Yuav ua li cas yog ib tug hard disk drive

Txawm tias muaj tseeb hais tias txawm nyob lub tsev kawm ntawv cov tshooj lus ntawm computer science xib fwb qhia txog ib tug nyuaj tsav nyob rau hauv lub ntiaj teb no network yog feem ntau hais lo lus nug no. Ib txhia tau mloog zoo piav, lwm leej lwm tus twb xav. Nyob rau hauv no tsab xov xwm, peb rov qab ntev tsis nco qab lawm - qhia rau koj yog dab tsi lub zog tsav.

Yog vim li cas, nyob rau hauv qhov tseeb, hard disk yog muaj npe? Lub sij hawm originated nyob rau hauv thaum ntxov hnub ntawm txoj kev loj hlob xam, thaum punch phaib twb muab txoj kev uas yuav sib nqus tapes thiab muag nthas disks, thiab CDs tseem tsis tau tshwm. Tej zaum muaj ntau yam ntawm hnub no lub computer tswv twb tsis paub dab tsi ib muag nthas disk, thiab yuav ua li cas lawv ntsia. Tab sis tsis muaj kev xav, nws yog tsis yooj yim sua kom muab ib lo lus teb rau lo lus nug ntawm yog dab tsi lub hard disk. Lub magnetic daim kab xev (raws li nyob rau hauv cov suab daig kab) raws li ib cov cab kuj los ntawm cov ntaub ntawv ntawd kub ntev li ntev - zaj duab xis footage tsis pub rau sai sai nrhiav ib yam feem. Lawv hloov los ntawm muag nthas disks. Lawv yog cov polymer disks nrog ob tog loj nrog ib tug sib nqus txheej. Nws yuav lam xav tias lub daig kab kab xev cia li melted mus rau hauv lub disc. Yuav kom tiv thaiv khawb, nws twb muab tso rau hauv ib lub square zoo li tus opaque yas hnab ntawv - tau txais ib muag nthas disk. Cov ntaub ntawv yog nyeem tawm tsav. muag nthas zog yog me me - nws yuav muab tau yooj yim khoov duav (daim ntawv zoo tu qab tso), thiab txawm ntau quav tso nyob rau hauv ib nrab. Ob tus thawj thiab tus thib ob yog tsis yooj yim sua rau ua - nws leads mus rau nto uas tsis vim puas mus rau lub sib nqus txheej (tshwj xeeb tshaj yog nyob rau khoov). Nws yog ib qho tseem ceeb tias cov muag nthas disk lub npe hu ua lub KMT - muag nthas disks.

Nyob rau tib lub sij hawm, nws muaj kis tshwj xeeb electromechanical ntaus ntawv yog ib tug nws yog xim hlau los yog iav disk coated nrog ib tug sib nqus (chromium oxide), ib tug Rotatable lub cev muaj zog tsev nyob nrog ib tug tsis tu ncua ceev. Cov hluav taws xob yog ib feem ntawm lub Circuit Court ntawm tau txais nyeem commands \ ntaubntawv povthawj siv rau computer. Tsis zoo li muag nthas disks yog hais cov nram qab no: ib tug loj npaum li cas volume, siab ntseeg, kev kawm ntawv, tsis muaj peev xwm mus khoov, vim hais tias lub cev, thiab tus tsav nws tus kheej yog hlau.

Yuav ua li cas yog lub hard drive? Nws yog hais tias ntaus ntawv - cov HDD (cia raws li magnetic nyuaj disks). Lwm yam npe - HDD, nyuaj tsav, thiab lwm yam

Niaj hnub nimno nyuaj drives muaj ob peb disks rau ib qho axis, yog li ua tag nrho cov ntim. Tsis zoo li cov cassettes, lub nyeem lub taub hau thaum lub sij hawm kev lag luam yog tsis nyob rau hauv kev sib cuag nrog cov nto thiab yoov rau ntawm huab cua kis (tsis ntau tshaj 10 nm). Cov kev ceev ntawm kev sib hloov nyob rau hauv lub ceev: feem ntau ntawm cov neeg rau zaub mov qauv so drives mus txog 15,000 Rev. / min, ib unspoken txheem - 7200, thiab tus nqi ntau ntau yam "yog cov ntsiab lus nrog coj tus" 5400. Txawm tias tsis ntev los no ntse lub HDD, ib tug stepwise hloov ceev nyob rau hauv lub load.

Interface kev twb kev txuas mus rau ib tug computer -. IDE, SATA, USB, SAS, thiab lwm yam Xa mus rau cov USB, peb tsis tau hais tias xws li ib tug sab nraud nyuaj tsav.

Nrog rau tag nrho cov kev pab cuam ntawm ib qho nyuaj drives, lawv tau ntev lawm lub internal Cheebtsam ntawm lub computer, nyob rau hauv lub system unit. Modernization chaw nres tsheb thaj tsam (magnetic latch lub taub hau carriage, tus neeg kho tshuab QHAIB) manufactured pub HDD portable. Qhov no yog tib yam nyuaj tsav, tab sis tsim los yog xav paub ntau demanding tej yam kev mob. Lub tsev nyob tsis muaj qhib blocks ntawm electronics. Kev cob cog rua lub computer ntawm USB los yog FireWire. Ntxaiv ceev yog feem ntau yog tas rau 5400 Rev. / min (txo hwj chim noj).
