Terabyte: Tauv nqi pes tsawg? Yuav ua li cas muaj ntau yam terabayte 1 gigabyte?

Peb high-tech muaj hnub nyoog yog txawv los ntawm lub yav dhau los sawv daws yuav rau nws ntau yam zoo. Yog hais tias ua ntej lawm ntaub ntawv tau txais tsuas yog los ntawm dab neeg ntawm cov neeg txawj ntse thiab cov tsev qiv ntawv, tam sim no tej lo lus nug, koj yuav tau "zaguglit", thiab nyob rau tib lub sij hawm ntawd tau ib tug authoritative teb. Cov ntaub ntawv uas yog cia nyob rau hauv lub ntiaj teb no network Internet. Nws heev npaum li cas. Tsis txaus rau ib xyoo pua, mus rov nyeem tag nrho cov tau thiab tej yam uas koj nyiam. Tab sis yuav ua li cas rau cov ntaub ntawv uas yog cia nyob rau hauv cov daim ntawv no? Yuav ua li cas yog qhov tsawg kawg nkaus thiab lub siab tshaj plaws tsev ntawm cov ntaub ntawv? Muaj ntau, tau nws tus kheej ib tug xam ntaus ntawv, feem ntau xav yuav ua li cas muaj ntau yam gigs nyob rau hauv 1 terabayte. Tag nrho cov ntawm no yuav muaj nyob rau hauv no tsab xov xwm.

Yuav ua li cas yog cov ntaub ntawv nyob rau hauv lub computer teb?

Tam sim no heev nrov hluav taws xob computers nrog ib tug cia muaj peev xwm ntawm 1 terabyte. Yuav ua li cas npaum li cas yog nyob rau hauv lub GB los yog MB? Yuav kom to taub li cas cov lus qhia thiab yuav ua li cas hloov nws los ntawm ib tug txiav txim rau lwm tus, ua ntej ntawm tag nrho cov, koj yuav tsum to taub hais tias nyob rau hauv tej xam ib puag ncig, cim yog sawv cev nyob rau hauv binary daim ntawv nyob rau hauv daim ntawv ntawm zeros thiab sawv daws yuav. Khoos phib tawj tshuab muab commands thiab cov ntaub ntawv los ntawm cov tswv yim pab kiag li lawm, yog tau cia, cov txheej txheem thiab txhais cov ntaub ntawv nyob rau hauv li ib txwm daim ntawv rau ntsoos ntsoos mechanism, xws li ib tug saib, screen xov tooj, ntsiav tshuaj, los yog lwm yam kev pab kiag li lawm.

Yuav kom txhais txhua yam ntawm cov ntaub ntawv - ntawv nyeem, graphics, suab los yog yees duab - siv cov ntaub ntawv transformation, hu ua encoding. Yog li ntawd, yuav cov ntaub ntawv los ntawm lub decimal system txhais mus rau hauv binary, thiab vice versa. Cov ntaub ntawv yuav raug suav nyob rau hauv bytes, megabytes, terabytes. Tej zaum koj yuav nug, yuav ua li cas muaj ntau yam gigabytes terabayte. Qhov no yuav tsum tau tham ib tug me ntsis rau yav tom ntej, thaum peb piav qhia txog cov ntaub ntawv hloov lwm lub tsev system.

QAUV hloov ntaub ntawv los ntawm ib tug zauv xov tooj system mus rau ib tug binary kev ntsuas thiab cia lawv

Piv txwv peb muaj tus xov tooj 156 nyob rau hauv decimal cim. Peb yuav tsum txhais nws rau hauv ib cov hom ntawv. Yuav ua li cas yuav ua rau nws manually? Nws yog tsim nyog los faib nws mus rau hauv 2 raws li ntev raws li nws tsis ua tsis yooj yim sua.

1. Thawj txiav txim: 156/2 = 78. Cov seem ntawm lub division yog 0, nws yuav muab lub xeem lej ntawm binary ntaub ntawv ntsuas system, thiab, raws li, nws yog nyob rau hauv ib tug tej yam cim xeeb ntawm cov computer ntaus ntawv thiab muab ua khoom - yam tsawg kawg nkaus ntaub ntawv ntsuas cov kauj ruam.
2. Ntxiv - 78/2 = 39. Cov seem ntawm lub division dua 0. Cov penultimate zauv binary code rov qab mus rau 0. Nws yuav siv sij hawm li heev me ntsis qhov chaw, yog li nws yuav tsum tau suav nyob rau hauv me me. Tab sis los teev ib tug lossis loj npaum li cas ntawm video ntaub ntawv uas yuav tsum tau loj nyiaj ntawm cov computer nco kiag li lawm, xws li terabytes. Yuav ua li cas no me ntsis, koj hais? Thiab peb tuaj mus rau rau lo lus nug.
3. Cov theem tom ntej ntawm kev faib - nthuav ntau. Peb muaj ib tug xov tooj ntawm 39. Nws tsis yog tusyees divisible los ntawm tus xov tooj 2. Yuav ua li cas yuav tsum tau ua li cas? 39/2 = 19. Cov seem ntawm lub division - 1. Qhov no xam yuav tsum yog tus thib peb txij thaum kawg ntawm lub binary code.
4. Tom ntej txiav txim - 19/2 = 9 (los ntawm residue 1). Peb sau qhov nqi koj tshuav ua ntej uas twb muaj lawm peb tug lej tom qab ntawm cov lus teb.
5. 9/2 = 4 nrog ib tug seem 1. Sau lub thib tsib chav tsev los ntawm lub kawg ntawm lub teb binary code.
6. 4/2 = 2 tsis muaj residue. Yog li ntawd, peb append mus rau lub binary code 0.
7. 2/2 = 1. Cov seem ntawm lub division - 0, nkag mus rau nws mus rau hauv lub code, thiab tsis txhob hnov qab mus ntxiv tus so ntawm lub tsev.

Yog li ntawd nws tshwm sim peb txhais ib tug yooj yim decimal rau binary tshuab code, uas lub computer tuam haujlwm txais ib feem ntawm ib tug millisecond, txhais nws rau hauv me me. Tab sis lub prime tooj yuav siv sij hawm li heev me ntsis nco, muab piv nrog graphics los yog cov yeeb yaj duab nyob rau hauv HD zoo. Muaj ntau nug cov lus nug: "1 tus kab mob TB - yuav ua li cas muaj ntau yam gigabytes thiab yuav ua li cas muaj ntau yam ntaub ntawv yuav tsum muab cia rau hauv ib disc nrog no volume?". Muab hais tias ib tug terabyte - ib qho ntawm lub siab tshaj plaws ntsuam ntawm lub ntsuas yog txaus.

Uas twb muaj lawm units ntawm cov ntaub ntawv

Tus me tshaj unit ntawm ntsuas qhov ntim ntawm cov lus qhia nyob rau hauv ib tug computer yog xav tau lub cheeb tsam ntawm lub ntsis, uas yuav muaj ib tug nqi ntawm 0 los yog 1. Cov tom ntej no byte yog tom qab nws. Nws sib npaug yim me me. Niaj hnub no, flash drives, nco phaib thiab tshem tau xov xwm yuav tsis ua ib tug 1 gigabyte. Tau, thiab nws yog suav tias yog heev me me nyob rau hauv volume. Yog suab tsis yuav computer pab kiag li lawm uas nws nrog nco yog tsawg tshaj li 1 terabyte. Qhov no yog yuav ua li cas muaj ntau yam gigabytes? Nyob rau hauv ib terabayte haum 1024 gigabytes. Ib impressive duab, tsis yog nws? Tab sis qhov no yog tsis yog qhov kev txwv muaj nqis. Nqi siab tshaj plaws kev ntsuas tus nqi ntawm cov ntaub ntawv yog suav tias yog nyob rau lub sij hawm ntawd yottabayt.

Neeg txhais lus ntawm ib tug unit ntawm kev ntsuas mus rau lwm lub

Kom hloov los ntawm ib tug me me chav tsev mus rau ib tug loj npaum li cas ntawm cov ntaub ntawv, thiab vice versa, los ntawm lub siab mus rau lub sab, nws yog tsim nyog los paub qhov yooj yim qhov tseem ceeb thiab lawv txhais lus. Qhov tsawg kawg nkaus tus nqi muaj tsuas yog ob tug cim thiab yog hu ua binary.

Tus tom ntej loj tshaj kev ntsuas ntawm ib tug uas zoo sib xws lub npe - bytes. Nws muaj ib tug muaj peev xwm ntawm 8 me me, thiab, ntsig txog, 16 cim. Tom ntej no, siv cov lub npe hu ua ntej lo lus kilo, mega, giga, tera- lwm yam, uas sib tau cov zauv nyob rau hauv binary cim: 2 ¹⁰ = 10 ² = 10 ^{20 Lub ob hlis ntuj 3} Lub ob hlis ntuj ³⁰ = 10 ^4, 2 ⁴⁰ = ¹⁰ Tej zaum.

Yuav ua li cas muaj ntau yam gigabytes terabayte? Yog hais tias peb xav hais tias cov tera - qhov no xov tooj nyob rau hauv lub binary system ntawm xam ntawm 2 ^{mus rau 40,} thiab giga - Lub ob hlis ntuj ^30, ces qhov txawv yuav nyob rau hauv lub xov tooj ntawm 1024 = ^{10 Lub ob hlis ntuj.}

Qhov saum toj no piav txog txoj kev transforming decimal rau binary. Yog hais tias ib tug neeg yog tsis meej yuav ua li cas muaj ntau yam gigs nyob rau hauv terabayte siv online tswvyim uas yuav txiav xam tej nqi thiab chav tsev ntawm kev ntsuas.

Yuav ua li cas siv online tswvyim los hloov units ntawm kev ntsuas?

Muaj ntau ntau ntawm cov kev pab cuam mus rau cov hloov xov tooj los ntawm ib tug lub tsev ntawm kev ntsuas mus rau lwm lub. Yuav kom hloov tej nqi ntawm cov ntaub ntawv tsim nyog los nrhiav tau cov ntaub converter units. Yog hais tias koj xav mus xam 1 terabyte, raws li nws yog MB, GB, los yog me me, ces sau nyob rau hauv lub dawb paug cell "1", xaiv los ntawm txoj kev nco cia daim ntawv teev cov qhov tseem ceeb ntawm uas koj xav kom hloov (nyob rau hauv cov ntaub ntawv no - tus kab mob TB). Nyob rau hauv lwm nco-down daim ntawv teev - ib tug nyob rau hauv uas koj xav kom hloov. Qhov no yuav ua tau tsis hais cov tsis thiab ib tug loj kom muaj nuj nqis ntawm kev ntsuas cov kauj ruam. Cov lus teb uas koj tau txais tam sim ntawd.

Yuav ua li cas muaj ntau yam tshem tau flash drives yuav hloov 1 hard drive 1 kab mob TB?

Peb tsis thov kom koj ib lo lus nug txog ntau npaum li cas cov lus qhia yuav muaj ib tug hard disk peev xwm ntawm 1 TB? Ntau npaum li cas nws nyem drives nrog ib tug nruab nrab ntawm 32 GB? 1024/32 = 32 stick. Thiab yog hais tias nws yog los lo rau lub 64 gig? Ces 1024/64 = 16 cia kiag li lawm. Kuj muaj ntau, tsis yog nws? Tsis yooj yim mus yuav ib lub computer ntaus ntawv xws loj loj ntau thiab yeej tsis muaj kev txhawj hais tias koj muaj tsis muaj qhov chaw khaws cov duab, cov yeeb yaj duab, tus tsim nyog cov kev pab cuam rau kev ua hauj lwm los yog ua si?

Yuav ua li cas yuav tsum nco ntsoov cov chav nyob ntawm cov ntaub ntawv?

Yuav kom sai sai thiab yooj yim nco ntsoov, 1 terabyte - yuav ua li cas muaj ntau yam gigabytes, yuav tsum tau cia li ib hnub mus nyeem ib qho kev nthuav anecdote txog programmers. Nws suab zoo li no: "Yuav ua li cas distinguishes qhov dog dig txiv neej los ntawm lub programmer? Nws yog xav hais tias nyob rau hauv 1 kg ntawm hnyuv ntxwm 1000 g, thiab xeem nws programmer 1024 g ".
