj yeem raug hu ua thev naus laus zis ib txwm muaj, qhov twg lub khoos phis tawj tuaj yeem txuas nrog Is Taws Nem tas mus li los ntawm ADSL ntaus ntawv lossis txuas xov tooj cua.
ADSL txoj haujlwm ua haujlwm
Lub hauv paus ntsiab lus ntawm ADSL thev naus laus zis yog qhov yooj yim heev thiab cuam tshuam nrog xa cov ntaub ntawv los ntawm ib feem ntawm cov xov tooj tooj liab uas yog nyob rau ib txoj kab av tshwj xeeb;
Ntawd yog, cov tooj liab muaj peev xwm ntau dua li nws tau siv rau kev hu xov tooj xwb, yog li ADSL siv qhov chaw ntxiv no thiab faib ntau zaus hauv cov hlau tooj liab ua peb ntu.
Raws li rau thawj feem ntawm cov tooj liab nws yog rau cov zaus siv rau kev hu xov tooj xws li 300 txog 3400 Hz, uas yog hu ua POT (Plain Old Telephone) thiab tau sib cais tag nrho los ntawm ob ntu ntawm cov tooj liab hlau siv tshwj xeeb txiav cov cuab yeej uas ua kom ntseeg tau kev sib tham hauv xov tooj yog tias ADSL kev sib txuas tau nres vim li cas.
Thaum ntu thib ob ntawm cov xaim tooj liab yog cov ntaub ntawv sib kis, uas tau mob siab rau xa cov ntaub ntawv los ntawm tus neeg siv cov lus qhia mus rau lub network, lossis qhov hu ua rub tawm.
Ib feem peb ntawm cov tooj liab yog rau rub tawm, piv txwv li los ntawm lub network rau tus neeg siv, thiab nws yuav tsum tau sau tseg ntawm no tias rub tawm nrawm los ntawm lub network hauv kab ASDL ntau dua li qhov nrawm ntawm upload rau lub network thiab qhov no yog dab tsi lo lus asymmetric txhais tau tias.
Dab tsi yog cov yam ntxwv ntawm ADSL
● ADSL kev siv tshuab sib cais yog qhov muaj txiaj ntsig thiab muaj txiaj ntsig zoo.
● Nws yog cov cuab yeej siv txuas mus rau ib qho, txhais tau tias koj qhov kev sib txuas tseem nyob ruaj khov thiab tsis cuam tshuam los ntawm ib yam dab tsi tsuav tus kws muab Internet tsis nres ua haujlwm.
● ADSL muab kev ua tau zoo hauv internet piv rau ISDN lossis modem txuas nrog ADSL, koj tuaj yeem rub tawm cov ntawv thiab nplooj ntawv web thiab xa email sai dua. ntawm ADSL. Muaj txiaj ntsig zoo rau cov tuam txhab los txo tus nqi ntawm kev hu thoob ntiaj teb.
● Los ntawm kev siv cov kev pabcuam no, koj yuav tsis txhawj xeeb txog tus nqi ntxiv lossis lwm yam nyiaj ntxiv uas koj yuav raug, muaj tus nqi them txhua hli uas koj yuav tsum tau them thiab qhov ntawd yog txhua yam rau nws, yam tsis muaj koj li kev siv Internet cuam tshuam. nrog tus nqi koj yuav tsum tau them.
Dab tsi yog qhov tsis zoo ntawm ADSL
Txawm hais tias qhov zoo ntawm qhov kev pabcuam zoo no, nws tsis yog tsis muaj qee qhov tsis zoo, uas peb yuav hais txog, uas yog:
● Qhov nrawm ntawm koj li ADSL kev sib txuas tau cuam tshuam los ntawm koj qhov deb ntawm lub chaw xov tooj, qhov siab dua qhov deb, qhov uas nws qaug zog. Qhov no ua rau ADSL tsis tsim nyog siv rau hauv cov chaw nyob deb nroog, qhov uas nws tsis muaj ntau zaus, thiab yog tias muaj nws feem ntau pluag.
● ADSL thev naus laus zis kuj cuam tshuam los ntawm cov neeg siv koj li kab, thiab yog tias muaj coob leej tuaj yeem ua rau pom kev qeeb, tshwj xeeb tshaj yog tias koj cov neeg nyob sib ze tseem muaj ADSL thiab muaj kev sau npe nrawm dua.
● Kev rub tawm nrawm los ntawm lub network yog ntau dua qhov nrawm ntawm kev xa mus rau lub network, qhov tseeb qhov no yuav suav tias yog qhov phem loj rau cov tib neeg uas xa cov ntaub ntawv hla lub network tas li, thiab cov neeg uas muaj cov vev xaib uas tshaj tawm lawv tas li.
Cost Tus nqi ntawm adsl yuav raug hloov pauv ntau vim tias cov muab kev pabcuam hauv internet muaj cov kev pabcuam txaus rau tus lej tshwj xeeb, tabsis qhov kev thov nce ntxiv yog yuam kom lawv nthuav lawv cov kev pabcuam thiab qhov no yuav raug nqi ntau, yog li tus nqi yuav raug hloov pauv thiab qhov no yog qee yam uas cov muab kev pabcuam tsis piav qhia rau cov neeg siv khoom
Thiab koj nyob hauv kev noj qab haus huv zoo tshaj plaws thiab kev nyab xeeb ntawm peb cov neeg nyiam
