Qhov chaw ntawm disks thiab Sib nqus tapes yog coated nrog ntau lab ntawm cov hlau me me kom cov ntaub ntawv tuaj yeem ua tau khaws cia ntawm lawv. Cov ntawv sau / nyeem lub taub hau ntawm disk tsav los yog daim kab xev tsav muaj electromagnets uas tsim Sib nqus teb nyob rau hauv lub hlau ntawm lub khaws cia nruab nrab thaum lub taub hau hla lub disk lossis daim kab xev.
Tsis tas li ntawd, cov khoom sib nqus ua haujlwm li cas?
Sib nqus cia los yog sib nqus kaw yog cov khaws cia ntawm cov ntaub ntawv nyob rau hauv ib tug magnetized nruab nrab. Sib nqus cia siv cov qauv sib txawv ntawm magnetisation hauv cov khoom siv magnetisable los khaws cov ntaub ntawv thiab yog ib daim ntawv uas tsis yog-volatile nco . Cov ntaub ntawv nkag mus siv ib lossis ntau dua nyeem / sau taub hau.
Tsis tas li ntawd, cov cuab yeej sib nqus yog dab tsi? Sib nqus cia yog ib txoj hauv kev pheej yig tshaj los khaws cov ntaub ntawv ntau. Sib nqus cia siv ob hom ntawm Sib nqus polarities los sawv cev rau cov ntaub ntawv binary uas muaj zeros thiab ib qho. Feem ntau siv cov khoom siv uas siv sib nqus cia suav nrog Sib nqus daim kab xev, floppy disks thiab hard-disk drives.
Ib yam li ntawd, lub magnetic disk khaws cov ntaub ntawv li cas?
A Sib nqus disk yog a khaws cia ntaus ntawv uas siv cov txheej txheem magnetization los sau, rov sau dua thiab nkag mus cov ntaub ntawv . Nws yog them nrog a Sib nqus txheej thiab khaws cov ntaub ntawv nyob rau hauv daim ntawv ntawm lem, me ntsis thiab sectors. Nyuaj disks , zip disks thiab floppy disks yog cov piv txwv ntawm magnetic disks.
Yuav txhim khu kev qha magnetic cia?
Hauv cov ntsiab lus no, Sib nqus tapes yog tam sim no nyob ib tug thib ob hluas hluas. Qhov kev daws teeb meem no tau raug pov thawj thiab ruaj khov - tau ntau xyoo nws tau siv rau cov ntaub ntawv khaws cia thiab suav tias yog kev nyab xeeb thiab tsis tshua muaj neeg ntseeg tau . Nyob rau hauv lub sij hawm ntawm nias kom zoo dua hardware tsis, tshwj xeeb tshaj yog ceev, tapes tau kwv yees yuav ploj mus sai sai.
Pom zoo:
Puas txhais tau tias yog kev sib raug zoo ntawm cov khoom ntawm ib yam khoom thiab lub peev xwm ntawm tus neeg sawv cev uas muab cov lus qhia rau kev siv cov khoom?
Kev them nyiaj yog kev sib raug zoo ntawm cov khoom ntawm ib yam khoom thiab lub peev xwm ntawm tus neeg sawv cev uas txiav txim siab seb qhov khoom siv tau li cas
Dab tsi ntawm cov hauv qab no yog qhov txiaj ntsig ntawm lub xeev cov khoom siv hluav taws xob sib nqus hard drive?
HDD tseem pheej yig dua SSD, tshwj xeeb tshaj yog rau cov tsav tshaj 1 TB. SSD tsis muaj qhov txav txav. Nws siv lub cim xeeb flash los khaws cov ntaub ntawv, uas muab kev ua tau zoo dua thiab kev ntseeg tau ntawm HDD. HDD muaj cov khoom txav thiab cov hlau nplaum sib nqus, txhais tau tias lawv siv ntau dua, lawv hnav sai dua thiab ua tsis tiav
Ib qho piv txwv ntawm cov khoom siv sib nqus yog dab tsi?
Feem ntau siv cov khoom siv uas siv cov khoom sib nqus muaj xws li daim kab xev sib nqus, floppy disks thiab hard-disk drives
Cov ntaub ntawv khaws cia hauv cov khoom siv sib nqus li cas?
Magnetic storage lossis magnetic recording yog qhov khaws cia ntawm cov ntaub ntawv ntawm qhov nruab nrab magnetized. Sib nqus cia siv cov qauv sib txawv ntawm magnetisation nyob rau hauv cov khoom siv magnetisable los khaws cov ntaub ntawv thiab yog ib daim ntawv uas tsis yog-volatile nco. Cov ntaub ntawv nkag mus siv ib lossis ntau dua nyeem / sau taub hau
Cov cuab yeej khaws cia hom twg yog cov xov xwm sib nqus uas yog lub xeev kho qhov muag?
Lub xeev muaj zog? Hard-drives feem ntau yog sib nqus xov xwm, CD drives yuav luag ib txwm optical drives, flash drives yog lub ntsiab thiab feem ntau hom khoom slate media
