1 Mbps - hais tias hom kev ceev? Luv luv txog khoom thiab bytes

Cov ntsiab lus uas denoting ceev ntawm lub Internet, nws yog ib qho nyuaj to taub ib tug txiv neej uas yog deb ntawm qhov kev kawm. Piv txwv li, cov kev pab cuam muab kev pab muaj Internet ntawm speeds ntawm 1 Mbit / s, tab sis koj tsis paub ib tug ntau los yog ib tug me ntsis. Wb to taub tias qhov no - Mbps, thiab raws li feem ntau ntsuas los ntawm cov kev ceev ntawm koj Internet kev twb kev txuas.

deciphering abbreviations

Lub literal translation ntawm "Mbps" (mbit ib ob) - megabits ib ob. Nws yog nyob rau hauv cov chav nyob feem ntau ntsuas kev twb kev txuas ceev. Tag nrho cov chaw muab kev pab ceev qhia nyob rau hauv lawv cov xwm nyob rau hauv megabits ib ob, thiab nws raug nqi rau peb kom peb nrog cov tseem ceeb.

Ntau npaum li cas nws - 1 Mbps?

Rau ib tug pib, 1 ntsis yog qhov tsawg tshaj plaws tsev ntsuas lub ntim ntawm cov ntaub ntawv. Nyob rau ib tug par nrog tus khiav nrawm, cov neeg feem ntau siv bytes, oblivious mus rau lub fact tias cov ob lub tswv yim yog heev txawv. Tej zaum lawv hais tias, "byte", xa mus rau "me me", thiab vice versa. Yog li ntawd nws yog tsim nyog los xav txog qhov no qhov teeb meem nyob rau hauv ntau yam.

Yog li, lub 1-ntsis - qhov tsawg tshaj plaws chav tsev ntawm kev ntsuas. 8 khoom sib npaug li ib byte, 16-ntsis - .. Ob bytes, thiab lwm yam Nyob rau hauv lwm yam lus, koj cia li yuav tsum nco ntsoov hais tias tus byte yog ib txwm 8 lub sij hawm ntau me me.

Muab hais tias ob qho tag nrho cov chav nyob yog heev me me rau lawv nyob rau hauv feem ntau qhov kev siv ntawm cov prefix "mega", "phaus" thiab "giga". Yuav ua li cas cov tsiaj ntawv ua pib txhais li cas, koj yuav tsum tau paub txog lub tsev kawm ntawv cov kev kawm. Tiam sis yog tias koj tsis nco qab nws, nws yog tsim nyog recalling:

1. "Kilo" - npaug los ntawm 1 000 1 kilobit yog 1000 khoom, 1 kilobyte yog 1024 bytes.
2. "Mega" - npaug by-1 000 000. 1 megabit yog 1000 kilobits (los yog 1,000,000 khoom), 1 megabyte yog 1024 kilobytes.
3. "Giga" - npaug ib 1 000 000 000 1 gigabit yog 1000 megabits (los yog 1 billion khoom), 1 gigabyte yog 1024 megabytes.

Nyob rau hauv cov lus yooj yim, cov kev twb kev txuas ceev - nws yog xa thiab cov kev ceev ntawm cov ntaub ntawv tau txais computer nyob rau hauv ib tug tsev ntawm lub sij hawm (thib ob). Yog hais tias koj qhia kom meej cov kev ceev ntawm koj hauv internet kev twb kev txuas 1 Mbps, cas nws txhais li cas? Nyob rau hauv cov ntaub ntawv no, nws hais tias koj Internet ceev yog 1 megabit ib ob los yog 1000 kbits / ob.

Yog nws yog ib tug ntau

Muaj ntau cov neeg siv ntseeg tias Mbps - uas yog ib tug ntau. Nyob rau hauv qhov tseeb nws tsis yog. Niaj hnub no tus tes hauj lwm thiaj li paub hais tias nrog lawv muaj peev xwm, 1 Mbps - uas yog tsis muaj dab tsi tag nrho. Ntawm no yog muab xam rau ntawm no ceev rau cov piv txwv ntawm daus cov ntaub ntawv los ntawm hauv Internet.

Xav txog hais tias Mbps - nws megabits ib ob. Faib qhov muaj nqis ntawm 1 mus rau 8 thiab tau megabytes. Tag nrho cov 1/8 = 0.125 megabyte / ob. Yog hais tias peb xav mus download tau suab paj nruag los ntawm cov Internet, ces nyob rau hauv lub mob hais tias ib tug khiav, "nyhav" 3 megabytes (feem ntau yog lem npaum li ntawd thiab "luj"), peb yuav tsum tau mus download tau nws nyob rau hauv 24 vib nas this. Xam yooj yim: 3 mebagayta (luj ntawm ib tug khiav) yuav tsum tau muab faib mus rau hauv 0,125 megabyte / ob (Peb ceev). Tshwm - 24 vib nas this.

Tab sis qhov no tsuas yog siv rau hauv lub niaj zaus zaj nkauj. Thiab yog hais tias koj xav mus download tau ib tug yeeb yam, loj 1.5 GB? Cia peb xav txog:

• 1500 (megabytes): 0,125 (megabytes ib ob) = 12 000 (vib nas this).

Txhais vib nas this nyob rau hauv feeb:

• 12 000: 60 = 200 feeb los yog 3,33 lub sij hawm.

Yog li, ntawm 1 Mbps internet ceev, peb yuav tau mus download tau ib tug yeeb yam, ntawm 1.5 Gb ib 3,33 lub sij hawm. Ntawm no tus kws txiav txim rau koj tus kheej, rau ib ntev lub sij hawm los yog tsis.

Muab qhov tseeb hais tias nyob rau hauv loj lub zos ISPs muaj Internet speeds txog li 100 Mbps, peb yuav tau mus download tau lub yeeb yam nrog rau cov tib volume raws li me ntsis li 2 feeb, es tsis txhob ntawm 200. Uas yog 100 lub sij hawm sai. Yog hais tias koj pib los ntawm no, nws muaj peev xwm yuav xaus lus tias Mbps - yog ib tug uas tsis muaj kev ceev.

Txawm li cas los, txhua yam yog tus txheeb ze. Nyob rau hauv ib co thaj chaw deb zos, nyob qhov twg muaj tsis yooj yim mus rau catch txawm lub GSM-network, muaj Internet thiaj ceev ceev - nws yog txias. Txawm li cas los, nyob rau hauv ib tug loj metropolis nrog ib tug lossis loj kev sib tw ntawm qhov kev pab zov me nyuam thiab mobile tswv xws pluag Internet kev twb kev txuas tsis tau.

xaus

Tam sim no uas koj paub yuav ua li cas los mus txiav txim cov kev ceev ntawm lub Internet, thiab muaj peev xwm to taub ib tug me ntsis ntawm cov ntaub ntawv rau lwm. Ntawm cov hoob kawm, yuav tau ploj hauv lawv - ib daim ntawm khoom qab zib, tab sis lub tseem ceeb tshaj plaws yuav tsum nco ntsoov yog hais tias ib tug me ntsis - nws yog ib qho yim ntawm ib tug byte. Ib tug prefix "kilo," "mega" thiab "giga" tsuas ntxiv peb, rau los yog cuaj zeros, ntsig txog. Yog hais tias qhov no yog to taub, ces txhua yam poob rau hauv qhov chaw.
