Megabit vs Megabyte - Ib qho kev piav qhia thiab hloov kev hloov
Megabits (Mb) thiab megabytes (MB) zoo tib yam, thiab lawv cov ntawv sau siv tib lub npe ntawv, tab sis lawv yeej tsis txhais hais tias tib yam nkaus.
Nws yog ib qho tseem ceeb kom paub qhov txawv ntawm ob thaum koj xam xyuas cov khoom zoo li koj txoj kev txuas hauv internet thiab qhov loj ntawm cov ntaub ntawv los yog cov tsav nyuab .
Dab tsi yog nws txhais tau hais tias koj tau kuaj koj cov kev ceev hauv internet thiab koj tau hais tias nws yog 18.20 Mbps? Npaum li cas yog tias hauv MB? Yuav ua li cas hais txog tus tsav flash uas muaj 200 MB lawm - kuv puas nyeem hauv Mb yog kuv xav?
Tus Me & # 34; b & # 34; vs tus loj & # 34; B & # 34;
Megabits yog Mb los yog Mbit thaum sib tham txog cov khoom cia, los yog Mbps (megabits ib ob) raws li cov ntsiab lus ntawm kev hloov ntaub ntawv. Tag nrho cov no yog hais nrog ib tug lowercase "b."
Piv txwv li, kev sib tw hauv internet ceev tuaj yeem ntsuas koj lub network qhov ceev ntawm 18.20 Mbps, uas txhais tau hais tias 18,20 megabits raug xa mus rau txhua ob. Dab tsi yog qhov nthuav yog tias tib qhov kev ntsuas tau hais tias qhov qhoos kas no muaj 2,275 Mb, los yog megabytes ib pliag, thiab qhov tseem ceeb tseem yog sib npaug.
Yog tias cov ntaub ntawv koj downloading yog 750 MB (megabytes), nws yog technically kuj 6000 Mb (megabits).
Ntawm no yog vim li cas, thiab nws yooj yim heev ...
Muaj 8 Cov Khoom Hauv Txhua Tus Neeg Tuaj
Ib qho me ntsis yog ib tug binary digit los yog chav tsev me me ntawm cov ntaub ntawv siv computer. Ib me ntsis yog tiag tiag, me tiag tiag - me dua qhov loj ntawm ib tus neeg ua cim hauv ib qho email. For the sake of simplicity, xav txog me ntsis raws li tib lub me me ntawm cov ntawv nyeem ua cim. Ib tug megabit, tom qab ntawd, yog kwv yees li ntawm 1 lab lub cim hom.
Ntawm no yog qhov uas qhov mis 8 khoom = 1 byte siv tau los hloov ua megabits rau megabytes, thiab vice versa. Lwm txoj kev los saib nws yog hais tias ib tug megabit yog 1/8 ntawm ib tug megabyte, los yog hais tias ib tug megabyte yog 8 lub sij hawm ntawm ib megabit.
Vim peb paub hais tias ib lub megabyte yog 8 npaug li cas qhov megabit muaj nuj nqis, peb tuaj yeem xam qhov megabyte qhov sib npaug los ntawm multiplying tus xov tooj megabit los ntawm 8.
Nov yog qee cov qauv yooj yim:
- Yim (8) megabits = 1 megabyte (8 Mb = 1 MB)
- Ib (1) megabit = 1/8 megabyte = 0.125 megabyte (1Mb = 1/8 MB = 0.125 M)
Ib txoj hauv kev yooj yim kom nco ntsoov qhov sib txawv ntawm qhov megabit thiab ib tug megabyte yog cia li nco ntsoov tias thaum lawv cov khoom sib npaug (yog li thaum koj muab piv Mb nrog Mb, lossis MB nrog MB) megabit (Mb) tus xov tooj yuav tsum yog loj (vim hais tias muaj 8 khoom nyob rau hauv txhua txhua bytes).
Txawm li cas los xij, txoj kev ceev tshaj plaws kom paub txog qhov megabit thiab megabyte hloov dua siab tshiab yog siv Google. Cia li nrhiav ib yam dab tsi zoo li 1000 megabits rau megabytes.
Lus Ceeb Toom: Txawm tias lub megabyte yog 1 lab bay, qhov kev hloov dua siab tshiab tseem "lab ntawm lab" vim hais tias ob qho tag nrho yog "megas," txhais hais tias peb siv 8 raws li qhov hloov dua siab tshiab es tsis muaj 8 lab.
Vim Li Cas Koj Yuav Tsum Paub Qhov Sib Thooj
Paub tias megabytes yog qhov txawv ntawm megabits tseem ceeb heev thaum uas koj nyob nraum soj ntsuam nrog koj kev twb kev txuas hauv internet vim tias feem ntau tsuas yog lub sij hawm koj txawm pom megabits thaum nws tawm mus rau cov khoom siv sib txuas.
Piv txwv li, yog tias koj tau sib piv hauv internet ceev thaum nriav pob ntawv hauv internet los ntawm ib tus neeg muab kev pab cuam , koj yuav nyeem tau tias ServiceA yuav xa 8 Mbps thiab ServiceZ muaj 8 MBpps.
Ntawm kev ceev nrooj, lawv yuav zoo li zoo tib yam thiab koj yuav cia li xaiv qhov twg yog qhov pheej yig tshaj. Txawm li cas los xij, muab qhov kev hloov dua tshiab tau piav los saum no, peb paub tias ServiceZ sib npaug rau 64 Mbps, uas yog yim zaug sai dua li ServiceA:
- ServiceA: 8 Mbps = 1 MB
- ServiceZ: 64 Mbps = 8 MBps
Kev xaiv qhov pheej yig dua yuav txhais tau tias koj yuav tau ServiceA, tab sis yog tias koj xav tau ceev ceev ceev, koj yuav tau xav yuav qhov kim kim. Qhov no yog vim li cas nws thiaj li tseem ceeb kom paub txog qhov lawv txawv.
Ua li cas txog Gigabytes thiab Terabytes?
Cov no yog qee lo lus siv los piav txog cov ntaub ntawv cia, tab sis muaj ntau, ntau dua li ntawm megabytes. Nyob rau hauv qhov tseeb, ib tug megabyte, uas yog 8 lub sij hawm qhov loj ntawm ib tug megabit, yog tiag 1/1000 ntawm ib tug gigabyte ... uas yog me me!
