Qhov kev txiav txim siab qhov kev sib txuas ntawm koj txoj kev txuas thiab seb koj puas tuaj yeem kuaj xyuas internet
Lub cev siv broadband yog obviously qhov tseem ceeb tshaj plaws hauv kev nkag mus rau hauv Internet. Txawm li cas los xij, broadband yog xa tawm ntawm cov khoom siv sib txawv thiab hom tshuab txiav txim qhov ntau ntawm kev xa mus rau koj lub computer.
Ntau lwm yam tseem ceeb yuav txiav txim siab txog qhov sib txuas ntawm koj txoj kev txuas thiab. Tsis tas li, txhua yam ntawm no cuam tshuam tau sai npaum li cas koj tuaj yeem nkag mus tau cov ntaub ntawv, download tau cov ntaub ntawv, lossis tau txais e-xa.
Ceev Ntsig Zoo
Qhov kev sib txuas ntawm koj qhov kev txuas tseem pom tau tias qhov zoo tshaj ntawm qhov video koj tab tom saib lossis lub suab koj mloog. Txhua tus neeg tau muaj kev ntxhov siab qeeb tos txog ib zaj yeeb yaj kiab lossis zaj nkauj mus download tau lossis saib cov yeeb yaj kiab uas stutters thiab skips ntawm koj lub monitor.
Qhov phem tshaj plaws yog thaum koj tau txais cov lus qhia tsis txaus ntseeg "qhov no". Buffering tsuas txhais tau tias koj qhov kev txuas tsis tuaj yeem tswj cov kev ceev uas lub yees duab xa tuaj rau koj lub computer screen. Nws yuav tsum yog vim li cas tam sim no sau cov ntaub ntawv ua ntej nws tseem playback. Nws zoo ib yam li koj lub tshuab luam ntawv sau cov ntaub ntawv koj xa tuaj ntawm koj lub computer mus luam tawm.
Nyob ntawm daim ntawv thov uas koj siv, qhov kev sib txuas ntawm koj qhov kev sib txuas yuav ntau zaus txiav txim siab seb nws puas tseem muaj peev xwm los khiav cov ntaub ntawv kom zoo. Ib zaj yeeb yaj kiab tsis zoo yog tias nws tsis ua si li ob peb feeb. Yog li, yuav tsum ceev nrooj ntawm kev txuas zoo li cas koj thiaj yuav tsum tau ua tej yam dej num thiab khiav qee cov kev pab cuam?
Bandwidth Vs. Ceev
Muaj ob yam sib txawv los xav txog thaum ntsuas kev ua haujlwm . Bandwidth yog hais txog qhov loj ntawm txoj kab hauv qhov uas cov ntaub ntawv tau tsiv tawm hauv. Kev ceev yog hais txog tus nqi uas cov ntaub ntawv taug kev ntawm.
Siv qhov txhais no, koj tuaj yeem pom sai sai tias ib qhov loj dua bandwidth yuav tso cai rau kev qhia ntxiv, uas yuav ntxiv qhov nqi ntawm qhov uas nws mus.
Txawm li cas los xij, qhov no tsis tas txhais tau hais tias qhov kev sib txuas ntawm koj txoj kev txuas broadband yuav zoo ib yam li koj qhov bandwidth. Bandwidth tsuas yog hais txog qhov loj ntawm "yeeb nkab" uas nws yog kev mus ncig.
Piv txwv, peb hais tias koj nyob nraum xa cov ntaub ntawv ntawm 128 Kbps (kilobits thib ob). Yog tias koj pib hloov lwm cov ntaub ntawv nws yuav sib tw rau bandwidth thiab qeeb koj ceev. Yog hais tias koj nce koj bandwidth los ntawm kev ntxiv lwm 128 Kbps ISDN kab, koj thawj cov ntaub ntawv tseem yuav mus rau 128 Kbps, tab sis tam sim no koj tuaj yeem hloov ob cov ntaub ntawv ntawm 128 Kbps tsis muaj kev pab ceev.
Ib qho piv txwv yuav yog ib txoj kev loj nrog kev khiav ceev 65mph. Txawm hais tias ntau txoj kab khiav haujlwm ntxiv los tuav ntau lub tsheb, qhov kev txwv tsis pub tshaj yog 65mph.
Cov Chaw Pabcuam Ntxiv thiab Muaj Kev Tshaj Tawm
Rau cov laj thawj no, cov neeg muab kev pabcuam broadband tshaj tawm ua haujlwm ceev nyob rau ntau qhov chaw, tsis ruaj khov naj npawb. Qhov no ua rau nws nyuaj rau kwv yees yog ceev npaum li cas ib qho kev twb kev txuas yuav yog.
Cov neeg zov me nyuam paub tias lawv muaj peev xwm muab tau tus nqi ntawm bandwidth los tswj cov nqi ntawm cov ntaub ntawv. Lawv tsis paub tseeb thaum cov ntaub ntawv no yuav tsum tau mus ncig los yog thaum muaj kev xav tau tso rau hauv lub network.
Tsis txhob cog qoob loo uas yuav tsis muaj qhov tsis tu ncua, lawv muaj caij nyoog uas qis qis qis qis.
Piv txwv, ib lub chaw pabcuam loj muaj ntau qhov chaw muaj kev pabcuam hauv online uas muaj kev sib txuas lus (download / upload):
- 15 Mbps / 5 Mbps
- 50 Mbps / 25 Mbps
- 75 Mbps / 35 Mbps
Koj qhov kev txuas hlais yuav tsum poob rau hauv cov kev ntsuas uas teev rau cov pob khoom siv. Qhov kev siv bandwidth rau cov kev kawm no yuav tsum tsis txhob tsawg dua qhov siab tshaj plaws teev tseg.
Piv txwv li, koj tsis tuaj yeem muaj ceev tshaj 15 Mbps (megabits ib ob) nrog ib tug bandwidth ntawm 15 Mbps. Qee cov chaw muab kev pabcuam pub txog qee yam qeeb. Hauv no, qhov "mus txog" ceev yog qhov bandwidth, uas txhais tau hais tias qhov kev ceev koj yuav ua tau yog yuav qis dua.
Upload Vs. Download tau ceev
Hauv kev xav, tsis muaj qhov sib txawv ntawm kev xa tawm thiab kev muab cov ntaub ntawv tawm ntawm cov kev taw qhia ntawm cov ntaub ntawv xa mus. Qhov ceev koj qhov internet txuas ceev, ceev koj cov uploading thiab daus muaj peev xwm.
Upload thiab download speeds yog feem ntau yooj yim ntsuas thaum lawv muaj cov yeeb yam . Qhov no txhais tau tias download thiab upload speeds yog sib npaug rau ib leeg.
Thaum lub sij hawm download speeds feem ntau yog qhia los ntawm cov neeg muab kev pabcuam broadband, kev ceev ceev kuj yog ib qho tseemceeb. Qhov no yog qhov tseeb tshaj yog tias koj lub lag luam yog nyob ntawm kev xa cov ntaub ntawv loj mus rau cov kev pab cuam huab.
Download speeds yog feem ntau sai dua li upload speeds vim tias feem ntau cov neeg siv internet muab cov ntaub ntawv tawm hauv internet es tsis xa cov ntaub ntawv thiab cov ntaub ntawv mus rau hauv internet. Yog tias koj yog ib tus neeg siv uas muab cov ntaub ntawv loj los yog lwm cov ntaub ntawv, koj yuav tsum nrhiav kev ceev ceev ceev. Ntau tus neeg zov me nyuam tau yooj yim muab kev nce siab dua los ntawm kev txo qis qis thaum tswj tuav tib lub phiaj xwm dav.
Megabits thiab Gigabits
Qhov tsawg tshaj plaws hauv cov ntaub ntawv yog cov me ntsis. Ib tug byte yog sib npaug rau 8 khoom thiab ib txhiab bytes yog ib tug kilobyte. Ntau xyoo dhau los, qhov no yog qhov siab tshaj plaws ntawm kev ceev koj yuav tsum paub. Cov kev sib txuas ntawm dial-up tsis muaj ntau tshaj 56 Kbps.
Broadband ceev feem ntau ntsuas hauv megabits ib ob . Ib tug megabit yog sib npaug ntawm 1000 kilobits thiab nws tau nquag teev tias Mb lossis Mbps (xws li, 15 Mb lossis 15 Mbps). Cov kev cai ceev ceev yog nce zuj zus, nrog rau kev siv zog Gigabytes sai sai (Gbps) sai tsim cov qauv tshiab rau kev txhim kho kev lag luam thiab kev siv hauv tsev.
Lub Tshuab Twg Lawm?
Tam sim no koj tau txiav txim siab seb koj yuav tsum khiav cov ntawv koj xav tau, koj yuav siv cov xovtooj txuas uake ceev npaum licas?
Los ntawm nws cov ntsiab txhais, broadband yog ib qho kev sib txuas hauv high-speed hauv Internet uas yog ib qho tseem ceeb rau. Dial-up access, ntawm qhov tod tes, yuav tsum muaj modem los pib lub 56 Kbps kev twb kev txuas mus rau hauv Internet.
Tsoom Fwv Sib Txuas Lus (Federal Communications Commission) (FCC) tau tsa qis qis kawg ntawm kev xa xov mus rau 4 Mbps nqes thiab 1 Mbps ntws. Qhov no yog tam sim no tus txheej txheem tshiab rau qhov kev sib txuas khwv kom tsawg kawg broadband. Txawm li cas los xij, qhov no tsis txaus rau ntau cov kev siv, xws li streaming video services xws li Netflix.
Lub FCC tau piav tawm lub hom phiaj ntawm lub National Broadband Plan txog kev ua kom pom dav nrig. Ib ntawm Thawj Tswj Hwm Obama txoj kev siv hom phiaj loj tshaj plaws yog los txuas 100 lab tib neeg rau 100 Mbps nce mus txog 2020.

Yuav Ntsuas Koj Li Cas?
Yog hais tias qhov kev sib txuas ntawm koj qhov kev txuas yuav txawv dua li qhov koj tus neeg muab kev pab tshaj tawm, koj paub tias koj tau txais dab tsi tiag tiag? Lub FCC muaj cov tswv yim thiab lub chaw soj ntsuam los pab koj txiav txim siab yog tias koj tau txais qhov kev ceev koj tau them rau.
Lwm qhov kev xaiv yog siv qhov kev xeem online ceev thiab muaj qee tus neeg muaj pub dawb.
Tej zaum yuav muaj ib qho tshwj xeeb rau koj tus kws kho mob hauv internet yog tias koj siv ib lub tuam txhab loj. Ib qho tsis-ISP xyuas seb yog speedof.me. Nws yooj yim heev rau siv thiab yuav muab koj cov qhab-nees ncaj ncees rau ib feeb los yog li ntawd.
Yog tias koj pom tias koj qhov kev twb kev txuas tuaj yeem qeeb los yog tias nws tsis kuaj rau cov qauv koj qhov kev pab yuav tsum tau muab, hu rau lub tuam txhab thiab sib tham txog qhov no nrog lawv. Ntawm chav kawm, peb yuav tsum nco ntsoov tias peb cov cuab yeej ua tau zoo ib yam nkaus thiab. Ib lub tshuab qeeb qeeb wireless lossis lub computer tuaj yeem cuam tshuam koj kev twb kev txuas hauv internet.
