Feem ntau siv khoom siv uas siv sib nqus cia suav nrog Sib nqus daim kab xev, floppy disks thiab hard-disk drives.
Ib yam li ntawd, nws raug nug, cov khoom siv sib nqus ua haujlwm li cas?
Ib yam li lub hard drive, lub xov xwm siv nyob rau hauv tshem tau Sib nqus - cov khoom siv cia yog coated nrog hlau oxide. Thaum cov ntaub ntawv raug nyeem los ntawm tus tsav, lub taub hau nyeem rub tawm qhov sib txawv Sib nqus teb hla qhov sib txawv, tsim kom muaj qhov sib txawv Sib nqus teb nyob rau hauv lub tub ntxhais thiab yog li ntawd ib tug teeb liab nyob rau hauv lub kauj.
Yuav ua li cas sib nqus cov cuab yeej khaws cov ntaub ntawv? Sib nqus cia los yog Sib nqus recording yog khaws cia ntawm cov ntaub ntawv ntawm qhov nruab nrab magnetized. Sib nqus cia siv cov qauv sib txawv ntawm magnetisation hauv cov khoom siv magnetisable khaws cov ntaub ntawv thiab yog ib daim ntawv uas tsis-volatile nco . Cov ntaub ntawv nkag mus siv ib lossis ntau dua nyeem / sau taub hau.
Tom qab, lo lus nug yog, dab tsi yog magnetic disk nrog piv txwv?
A Sib nqus disk yog ib lub cuab yeej cia uas siv cov txheej txheem magnetization los sau, rov sau dua thiab nkag mus rau 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 muaj ntau piv txwv ntawm magnetic disks.
Puas yog DVD yog ib qho khoom siv sib nqus?
magnetic cia khoom , xws li hard disk drives. kho qhov muag cov khoom siv cia xws li CD, DVD thiab Blu-duab tshav discs. solid state cov khoom siv cia , xws li solid state drives thiab USB memory sticks.

Databases hauv Access yog tsim los ntawm plaub yam khoom: rooj, queries, forms, thiab reports. Ua ke, cov khoom no tso cai rau koj nkag mus, khaws, txheeb xyuas, thiab sau koj cov ntaub ntawv raws li koj xav tau
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
Dab tsi yog qhov sib txawv tseem ceeb ntawm Amazon EBS thim rov qab thiab piv txwv khw Rov qab piv txwv?
Dab tsi yog qhov sib txawv tseem ceeb ntawm Amazon EBS-txhawb thiab qhov piv txwv-khoom txhawb nqa? Amazon EBS-rov qab piv txwv tuaj yeem nres thiab rov pib dua. Instance-store backed instances tuaj yeem nres thiab rov pib dua. Nws pib scaling yuav tsum siv Amazon EBS-rov qab piv txwv
Cov piv txwv ntawm cov khoom siv khaws cia tseem ceeb yog dab tsi?
RAM (random nkag tau lub cim xeeb) thiab cache yog ob qho tib si piv txwv ntawm lub chaw cia khoom. Daim duab qhia peb hom kev khaws cia rau cov ntaub ntawv hauv computer. Thawj qhov chaw khaws cia qhov tseem ceeb sib txawv los ntawm lwm tus yog tias nws nkag tau ncaj qha los ntawm CPU, nws tsis hloov pauv, thiab nws tsis tuaj yeem tshem tau
