Internal thiab sab nraud nco cia. Hom nco Drives

Tej hluav taws xob computers xws li nco cia kiag li lawm. Yog tsis muaj lawv, tus neeg teb xov tooj yuav tsis muaj peev xwm cawm lub txiaj ntsim ntawm lawv cov chaw ua hauj lwm, los yog theej rau lwm nruab nrab.

punch phaib

Nyob rau hauv thaum ntxov hnub ntawm computer technology rau cia ntaub ntawv siv punch phaib - zoo tib yam duab los qhia ntawv rau daim ntawv thov ntawm cov cim.

Nyob rau hauv ib punched card muab tso rau 80 txhua, txhua kem ua kom ib tug me ntsis ntawm cov ntaub ntawv. Lub qhov nyob rau hauv cov kab sib haum mus rau ib tug. Cov ntaub ntawv kev nyeem ntawv tshwm sim successively. Re-cov ntaub ntawv dab tsi rau punched card yog tsis yooj yim sua, li ntawd, lawv yuav tsum tau ib tug lossis loj npaum li cas. Cia array 1 GB yuav siv sij hawm 22 tons ntawm daim ntawv.

Ib tug zoo xws li cov ntsiab cai no siv nyob rau hauv lub punched daim kab xev. Lawv lub qhov txhab mus rau ib tug spool, coj mus tsawg qhov chaw, tiam sis feem ntau raug torn thiab tsis pub koj mus ntxiv thiab hloov cov ntaub ntawv.

muag nthas

muag nthas tsos yog ib tug txhob nyob rau hauv ntaub ntawv technology. Compact, high-muaj peev xwm, lawv cia koj mus cia 300 KB nyob rau hauv qhov ntxov tshaj plaws kuaj txog li 1,44 MB ntawm qhov tseeb versions. Nyeem ntawv thiab sau tau nqa tawm nyob rau hauv ib tug sib nqus disk uas xa tuaj nrog nyob rau hauv ib lub hnab yas cov ntaub ntawv.

Lub ntsiab drawback ntawm muag nthas yog tus fragility ntawm cov ntaub ntawv khaws tseg rau lawv. Lawv lam tau lam ua los ntawm cov teebmeem ntawm electromagnetic teb , thiab yuav demagnetized txawm nyob rau hauv pej xeem thauj - lub tsheb npav los yog tram, yog li lawv tau sim yuav tsum tsis txhob siv sij hawm ntev cia ntawm cov ntaub ntawv. Readout tshwm sim nyob rau hauv muag nthas disk drives. Nws yog thawj zaug 5-nti muag nthas disk, thiab ces lawv hloov los ntawm ntau yooj yim 3-nti.

Lub ntsiab competitor ntawm muag nthas disks tau ua flash drives. Lawv tsuas yog drawback yog tus nqi, tab sis, nrog rau cov kev loj hlob ntawm microelectronics nqi ntawm flash drives thiab diskettes poob dramatically ploj mus cia nyob rau hauv keeb kwm. Thaum kawg lawv ceased ntawv nyob rau hauv 2011.

streamers

Rau khaws cia archived cov ntaub ntawv yav tas los siv daim kab xev drives. Lawv zoo ib yam li cov kev yees duab externally thiab nyob rau hauv hauv paus ntsiab lus ntawm kev txiav txim. Sib Nqus daim kab xev thiab ob reels tso cai ib tug zoo sib xws nyeem thiab sau ntaub ntawv. Lub peev xwm ntawm cov pab kiag li lawm yog txog li 100 MB. Loj muab faib rau ntawm tej drives yog tsis tau txais. End neeg siv xav kom cia lawv cov ntaub ntawv nyob rau hauv ib qho nyuaj drives, thiab suab paj nruag, movies, cov kev pab cuam twb yooj yim los tuav nyob rau hauv CD-, thiab tom qab ntawd DVD-ROM.

CD thiab DVD

Cov cia xov xwm tseem siv niaj hnub no. Nyob rau yas substrate yog thov rau ib tug active, paab thiab kev tiv thaiv txheej. Cov ntaub ntawv yog nyeem los ntawm cov disk nrog ib tug laser beam. Standard disc muaj ib tug muaj peev xwm ntawm 700 MB. Qhov no yog txaus rau piv txwv rau sau ib 2-teev movie nyob rau ntawm ib tug nruab nrab zoo. Tseem muaj ob mog discs, thaum lub active txheej yog tso rau ob sab ntawm lub disc. Yuav kom txuag tau ib tug me me npaum li cas ntawm cov ntaub ntawv siv los ntawm lub mini-CD. Tsav phau ntawv rau cov computer khoom uas tam sim no sau rau lawv.

DVD-discs tau hloov lub CD nyob rau hauv 1996. Lawv cia koj mus cia ntaub ntawv muaj ib tug ntim ntawm 4.7 GB. Lawv meej mom kuj yog tias cov DVD-ROM tsav yuav nyeem ob leeg CD-, thiab DVD-discs. Thaum lub caij, nws yog ib lub loj nco cia ntaus ntawv.

flash Drives

CD thiab DVD drives sib tham saum toj no muaj ib tug xov tooj ntawm zoo - tsis muaj nqi, kev cia siab thiab muaj peev xwm cia loj nyiaj ntawm cov ntaub ntawv, tab sis lawv yog tsim rau ib cov ntaubntawv povthawj siv. Nyob rau hauv kaw disc yuav tsis hloov, ntxiv los yog tshem tawm superfluous. Thiab ntawm no peb tuaj mus rau cov kev pab ntawm ib tug fundamentally sib txawv tsav - flash nco.

Rau ib txhia lub sij hawm nws tau sib nrog diskettes, tab sis sai sai yeej cov haiv neeg. nqi tseem yog ib tug loj deterrent, tab sis tam sim no nws tau raug txo mus rau ib qho taus. Niaj hnub nimno computers tsis txawm peem rau nrog disk drives, li ntawd, USB flash drive tau ua ib tug indispensable luag rau tag nrho cov uas kam nrog computer technology. Qhov siab tshaj plaws nqi ntawm cov ntaub ntawv uas haum rau lub pas, mus txog rau 1 tus kab mob TB.

nco phaib

Tes, cov koob yees duab, e-phau ntawv, yees duab ntas thiab ntau npaum li cas thov kev nco cia. Vim hais tias ntawm lawv cov kuj loj loj rau lub hom phiaj no yog tsis haum USB-drives. Nco phaib yog tsim rau tej tus neeg mob. Nyob rau hauv qhov tseeb, nws yog ib yam flash tsav, tab sis nruj heev heev rau tus me me luaj li cas ntawm cov khoom. Feem ntau ntawm cov sij hawm ntawm lub cim xeeb daim ntawv yog muab cia rau hauv lub tshuab hluav taws xob ntaus ntawv thiab muab tshem tawm tsuas yog rau cov hloov sau cov ntaub ntawv rau mus tas li cab kuj.

Muaj ntau ntau cov qauv kev nco phaib, feem ntau ntawm lawv muaj ib tug tej yam me me luaj li cas ntawm 14 los ntawm 12 hli. Nyob rau niaj hnub computers es tsis txhob ntawm tus tsav yog feem ntau muab tso rau daim ntawv kev nyeem ntawv, uas tso cai rau koj mus nyeem feem ntau hom nco phaib.

Hard disk drives (HDD)

Cia nco rau koj lub computer yog ib tug nyuaj tsav. Hauv nws, muaj hlau daim hlau, nrog ob sab coated magnetic muaj pes tsawg leeg. Lub cev muaj zog rotates ntawm ib tug ceev ntawm 5400 rau cov laus ua qauv los yog 7200 Rev. / min - rau niaj hnub pab kiag li lawm. Lub magnetic lub taub hau tsiv los ntawm qhov chaw mus rau lub ntug thiab tso cai rau koj mus nyeem thiab sau ntawv ntxiv. Lub volume ntawm lub hard disk nyob rau hauv lub xov tooj ntawm disks nyob rau hauv nws. Tam sim no cov qauv yuav khaws mus txog rau 8 tus kab mob TB ntxiv.

Raug nyob rau hauv no hom ntawm lub cim xeeb cia yog yuav luag tsis muaj - qhov no yog ib tug heev txhim khu kev qha thiab check khoom. Nco Tsev nqi nyob rau hauv ib qho nyuaj drives yog lub pheej yig tshaj ntawm tag nrho cov tsav yam.

Khoom hauv lub xeev drives (SSD)

Tsis muaj teeb meem li cas nyuaj drives yog zoo, tab sis lawv muaj yuav luag txog lawv qab nthab. Lawv ceev nyob rau ntawm lub muab ceev drives, thiab ntxiv ntau zuj zus nws tau nyob rau hauv ib lub cev deformation. Flash technology, uas yog siv nyob rau hauv qhov siv thiab ua cov khoom-xeev nco drives, devoid ntawm cov disadvantages. Lawv muaj tsis muaj feem mus thiab yog li ntawd tsis raug mus rau lub cev coj thiab tsim kua muag, yog tsis ntshai poob siab impacts thiab cov suab nrov.

Tab sis, thaum tseem muaj loj drawbacks. Ua ntej ntawm tag nrho - tus nqi. SSD nqi 5 lub sij hawm lub hard disk ntawm zoo xws li cov loj. Lwm tseem ceeb drawback - ib tug me me lub sij hawm ntawm lub lag luam. SSDs yog feem ntau xaiv rau nruab operating system thiab lub zog tsav yog siv los khaws cov ntaub ntawv. Tus nqi ntawm cov SSDs tau tshee koos, muaj kev kawm thiab kev nce nyob rau hauv lawv cov kev pab. Nyob rau hauv lub nyob ze yav tom ntej lawv yuav tau oust cov tsoos hard disk drives, raws li nyob rau hauv nws lub sij hawm thawb lub pas diskettes.

lwm Hard Drives

Internal cia thiab cim xeeb nrog yog tag nrho cov zoo, tab sis feem ntau yuav tsum mus rau cov hloov ntaub ntawv los ntawm ib lub computer mus rau lwm lub. Rov qab nyob rau hauv 1995 nws tsim ib tug USB interface, uas koj mus txuas rau ib PC ib tug ntau yam ntawm pab kiag li lawm, tsis muaj kev zam, thiab nco cia kiag li lawm. Chiv, nws yog flash drives, thiab tom qab ntawd nyob DVD-players c USB-connector thiab, thaum kawg, HDD thiab SSD drives.

USB-interface yog txaus nyiam nyob rau hauv nws cov simplicity - cia li ntsaws rau hauv ib tug USB flash drive los yog lwm yam cia ntaus ntawv, thiab koj yuav ua hauj lwm, tsis yuav tsum tau tej neeg tsav tsheb installation los yog lwm yam ntxiv ua. Cov kev loj hlob ntawm lub interface thiab thawj zaug tsos ntawm USB 2.0, thiab USB 3.0, thiab ces dramatically nce cov kev ceev ntawm cov ntaub ntawv pauv ntawm no lub channel. lwm disk ua tau zoo yog tam sim no sib txawv me ntsis los ntawm cov internal, thiab lawv loj yuav tsis tsis haum. Sab nraud nco Drive fits tau yooj yim nyob rau hauv lub Palm ntawm koj txhais tes, thaum nws tso cai rau koj los khaws pua pua ntawm gigabytes ntawm cov ntaub ntawv.
