Muaj ob hom kev cia khoom siv nrog cov khoos phis tawj: cov khoom siv tseem ceeb, xws li RAM, thiab cov khoom siv thib ob, xws li nyuaj tsav. Secondary cia yuav tshem tau, sab hauv, los yog sab nraud.
Optical cia khoom
- Blu-duab tshav disc.
- CD-ROM disc.
- CD-R thiab CD-RW disc.
- DVD-R, DVD+R, DVD-RW, thiab DVD+RW disc.
Tsuas yog li ntawd, 4 hom kev cia khoom yog dab tsi?
Kev txhais thiab hom kev cia khoom

- DVD-ROM.
- flash media.
- "thumb" tsav.
- nco nco.
- iPOD.
- lub koob yees duab digital.
Ib sab saum toj no, 3 hom kev cia khoom yog dab tsi? Muaj peb yam tseem ceeb ntawm khaws cia khoom siv: optical, magnetic thiab semiconductor. Qhov ntxov tshaj ntawm cov no yog cov khoom siv hlau nplaum. Computer systems pib nrog hlau nplaum khaws cia nyob rau hauv daim ntawv ntawm tapes (yog, ib yam li ib tug cassette los yog video daim kab xev). Cov no kawm tiav rau lub hard disk drive thiab ces mus rau floppy disk.
Hais txog qhov no, cov piv txwv ntawm cov cuab yeej khaws cia yog dab tsi?
Cov khoom siv cia yog siv los khaws cov ntaub ntawv thiab cov lus qhia mus tas li. Cov khoom siv cia kuj hu ua theem nrab cov khoom siv cia / thaub qab cov khoom siv cia / sab nraud cov khoom siv cia los yog pab cov khoom siv cia . Piv txwv ntawm cov khoom siv cia suav nrog Hard Disk, CD thiab DVD thiab lwm yam. Sib nqus daim kab xev yog qhov qub khoom cia.
Dab tsi yog qhov khoom siv cia?
A khoom cia yog ib qho khoom siv hauv computer uas siv rau khaws cia, porting thiab rho tawm cov ntaub ntawv thiab cov khoom. Nws tuaj yeem tuav thiab khaws cov ntaub ntawv ib ntus thiab mus tas li, thiab tuaj yeem ua sab hauv lossis sab nraud rau lub computer, server lossis lwm yam kev suav. ntaus ntawv.
Pom zoo:
Dab tsi yog processor thiab thawj cov khoom siv cia?
Hauv qhov no, thawj qhov chaw khaws cia feem ntau yog hais txog kev nkag mus rau lub cim xeeb (RAM), thaum qhov chaw cia nruab nrab yog hais txog lub khoos phis tawj lub hard drive sab hauv. RAM, feem ntau hu ua 'nco' yog suav tias yog thawj qhov chaw cia, txij li nws khaws cov ntaub ntawv ncaj qha los ntawm lub computer CPU
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 yog qhov khoom siv ntau tshaj plaws khaws cia?
Ntau hom kev khaws cia muaj xws li cov hauv qab no: solid-state drives (SSD) hard drives. sab nraud hard drives. optical tsav. daim kab xev tsav. RAID khaws cia. USB chaw cia khoom. flash memory cards
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
Puas yog lub tshuab luam ntawv laser yog ib qho khoom siv lossis cov khoom siv tawm?
Laser Printers yog cov khoom siv tso zis. Txawm li cas los xij, nyob rau hauv 10 xyoo dhau los los yog li ntawd, ntau lub tshuab luam ntawv kuj tau nruab nrog cov tshuab luam ntawv built-in, tig lawv mus rau hauv I / O cov khoom siv (input / output)
