Cov ntaub ntawv cia nruab nrab nyob rau hauv lub computer kos duab

Ib tug ntawm cov tseem ceeb tshaj plaws teeb meem kev nyuaj siab los ntawm txhua txhua computer tswv, cov nram qab no: "Yuav ua li cas npaj kev ruaj ntseg cia ntawm cov ntaub ntawv." Txawm tias niaj hnub xov xwm nyob rau hauv ib tug ntau yam, feem ntau cov nqi ntawm ntau yam ntawm lawv yog siab dhau heev lawm rau cov lag luam thiab cov tsev neeg siv. Txawm li cas los, muaj ib cov tshuaj. Nws yog tsim nyog mus xyuas li cas yog cov hom ntawm cov xov xwm thiab, muab cov kev xav tau, qhov zoo tshaj plaws kev xaiv nyob rau hauv lub parameter "nqi / nta". Thiab nws yuav tsum coj mus rau hauv tus account lub thiav ntawm cov ntaub ntawv kev ncaj ncees.

Peb pib nrog ib tug txhais. A teev nrab nyob rau hauv computer technology - yog ib yam twj paj nruas uas muaj lub peev xwm los yog lwm txoj kev uas yuav khaws cov kis thereto kho hluav taws xob oscillations thiab kuj muab tau re-nyeem (playback) nyob rau hauv nws thawj daim ntawv. Cov yam ntxwv tseem ceeb raws li nram no:

- tau (los yog impossibility) ntawm re-cov ntaubntawv povthawj siv;

- siv tus cai hais txog kev txuag cov ntaub ntawv;

- ntxwv sib txawv thiab tag nrho cov nqi.

Cov feem ntau cia nruab nrab nyob rau hauv computers - yog lub hard drive (hard drive, HDD). Nws siv ua rau nws tau los mus tsim ib tug high-ceev cov ntaub ntawv cia thiab kev nkag tau mus rau lawv.

Hauv lub lub hlau tsev nyob yog ob peb yam ntawm ib tug kub ceev iav los yog yas disks coated nrog ib tug sib nqus txheej. Thaum tshwj xeeb cov ntaubntawv povthawj siv taub hau nyob rau hauv ib txoj kev yog magnetized nto thiab daig thaum nyeem ntawv cov kev hloov ntawm lub magnetic teb thiab hloov lawv mus rau hauv hluav taws xob Pib ntsais koj teeb, nyob rau hauv qhov tseeb, uas tau txais cov khoom - cov ntaub ntawv. Tam sim no, cov ntaub ntawv no cab kuj yog kev koom nrog raws li manufacturers nce muaj kev xaiv rau ib qho nyuaj drives nrog ib yam nkaus hauv paus ntsiab lus ntawm cia - raws li nyob rau hauv flash nco. Nyob rau hauv lub loj ua lag luam ya ntawm lub interface txuas cov pab kiag li lawm rau koj lub computer - Serial ATA thiab USB. Pab HDD - nws yog ib tug uas tsis muaj nqi ib gigabyte, siab ntseeg thiab kev ua tau zoo, versatility.

Cov nram qab no cia xov xwm - yog ib tug optical disc. cov ntaubntawv povthawj siv txoj ntsiab cai no raws li nyob rau hauv cov creation ntawm ua si nraum zoov laser beam nyob rau hauv cov kabmob hlau txheej, nyob rau hauv txheej sab ntawm uas yog paab coated (substrate). Thaum pab neeg no nyeem beam yog positioned ntawm cov kev kawm khiav (lem), thaws rov los los ntawm tus substrate, teem los ntawm ib tug lens thiab sau cia los ntawm photocell. Txij li thaum cov kev siv ntawm tus txheej txheem nyob rau hauv lub xeev ntawm tus nto, nws ua hluav taws xob me me, uas yog, mus nyeem cov ntaub ntawv kaw tseg.

Nyob ntawm seb cov yam ntxwv ntawm lub beam, muaj ntau yam ntawm CDs thiab nyeem ntawv pab kiag li lawm (drives) lawv: CD nrog 740 MB ntawm muaj volume, DVD nrog 4.7 GB thiab Blu-txoj sab ci nrog 25 GB los yog ntau tshaj. High-zoo disc nrog ceev faj tuav yuav cia cov ntaub ntawv rau ob peb xyoo lawm, txij thaum nws yog tsis raug magnetic teb. Yog xav paub ntxiv cov ntsiab lus nyeem txog CD technology yuav ua tau nyob rau hauv Internet.

Ib qho ntawm feem pheej qhia nyob rau hauv lub teb ntawm xov xwm - nws yog flash nco technology. Nto moo flash nyob rau hauv cov xov tooj txawb - qhov no yog qhov qub heev ntaus ntawv. Rau computers siv lwm yam sab nraud interfaces - USB thiab SATA. Hard drives nrog ib tug khoom-xeev nco yog hu ua. Cov kev siv yog heev yooj yim: nyob rau hauv tag nrho xws li pab kiag li lawm ntsia flash nco nti uas nws hlwb, tsis zoo li cov pa nco modules, muaj peev xwm mus tuav nws raws li txoj cai unchanged kom txog rau thaum 10 xyoo. Thaum lub zog noj yog negligible, vim muaj cov tsis muaj feem mus, thiab siab tshaj plaws kev ntseeg. Cov cuab yeej no yog lossi tau zoo tuaj.

Tseem muaj backup ntaus ntawv raws li nyob rau hauv ib tug sib nqus daim kab xev (lub hauv paus ntsiab lus ntawm cov lag luam yog zoo li tus qub cassettes). Peev Xwm mus 3TB.
