Muaj tseeb, txhua tus neeg siv ntawm lub khoos phis tawm ntawm tus kheej siv ntau lub chaw cia khoom, xws li flash drive, disks, thiab lwm yam. Hmoov tsis zoo, tsis yog txhua tus paub ua raws nraim li cov cuab yeej no sawv cev rau lub cim xeeb sab nraud.
Dab Tsi Sab Nraud Yog Dab Tsi?
Kev nco sab nraud yuav tsum to taub raws li hom kev nco ntawm tus kheej lub computer, uas tau siv los siv ntau cov cuab yeej sab nraud muaj peev xwm khaws cov ntaub ntawv ntau rau lub sijhawm ntev. Kev khaws khoom sab nraud, hauv kev sib piv nrog lub cim xeeb sab hauv ntawm lub khoos phis tawm, piv txwv li, nkag mus siv lub cim xeeb, muaj lub ntim loj, tab sis tib lub sij hawm tus nqi hloov ntaub ntawv tsawg.
Cov cim tshwj xeeb sab nraud thiab cov khoom siv
Muaj ntau ntau ntawm cov khoom siv sab nraud cia hnub no. Hais txog lub khoos phis tawj ntiag tug, lawv tuaj yeem ua: hard disks (ob sab nraud thiab sab hauv), floppy disks, uas yog npaj tshwj xeeb rau kev nyeem ntawv thiab sau ntawv, laser disks, streamers, flash cards, etc. Txhua cov khoom siv no sib koom los ntawm hom kev nkag mus rau cov ntaub ntawv. Cov no tuaj yeem yog: nkag ncaj qha khoom siv, nrog rau cov khoom nkag ua ntu zus. Lawv sib cais los ntawm qhov tseeb tias nyob rau hauv cov khoom siv ntawm kev nkag mus ncaj qha, lub sijhawm ntawm kev nkag mus rau cov ntaub ntawv tsis nyob ntawm nws qhov chaw ntawm tus neeg nqa khoom, thiab hauv cov khoom siv ntawm cov kev nkag mus txuas ntxiv, xws li muaj kev cia siab. Tus lej ntawm lub cim xeeb ntawm cov khoom siv nyuaj (hauv sab nraud thiab sab hauv) tuaj yeem txog ob peb terabytes. Qhov ntim ntawm qhov muag ntog disk feem ntau tsis tshaj li 1.44 MB (niaj hnub no lawv tsis siv). CD-drives muaj lub zog ntawm 640 megabytes, thaum DVD tseem muaj peev xwm txog 17 gigabytes. Qhov feem ntau ntawm USB-tsav hnub no nce mus txog 64 GB.
Raws li rau cov yam ntxwv tseem ceeb ntawm kev nco sab nraud, cov no yog lawv cov ntaub ntawv muaj peev xwm, nrawm, kev ntseeg tau ntawm cov ntaub ntawv khaws cia, nrog rau nqi. Lub peev xwm yuav tsum nkag siab qhov siab kawg ntawm cov ntaub ntawv uas tuaj yeem muab sau cia ntawm lub cuab yeej. Nws yuav tsum raug sau tseg tias, raws li txoj cai, nws yog qhov loj dua qhov muaj peev xwm ntawm lub cim xeeb sab hauv. Hmoov tsis zoo, kev ceev lossis kev ua tiav ntawm cov khoom siv no muaj ntau lub sij hawm qis rau lub cim xeeb sab hauv. Nws yog txiav txim siab los ntawm lub sijhawm nkag, kaw thiab nyeem cov ntaub ntawv khaws tseg hauv lub cuab yeej. Nyob rau hauv cov nqe lus ntawm kev cia siab, qhov no parameter yuav luag zoo tib yam rau lub cim xeeb sab hauv. Kev cia siab tau tsuas yog tso tseg thaum tsis raug los saib tsis xyuas siv lub cim xeeb sab nraud, nrog rau qhov muaj ntau cov software siab phem.
