Tsis muaj qhov tsis ntseeg, ib qho ntawm cov lus nug uas muaj feem cuam tshuam txog thev naus laus zis peb tau nug txog ib puag ncig cov ntaub ntawv khaws cia ntsuas, xws li terabytes, gigabytes, petabytes, megabytes, thiab lwm yam.
Tej zaum koj tau hnov feem ntau ntawm cov lus ua ntej, tab sis koj puas paub tias lawv txhais li cas? Muaj pes tsawg gigabytes nyob hauv ib terabyte? Ib terabyte txhais li cas hauv lub ntiaj teb tiag? Cov no yog txhua yam koj yuav tsum paub ua ntej koj yuav lub hard drive lossis daim npav nco, xaiv lub ntsiav tshuaj raws li lub cim xeeb nws muaj, thiab lwm yam.
Zoo hmoo, raws li qhov tsis meej pem raws li txhua yam yuav zoo li thaum xub thawj siab ib muag, tag nrho cov kev ntsuas no tau yooj yim hloov ntawm ib qho mus rau lwm qhov thiab yog cov ntsiab lus yooj yim kom nkag siab ua tsaug rau cov piv txwv peb tau muab hauv qab no.
Cia peb pib nrog qhov pib.
Terabytes, Gigabytes, thiab Petabytes: Uas Loj dua?
Tam sim no, paub qhov twg loj dua thiab qhov twg me dua, nrog rau cov ntawv luv uas sawv cev rau cov lej no, tej zaum qhov txiaj ntsig zoo tshaj plaws kom poob qis.
Tag nrho cov khoos phis tawj thev naus laus zis no ntawm kev ntsuas ntsuas yog nyob ntawm byte, uas yog tus nqi khaws cia yuav tsum khaws ib tus cim ntawm cov ntawv nyeem:
- An exabyte (EB) loj dua ib…
- petabyte (PB), uas loj dua ib…
- terabyte (TB), uas loj dua ib…
- gigabyte (GB), uas loj dua ib…
- megabyte (MB), uas loj dua ib…
- kilobyte (KB), uas loj dua ib…
- byte (B)
Kev pab tsawg hauv lub ntiaj teb tiag yog qhov me me bit (muaj 8 ntsis hauv 1 byte) thiab qhov loj zettabyte thiab yottabyte, ntawm lwm tus. Peb yuav tsis ua raws li daim npav nco yottabyte hauv peb lub koob yees duab txhua lub sijhawm sai sai, yog li xav txog qee cov lus zoo siab los muab pov rau ntawm koj tog tom ntej.
Bytes yog chav ntsuas ntsuas ib txwm siv thaum piav qhia lub peev xwm khaws cia, tab sis kuj tseem muaj qhov me me uas ntau tus neeg muab kev pabcuam hauv internet (ISPs) siv los piav qhia cov ntaub ntawv ceev npaum li cas tuaj yeem rub tawm lossis rub tawm. Nws yog ib qho tseem ceeb kom nkag siab qhov sib txawv ntawm cov khoom thiab bytes kom tsis txhob muaj kev ntxhov siab.
Hloov los ntawm ib chav mus rau lwm qhov, tsuas yog paub tias txhua qib koj nce mus, koj muab 1, 024. Tsis txhob txhawj yog tias qhov tsis meej pem-koj yuav pom cov piv txwv txaus hauv qab no uas koj yuav muaj. lej lej tsis muaj sijhawm. Lub rooj nyob hauv qab ntawm kab lus no pab tau, thiab.
Koj yuav pom ntau qhov chaw hauv online hais tias txhua qib tshiab yog 1,000 npaug ntau dua qhov me dua, tsis yog 1, 024. Txawm tias muaj tseeb hauv qee qhov xwm txheej, hauv cov ntsiab lus siv tau, xav txog seb lub khoos phis tawj siv cov cuab yeej cia, 1, 024 yog qhov tseeb ntau tus lej ua koj cov lej nrog.
Tam sim no mus rau cov khoom siv tau zoo tshaj plaws…
Ntau npaum li cas Gigabytes (GB) hauv ib Terabyte (TB)?
Muaj 1,024 GB hauv 1 TB.
1 TB=1, 024 GB=1, 048, 576 MB=1, 073, 741, 824 KB=1, 099, 511, 627, 776 B
Cia lwm txoj kev…
A TB yog 1,024 npaug loj dua GB. Txhawm rau hloov TB rau GB, tsuas yog muab tus lej TB thiab muab faib los ntawm 1, 024 kom tau txais tus lej GBs. Txhawm rau hloov GB rau TB, tsuas yog muab tus lej GB thiab faib los ntawm 1, 024.
Ntau npaum li cas Megabytes (MB) hauv ib Gigabyte (GB)?
Muaj 1,024 MB hauv 1 GB.
1 GB=1, 024 MB=1, 048, 576 KB=1, 073, 741, 824 B
Zoo li hauv qhov piv txwv dhau los, GB yog 1,024 npaug loj dua li MB. Txhawm rau hloov GB rau MB, coj tus lej GB thiab muab faib los ntawm 1, 024 kom tau txais cov lej ntawm MBs. Txhawm rau hloov MB rau GB, muab tus lej MB thiab faib los ntawm 1, 024.
Megabytes thiab megabits yog qhov sib txawv ntawm kev ntsuas.
Loj npaum li cas Terabyte?
The terabyte (TB) yog chav tsev feem ntau siv los ntsuas qhov loj ntawm lub hard drive thiab tus lej koj tuaj yeem khiav mus rau qee lub sijhawm.
Ib tus kab mob TB muaj ntau qhov chaw. Nws yuav siv 728, 177 floppy disks lossis 1, 498 CD-ROM discs khaws cia 1 TB tus nqi ntawm cov ntaub ntawv.
- Raws li xyoo 2020, feem ntau tshiab, tus nqi nruab nrab ntawm lub computer hard drives nyob hauv 1 txog 5 TB ntau.
- Ntau ISPs cap cov ntaub ntawv ib hlis twg ntawm 1 TB.
- Lub Hubble Space Telescope tsim txog 10 TB ntawm cov ntaub ntawv tshiab txhua xyoo.
- Around 130,000 cov duab digital yuav xav tau 1 TB ntawm qhov chaw… ze li 400 daim duab txhua hnub rau ib xyoos!
- IBM lub npe nrov Watson game-playing supercomputer muaj 16 TB ntawm RAM.
Raws li koj pom hauv GB rau TB lej saum toj no, 1 TB sib npaug me ntsis ntau tshaj ib trillion bytes.
Petabyte Loj npaum li cas?
Lub petabyte (PB) tsuas yog qhov vwm loj ntawm cov ntaub ntawv tab sis nws tau tshwm sim ntau dua hnub no.
Kev khaws cia ib leeg PB yuav siv 745 lab floppy disks lossis 1.5 lab CD-ROM discs, kom meej tsis yog txoj hauv kev zoo khaws cov ntaub ntawv petabyte, tab sis nws lom zem xav txog!
- movie Avatar xav tau kwv 1 PB ntawm kev cia txhawm rau ua cov duab.
- Nws kwv yees tias tib neeg lub hlwb tuaj yeem khaws cia ib puag ncig 2.5 PB ntawm cov ntaub ntawv nco.
- Tshaj 3.4 xyoo 24/7 Full HD video recording yuav nyob ib ncig ntawm 1 PB loj.
- Raws li lig 2018, lub Wayback Machine yog khaws cia tshaj 25 PB ntawm cov ntaub ntawv!
- 1 PB sib npaug rau tshaj 4,000 daim duab digital ib hnub, dhau koj lub neej.
Ib tus PB ib leeg yog 1,024 TB…koj paub, tus lej ntawd peb twb tau tsim muaj ntau heev txawm tias ib leeg! Hauv qhov kev pom zoo dua, 1 PB yog sib npaug rau over 1 quadrillion bytes!
Tus Exabyte Loj npaum li cas?
Hais txog txawm tias ib leeg EB zoo li vwm me ntsis tab sis muaj cov xwm txheej uas lub ntiaj teb yeej khiav mus rau qib ntawm cov ntaub ntawv no.
Yog, nws yog qhov tsis txaus ntseeg, tab sis rov qab mus rau qhov kev sib piv yav dhau los: kom tau mus rau ib qho EB tsuas yog yuav siv 763 billion floppy disks lossis 1.5 billion CD -ROM discs. Koj puas xav txog?
Qee lub siab-bending xav nyob ib ncig ntawm exabytes:
- Rov qab rau xyoo 2010, internet twb tau tuav 21 EB ib hlis, thiab ze li 6 npaug ntawm tus nqi (122 EB) tsuas yog xya xyoo tom qab.
- Yuav luag 11 lab cov yeeb yaj kiab hauv 4K hom yuav haum rau hauv 1 EB cia khoom.
- Ib tus EB tuaj yeem tuav tag nrho Lub Tsev Qiv Ntawv ntawm Congress 3,000 zaug dhau.
- Ib gram ntawm DNA tuaj yeem tuav 490 EB, tsawg kawg hauv kev xav. Qhov ntawd yog tshaj 5 billion 4K tsos. Cia qhov ntawd tso rau hauv ib feeb.
- Cov neeg siv thaub qab lawv cov ntaub ntawv mus rau Backblaze online backup kev pabcuam khaws cia ua ke 1 EB ntawm cov ntaub ntawv ntawm ntau dua 100, 000 hard drives txij thaum ntxov 2020.
Tam sim no rau lej: ib qho EB tuav 1, 024 PB lossis 1, 048, 576 TB. Uas dhau 1 quintillion bytes! Peb yuav tsum saib quintillion - yog, nws yog tus lej!
Loj npaum li cas Gigabyte?
Hais txog GB yog qhov chaw me ntsis-peb pom GBs txhua qhov chaw, los ntawm daim npav nco mus rau rub tawm yeeb yaj kiab, cov phiaj xwm xov tooj smartphone, thiab ntau dua.
Ib ib GB yog sib npaug rau me ntsis dhau 700 floppy disks lossis cia li dhau ib CD.
A GB tsis yog tus lej me me los ntawm txhua txoj kev, tab sis hnub no nws yog qib ntawm cov ntaub ntawv peb siv sai, qee zaum ob peb zaug hauv ib hnub. Nws yog tus lej uas peb tau khiav tawm tsis tu ncua.
- 1 GB khaws tau yuav luag 300 zaj nkauj hauv MP3 hom.
- Ib zaj yeeb yaj kiab HD Netflix yuav gobble tshaj 4 GB raws li koj saib. A 4K version yuav khiav dhau 20 GB!
- A DVD movie disc tuav txog 9.4 GB.
- Ntau lub xov tooj smartphones khw 64 GB lossis 128 GB ntawm cov ntaub ntawv (koj cov apps, suab paj nruag downloads, thiab lwm yam).
- Koj cov ntaub ntawv xov tooj smartphone, uas koj siv thaum koj nyob deb ntawm koj lub wireless network hauv tsev, tej zaum yuav raug capped ntawm 5 GB, 10 GB, lossis me ntsis ntxiv ib hli.
Zoo li peb tau pom hauv MB rau GB hloov dua siab tshiab ob peb ntu saum toj no, 1 GB yog tib yam li tshaj ib txhiab bytes. Qhov ntawd tsis muaj tus lej tsawg, tab sis nws tsis yog ze li ntawm qhov txiaj ntsig zoo li nws ib zaug.
The Byte Table
Ntawm no yog ua ke, uas pab qhia qhov loj npaum li cas ntawm cov lej loj tau!
| Byte Comparison Table | ||
|---|---|---|
| Metric | Vim | Bytes |
| Byte (B) | 1 | 1 |
| Kilobyte (KB) | 1,0241 | 1,024 |
| Megabyte (MB) | 1,0242 | 1, 048, 576 |
| Gigabyte (GB) | 1,0243 | 1, 073, 741, 824 |
| Terabyte (TB) | 1,0244 | 1, 099, 511, 627, 776 |
