Lub ntsiab ntawm cov nqi me ntsis (Kbps, Mbps & Gbps) thiab nws yog tus ceev tshaj plaws
Cov ntaub ntawv ntawm qhov kev sib txuas ntawm network yog feem ntau ntsuas ntawm cov khoom hauv ib qho thib ob (bps). Network khoom manufacturers tus nqi siab tshaj plaws bandwidth theem lawv cov khoom siv txhawb nqa siv cov txheej txheem ntawm Kbps, Mbps, thiab Gbps.
Cov no yog qee zaum hu ua kev sib txuas hauv internet vim hais tias raws li kev nce qib network, nws yooj yim los qhia rau lawv nyob hauv ntau txhiab (kilo), lab tus (mega) lossis billions (giga) ntawm ib zaug.
Cov ntsiab lus
Txij li thaum kilo - yog txhais tau hais tias muaj nqis ib txhiab, nws yog siv los ua kom pom qhov qis qis ntawm pawg neeg no:
- Ib kilobit ib xuab moos (Kbps) sib npaug 1,000 khoom ib pliag (bps). Qhov no qee zaum sau ua kbps, Kb / sec los yog Kb \ / s, tiam sis tag nrho lawv nqa tib lub ntsiab lus.
- Ib tug megabit thib ob (Mbps) sib npaug 1000 kb los yog ib vam bps. Nws tseem qhia tias Mbps, Mb / sec, thiab Mb / s.
- Ib tug gigabit ib ob (Gbps) sib npaug 1000 Mbps, ib vam kb Kbps lossis ib bill bps. Nws kuj yog luv li Gbps, Gb / sec, thiab Gb / s.
Tsis Txhob Cia Siab Tsis Hlwb Ntawm Khoom thiab Bytes
Cov ntaub ntawv keeb kwm, cov ntaub ntawv cov nqi rau cov tsav drives thiab qee cov khoom siv (non-network) muaj qee zaum hauv cov xuabmoos ib zaug (Bps nrog rau ib daim ntawv loj loj B) es tsis txhob ua ob zaug (bps nrog qis qis 'b').
- ib KBps sib npaug ib kilobyte ib pliag
- ib tug MBps sib npaug ntawm ib tus megabyte ib pliag
- ib GBps qhov sib npaug ntawm ib lub gigabyte thib ob
Vim tias ib tug byte sib npaug ntawm yim khoom, hloov cov kev ntsuam xyuas rau cov lus nug sab nraud 'b' coj mus ua ib kab zauv los ntawm 8:
- ib KBps sib npaug li 8 Kbps
- ib MBps sib npaug 8 Mbps
- ib GBps qhov sib npaug 8 Gbps
Yuav kom tsis txhob muaj kev ntxhov siab ntawm cov khoom thiab cov bytes, networking cov tub txawg nco ntsoov xa mus rau kev sib txuas ntawm kev sib txuas ntawm kev sib txuas ntawm bps (lowercase 'b') kev.
Ntaus Nqi ntawm Cov Khoom Siv Network
Network iav nrog Kbps qhov kev sib tw nyhav dhau los ua cov laus thiab cov kev ua tau zoo los ntawm cov qauv siv niaj hnub no. Qub dial-up modems txaus siab txog cov ntaub ntawv txog li 56 Kbps, piv txwv li.
Cov khoom siv feem ntau ntawm cov cuab yeej muaj nuj nqi Mbps.
- Kev sib txuas hauv internet muaj peev xwm ua tau los ntawm qhov tseem ceeb xws li 1 Mbps txog li 100 Mbps thiab txawm siab zog
- 802.11g Wi-nkaus txuas Tus nqi ntawm 54 Mbps
- Cov Kev Sib Txuas Ncig Qub Ethernet Tus Nqi ntawm 100 Mbps
- 802.11n Kev sib txuas ntawm Wi-Fi Tus nqi ntawm 150 Mbps, 300 Mbps, thiab nce siab ntau dua
High-end iav nta Gbps kev ntsuam xyuas:
- Gigabit Ethernet txhawb 1 Gbps
- Nruab nrab network txuas uas pub rau cov neeg zov me nyuam hauv internet thiab xov tooj ntawm tes txhawb ntau Gbps
Dab tsi tuaj tom qab Gbps?
1000 Gbps sib npaug 1 tauj ib zaug (Tbps). Tsawg yees rau Tbps ceev networking nyob niaj hnub no.
Qhov project hauv Internet2 tau tsim Tbps cov kev txuas los pab txhawb nws txoj kev sim, thiab qee lub tuam txhab kev lag luam muaj peev xwm ua kev kuaj mob thiab ua tiav Tbps cov kev sib txuas.
Vim tias tus nqi siab tshaj ntawm cov khoom siv thiab kev cov nyom rau kev khiav hauj lwm xws li lub network nti tawm tau zoo, cia siab tias nws yuav ntau ntau xyoo ua ntej cov kev khiav ceev no ua rau kev siv dav dav.
Yuav ua li cas Ua Cov Ntawv Sib Pauv Cov Ntaub Ntawv
Nws yog qhov yooj yim los hloov ntawm cov koog no thaum koj paub tias muaj 8 daim ntawm txhua tus neeg bytes thiab ntawd kilo, Mega, thiab Giga txhais tau ntau txhiab, lab thiab billion. Koj tuaj yeem ua cov lus teb koj tus kheej manually lossis siv ib lub xov tooj ntawm cov laij zauv hauv internet.
Piv txwv li, koj tuaj yeem hloov Transformers rau Mbps nrog cov cai. 15,000 Kbps = 15 Mbps vim tias muaj 1,000 kilobits hauv txhua 1 megabit.
CheckYourMath yog ib lub laij tawm tswv yim uas txhawb cov nqi ntawv hloov. Koj tuaj yeem siv Google, zoo li qhov no.
