Cov ntaub ntawv tus nqi ntawm kev sib txuas network yog ib txwm ntsuas nyob rau hauv units ntawm cov khoom ib ob, feem ntau abbreviated li bps es tsis txhob b / s. Cov cuab yeej siv network cov tuam txhab ntsuas qhov siab tshaj plaws network bandwidth qib lawv cov khoom txhawb nqa siv cov qauv ntsuas ntawm Kbps, Mbps, thiab Gbps.
Cov no yog qee zaum hu ua internet ceev units vim hais tias thaum network ceev nce, nws yooj yim dua los qhia lawv hauv ntau txhiab (kilo-), lab (mega-) lossis billions (giga-) ntawm chav nyob ib zaug.
Definition
Vim kilo- yog txhais tau tias tus nqi ntawm ib txhiab, nws tau siv los qhia qhov qis tshaj plaws ntawm pawg no:
- Ib kilobit ib ob sib npaug 1,000 khoom ib ob. Nov yog qee zaum sau li kbps, Kb/sec lossis Kb/s tab sis txhua tus muaj lub ntsiab lus tib yam.
- Ib megabit ib ob sib npaug 1000 Kbps lossis ib lab bps. Nws kuj tau nthuav tawm raws li Mbps, Mb/sec, thiab Mb/s.
- Ib gigabit ib ob sib npaug 1000 Mbps, ib lab Kbps lossis ib txhiab bps. Nws kuj tseem hu ua Gbps, Gb/sec, thiab Gb/s.
Kev zam kev tsis meej pem ntawm cov khoom thiab bytes
Rau keeb kwm vim li cas, cov ntaub ntawv tus nqi rau disk drives thiab qee yam khoom siv tsis yog hauv lub network yog qee zaum qhia hauv bytes ib thib ob (Bps nrog tus lej B) ntau dua li cov khoom ib ob (bps nrog tus lej 'b').
- ib KBps sib npaug ib kilobyte ib ob
- ib MBps sib npaug ib megabyte ib ob
- ib GBps sib npaug ib gigabyte ib ob
Vim tias ib byte sib npaug yim me ntsis, hloov cov kev ntaus nqi no mus rau tus lej 'b' sib raug zoo tuaj yeem ua tau yooj yim sib npaug los ntawm 8:
- ib KBps sib npaug 8 Kbps
- ib MBps sib npaug 8 Mbps
- ib GBps sib npaug 8 Gbps
Kom tsis txhob muaj kev tsis sib haum xeeb ntawm cov khoom thiab bytes, cov kws tshaj lij kev sib txuas lus ib txwm xa mus rau kev sib txuas hauv network ceev raws li bps (tus lej 'b') kev ntaus nqi.
Kev ntsuas nrawm ntawm cov khoom siv sib txuas sib txuas
Network iav nrog Kbps ceev kev ntsuam xyuas nyiam cov laus dua thiab ua haujlwm qis los ntawm cov qauv niaj hnub. Qub dial-up modems txhawb cov ntaub ntawv tus nqi txog 56 Kbps, piv txwv li.
Ntau cov khoom siv network nta Mbps ceev kev ntsuas.
- Kev sib txuas hauv Is Taws Nem hauv tsev tuaj yeem muaj los ntawm cov nqi qis xws li 1 Mbps txog 100 Mbps thiab siab dua
- 802.11g Wi-Fi kev sib txuas tus nqi ntawm 54 Mbps
- Kev sib txuas Ethernet qub ntawm 100 Mbps
- 802.11n Wi-Fi kev sib txuas tus nqi ntawm 150 Mbps, 300 Mbps, thiab nce siab dua
High-end iav nta Gbps ceev ntsuas:
- Gigabit Ethernet txhawb 1 Gbps
- Backbone network txuas uas pub cov chaw muab internet thiab cov xov tooj ntawm tes txhawb nqa ntau Gbps
Dab tsi Los Tom Qab Gbps?
1000 Gbps sib npaug 1 terabit ib ob (Tbps). Ob peb technologies rau Tbps ceev networking muaj nyob niaj hnub no.
Txoj haujlwm Internet2 tau tsim Tbps kev sib txuas los txhawb nws txoj kev sim network, thiab qee lub tuam txhab kev lag luam kuj tau tsim cov ntawv xeem thiab ua tiav Tbps txuas.
Vim tus nqi siab ntawm cov cuab yeej siv thiab cov kev cov nyom rau kev khiav lag luam xws li lub network ntseeg tau, cia siab tias nws yuav muaj ntau xyoo ua ntej cov qib ceev no ua tau zoo rau kev siv dav.
Yuav ua li cas cov ntaub ntawv tus nqi hloov pauv
Nws yooj yim heev los hloov ntawm cov chav no thaum koj paub tias muaj 8 cov khoom hauv txhua byte thiab kilo, Mega, thiab Giga txhais tau tias txhiab, lab thiab billion. Koj tuaj yeem ua cov lej ntawm koj tus kheej los yog siv ib qho ntawm ntau lub tshuab xam zauv online.
Piv txwv li, koj tuaj yeem hloov Kbps rau Mbps nrog cov cai ntawd. Yog li 15,000 Kbps=15 Mbps vim tias muaj 1,000 kilobits hauv txhua 1 megabit.
CheckYourMath yog lub laij lej txias uas txhawb nqa cov ntaub ntawv hloov pauv yog tias koj xav sim lawv ntawm koj tus kheej.
