Ib qho piv txwv ntawm kev nkag mus ua ntu zus yog nrog atape tsav, qhov twg ntaus ntawv yuav tsum txav daim kab xev ribbonforward lossis rov qab mus cuag cov ntaub ntawv xav tau. Qhov opposite yuav yog RAM (Random Nkag mus Nco) uas tuaj yeem mus qhov twg ntawm lub nti mus nkag mus cov ntaub ntawv.

Tom qab ntawd, dab tsi yog cov khoom siv sib txuas thiab kev nkag ncaj qha?

Cov ntaub ntawv tseem ceeb xws li semiconductor nco chips raug hu kev nkag ncaj qha nco los yog random- nkag mus nco (RAM). Sib nqus disk khoom siv nquag hu kev nkag ncaj qha khaws cia khoom siv (DASDs). Nyob rau hauv sib piv, xov xwm xws li magnetic daim kab xev cartridges yog hu ua cov khoom siv sib txuas.

Cov cuab yeej khaws cia twg siv cov khoom siv sib txuas? Sib nqus daim kab xev yog qhov ntau sequential access storagedevice.

Tsis tas li ntawd, txoj kev nkag mus tau yog dab tsi?

Hauv computer science, kev nkag mus ua ntu zus txhais tau hais tias ib pawg ntawm cov ntsiab lus (xws li cov ntaub ntawv hauv lub cim xeeb array lossis disk fileor ntawm cov ntaub ntawv sib nqus cov ntaub ntawv khaws cia) yog nkag mus nyob rau hauv apredetermined, txiav txim ib theem zuj zus. Kev nkag mus ua ntu zus yog qee zaum tib txoj kev nkag mus cov ntaub ntawv, piv txwv li yog nyob rau ntawm daim kab xev.

Daim ntawv teev npe ua ntu zus yog dab tsi?

Ib yam uas yog ua ntu zus feem ntau ua raws li tus lej lossis cov tsiaj ntawv, tab sis nws kuj tuaj yeem piav qhia txog yam uas tsis suav nrog tab sis tseem yuav tsum tau ua nyob rau hauv qhov kev txiav txim siab, xws li ua ntu zus cov kauj ruam koj ua raws rau khiav aprogram ntawm koj lub computer. Cov ntsiab lus ntawm ua ntu zus.

Dab tsi yog qhov txawv ntawm cov ntaub ntawv davhlau ya nyob twg cov cuab yeej DTE thiab cov khoom siv sib txuas lus DCE)?

DTE (Data terminating equipment) thiab DCE (Data circuit terminating equipment) yog hom kev sib txuas lus serial. DTE yog ib qho khoom siv uas tuaj yeem ua tau raws li binary digital cov ntaub ntawv los yog qhov chaw.
