Txhua yam koj yuav tsum paub txog bandwidth thiab yuav suav qhov koj xav tau
Lub sij hawm bandwidth muaj ib tug xov tooj ntawm cov ntsiab lus kev tab sis txij li qhov nrov ntawm internet, nws tau feem ntau xa mus rau qhov ntim ntawm cov ntaub ntawv ib ntu ntawm lub sij hawm uas muaj kev sib kis xov nruab nrab (zoo li kev sib txuas hauv internet).
Ib qho kev txuas hauv internet nrog ib qhov loj dua bandwidth txav tau cov nqi ntawm cov ntaub ntawv (hais, video video) sai dua qhov kev twb kev txuas hauv internet nrog qis dua bandwidth.
Bandwidth yog feem ntau hais hauv cov khoom ob , ib yam li 60 Mbps lossis 60 Mb / s, los piav ib cov ntaub ntawv xa mus rau 60 lab khoom (megabits) txhua ob.
Koj Muaj Bandwidth Npaum Li Cas? (& amp; Koj Yuav Tau Npaum Li Cas?)
Saib Xyuas Kev Tshawb Xyuas Koj Lub Ceev Tshaj Lawm rau kev pab li cas los xyuas seb qhov bandwidth koj muaj rau koj npaum li cas. Kev sib tw hauv Internet ceev feem ntau, tab sis tsis tas li, qhov zoo tshaj los ua qhov ntawd.
Koj xav tau ntau npaum li cas rau ntawm qhov koj npaj rau kev ua haujlwm nrog koj qhov kev twb kev txuas hauv internet. Rau qhov feem ntau, ntau dua yog qhov zoo dua, txwv tsis pub ua, ntawm koj cov nyiaj.
Feem ntau, yog tias koj npaj rau kev ua haujlwm tsis muaj dab tsi tabsis Facebook thiab cov yeeb yaj kiab saib yeeb yaj kiab, ib qho kev npaj siab tsawg-ceev yog zaum zoo xwb.
Yog hais tias koj muaj ob peb lub TV uas yuav streaming Netflix, thiab ntau tshaj li ob peb lub tshuab thiab cov khoom siv uas yuav ua rau leej twg-paub-dab tsi, Kuv yuav mus nrog ntau li ntau tau koj them taus. Koj yuav tsis thov txim.
Bandwidth Yog Ib Tug Zoo Li Plumbing
Plumbing muab ib tug zoo analogy rau bandwidth ... tiag!
Cov ntaub ntawv yog kom muaj kev siv bandwidth li dej yog rau qhov loj ntawm lub yeeb nkab.
Hauv lwm cov lus, raws li cov qhab-nees nce siab ua rau tus nqi ntawm cov ntaub ntawv uas muaj peev xwm khiav los ntawm ib lub sij hawm muab, ib yam li ntawm txoj kab nruab nrab ntawm cov yeeb nkab nce, yog li tus nqi dej uas tau los ntawm lub sijhawm .
Hais rau koj tias koj yog tus yeeb yaj kiab, lwm tus neeg ua si hauv online multiplayer video ua si, thiab ob peb lwm tus nyob hauv koj tib lub network yog downloading ntaub ntawv lossis siv lawv cov xov tooj los saib cov yeeb yaj duab online. Nws muaj peev xwm hais tias txhua tus neeg yuav xav tias tej yam me ntsis poob siab yog tias tsis tas li pib thiab siv ceev xwmphem. Qhov no tau ua nrog bandwidth.
Rov qab xa mus rau cov kav dej, piv txwv tias yog cov dej xa mus rau ib lub tsev (qhov bandwidth) tseem yog qhov qub, raws li hauv tsev cov kais dej thiab cov hnyiab tau muab rau (cov ntaub ntawv luam tawm rau cov khoom siv), cov dej nyob ntawm txhua qhov pom tias "ceev" ntawm txhua tus ntaus ntawv) yuav txo tau-dua, vim tias tsuas muaj dej ntau heev (bandwidth) rau hauv tsev (koj qhov network).
Muab lwm txoj kev: bandwidth yog ib qho nyiaj npaum li cas raws li koj them rau. Thaum ib tus neeg yuav ua tau kwj siab video tsis muaj qhov lag luam twg los xij, lub sij hawm koj pib muab lwm cov kev thov download rau lub network, txhua tus yuav tau txais lawv cov peev txheej xwb.
Piv txwv, yog hais tias qhov kev xeem ceev ceev qhia kuv qhov ceev li 7.85 Mbps, nws txhais tau hais tias tsis muaj kev cuam tshuam los sis lwm cov kev siv bandwidth-hogging, Kuv yuav download tau ib daim ntawv ua 7.85 megabit (los yog 0.98 megabytes) hauv ib ob. Ib tug lej me ntsis yuav qhia rau koj tias ntawm qhov tso cai bandwidth, Kuv yuav download tau txog 60 MB ntawm cov ntaub ntawv hauv ib feeb, los yog 3,528 MB hauv ib teev, uas yog sib npaug ntawm ib daim ntawv 3.5 GB ... zoo nkauj ze rau ib qhov ntev, DVD zoo tshaj movie.
Yog li thaum kuv yuav theoretically download tau ib 3.5 GB video ntaub ntawv hauv ib teev, yog tias lwm tus neeg ntawm kuv lub network nws sim mus download tau cov ntaub ntawv zoo sib xws tib lub sij hawm, nws yuav tam sim no siv ob teev kom tiav qhov download vim hais tias dua, network tsuas tso cai x tus nqi ntawm cov ntaub ntawv yuav tsum downloaded rau txhua lub sijhawm, ces nws tam sim no yuav tsum tso cai rau lwm download mus siv ib co ntawm cov bandwidth, ib yam nkaus thiab.
Technically, lub network yuav tam sim no pom 3.5 GB + 3.5 GB, rau 7 GB ntawm tag nrho cov ntaub ntawv uas yuav tsum tau downloaded. Lub peev xwm ntawm kev hloov ntawm bandwidth tsis hloov vim tias qhov theem koj them koj ISP rau, yog li ntawd tib lub tswvyim siv-a 7.85 Mbps network mus rau tam sim no siv ob teev mus download tau 7 GB cov ntaub ntawv cia li zoo li nws yuav siv sij hawm ib teev mus download tau ib nrab ntawm tus nqi.
Qhov txawv hauv Mbps thiab MBps
Nws yog ib qho tseem ceeb kom to taub tias bandwidth tuaj yeem hais tawm hauv ib chav tsev twg (bytes, kilobytes, megabytes, gigabits, thiab lwm yam). Koj ISP yuav siv ib lub sij hawm, ib qho kev ntsuam xyuas lwm tus, thiab ib qho video streaming kev pab cuam tsis tau. Koj yuav tsum to taub tias cov ntsiab lus no muaj txhij txhua li cas thiab yuav hloov li cas ntawm lawv yog tias koj xav kom tsis txhob them nqi rau cov kev pab cuam ntau dhau hauv internet los yog, tej zaum yuav mob ntxiv, kom tsis txaus rau yam koj xav ua nrog nws.
Piv txwv, 15 MBs tsis zoo tib yam li 15 Mbs (faj seeb ntxiv rau b). Tus thawj nyeem ua 15 megaBYTES thaum ob yog 15 megaBITS. Qhov ob qhov tseem ceeb yog txawv ntawm ib qhov tseem ceeb ntawm 8 vim tias muaj 8 khoom hauv ib qho kev byte.
Yog hais tias cov kev nyeem ob feem ntawm bandwidth tau sau hauv megabytes (MB), lawv yuav yog 15 MB thiab 1.875 MB (txij li 15/8 yog 1.875). Txawm li cas los xij, thaum sau ntawv hauv megabits (Mb), thawj zaug yuav yog 120 Mbs (15 x 8 yog 120) thiab qhov thib 15 Mbps.
Tswv yim: Lub tswvyim qub no siv rau cov ntaub ntawv uas koj tuaj yeem ntsib. Koj tuaj yeem siv lub laij tawm tswv yim online sib tw zoo li qhov no yog tias koj tsis xav ua lej li cas. Saib Mb vs MB thiab Terabytes, Gigabytes, & Petabytes: Lawv loj npaum li cas? yog xav paub ntxiv.
Xav paub ntxiv txog Bandwidth
Qee software cia koj txo tus nqi bandwidth uas qhov kev tso cai tau txais kev siv, uas yog qhov yuav pab tau tiag tiag yog koj tseem xav kom qhov kev zov me nyuam ua haujlwm tab sis nws tsis tas yuav tsum khiav ntawm ib qho kev ceev. Qhov kev txwv no feem ntau yog hu ua bandwidth control .
Muaj qee cov thawj tswj kev lag luam , xws li Tus Tiv Thaiv Free Download, piv txwv, txhawb kev tswj hwm kev sib txuas lus, ua ntau yam kev pabcuam hauv online , qee cov kev pabcuam huab, cov kev pabcuam torrent , thiab qee qhov chaw khiav haujlwm . Cov no yog tag nrho cov kev pabcuam thiab cov kev pab cuam uas yuav kam nrog loj npaum li cas ntawm bandwidth, yog li nws ua rau kev nkag siab muaj cov kev xaiv uas txwv lawv txoj kev nkag.
Raws li tus piv txwv, hais tias koj xav mus download tau ib daim ntawv loj loj 10 GB. Tsis txhob siv sij hawm rau lub sij hawm, tshem tawm txhua qhov muaj bandwidth, koj yuav siv ib tus thawj tswj download tau thiab qhia cov kev pab cuam kom tsis txhob mus rub kom siv tsuas yog 10% ntawm qhov muaj bandwidth. Qhov no yuav, ntawm chav kawm, ruaj ntxiv lub sij hawm rau tag nrho cov sij hawm ces nws kuj tseem tuaj yeem tuaj yeem ua haujlwm ntau dua rau lwm lub sij hawm-kev ua si xws li cov yeeb yaj duab hauv video.
Ib yam dab tsi zoo li cov kev tswj bandwidth yog bandwidth throttling . Qhov no kuj yog ib qho kev tswj xyuas kev sib txuas lus uas yog qee zaum tso ntawm cov chaw muab kev pab cuam internet rau qee yam kev txwv qee yam kev tsav tsheb (xws li Netflix streaming lossis cov ntaub ntawv sib faib) los yog txo tag nrho cov tsheb khiav qee lub sij hawm hauv nruab nrab hauv hnub kom thiaj li txo tau kom tsis txhob muaj teeb meem.
Kev ua haujlwm hauv network yog txiav txim tau los ntawm ntau tshaj qhov ntau npaum li cas bandwidth koj muaj. Muaj qee yam tseem ceeb xws li latency , khib nyiab, thiab pob ntawv poob tawm uas tuaj yeem cuam tshuam txog kev ua haujlwm tsawg dua li qhov xav tau hauv txhua lub network.
