Secondary nco muaj nyob rau hauv ntau thiab ib txwm loj dua lub cim xeeb tseem ceeb . Lub computer tuaj yeem ua haujlwm yam tsis muaj lub cim xeeb thib ob raws li nws ib sab nraud nco . Cov piv txwv ntawm lub cim xeeb thib ob yog lub hard disk, floppy disk, CD, DVD, thiab lwm yam.
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog qhov tseem ceeb lossis kev nco qab thib ob?
Qhov txawv ntawm Lub cim xeeb tseem ceeb thiab Secondary Memory . Lub cim xeeb tseem ceeb yog lub ntsiab nco ntawm lub khoos phis tawj uas tuaj yeem nkag ncaj qha los ntawm lub chaw ua haujlwm hauv nruab nrab, whereas lub cim xeeb theem nrab hais txog cov cuab yeej cia sab nraud uas tuaj yeem siv los khaws cov ntaub ntawv lossis cov ntaub ntawv mus tas li.
Qhov piv txwv thib ob yog dab tsi? Secondary nco hais txog cov khoom siv cia, xws li hard drives thiab hard state drives. Nws kuj tseem tuaj yeem xa mus rau cov xov xwm tshem tawm, xws li USB flash drives, CDs, thiab DVDs. Rau piv txwv , lub computer yuav muaj ib tug terabyte hard drive, tab sis tsuas yog 16 gigabytes ntawm RAM.
Hais txog qhov no, thawj qhov cim xeeb muab piv txwv li cas?
Ib qho piv txwv ntawm Lub cim xeeb tseem ceeb yog RAM thiab ROM uas khaws cov kev pab cuam. Cov no nco muaj peev xwm txwv thiab tsim los ntawm kev siv cov khoom siv sib xyaw ua ke (IC) lossis cov khoom siv hluav taws xob semiconductor. Nws ceev ntawm cov ntaub ntawv nkag tau sai dua qhov thib ob nco . Nws yog ntau. kim tshaj theem nrab nco.
Dab tsi yog qhov txawv ntawm thawj lub cim xeeb thiab qhov chaw cia nruab nrab?
Qhov sib txawv ntawm qhov chaw khaws cia thiab theem nrab cia . Lub cim xeeb tseem ceeb yog cov lub ntsiab nco (Hard disk, RAM) qhov twg lub operating system nyob. Secondary nco tuaj yeem ua lwm yam khoom siv xws li CD, floppy magnetic discs thiab lwm yam. theem nrab cia tsis tuaj yeem nkag ncaj qha los ntawm CPU thiab tseem yog sab nraud nco cia.
Pom zoo:
Dab tsi yog qhov tseem ceeb khaws cia lub rooj hauv Oracle nrog piv txwv?
Lub rooj tseem ceeb khaws cia yog lub hauv paus rooj nrog ib-rau-ib kab kev sib raug zoo nrog cov kab hauv kev pom, ntawm tus yuam sij tseem ceeb lossis tus yuam sij tshwj xeeb. Hauv qhov piv txwv saum toj no, lub rooj tsheb yog lub rooj tseem ceeb
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
Tus yuam sij tseem ceeb thib ob thiab tus yuam sij txawv teb chaws yog dab tsi?
Txawv Teb Chaws Tseem Ceeb: Yog Lub Ntsiab Tseem Ceeb ib lub rooj tshwm (hloov-hais) hauv lwm lub rooj. Secondary (los yog lwm txoj kev) Key: Puas yog ib qho chaw hauv lub rooj uas tsis raug xaiv los ua ib qho ntawm ob hom saum toj no
Lub cim xeeb tseem ceeb yog dab tsi?
Lub cim xeeb tseem ceeb yog lub cim xeeb hauv computer uas nkag ncaj qha los ntawm CPU. Qhov no suav nrog ntau hom kev nco, xws li processor cache thiab system ROM.RAM, lossis random access memory, muaj ib lossis ntau lub cim xeeb modules uas khaws cov ntaub ntawv ib ntus thaum lub computer khiav haujlwm
Lub hom phiaj ntawm lub cim xeeb tseem ceeb yog dab tsi?
Lub cim xeeb tseem ceeb hauv lub computer hu ua Random Access Memory. Nws tseem hu ua RAM. Qhov no yog ib feem ntawm lub khoos phis tawj uas khaws cov kev khiav haujlwm software, cov ntawv thov software thiab lwm yam ntaub ntawv rau lub hauv paus ua haujlwm (CPU) kom muaj kev nkag tau sai thiab ncaj qha thaum xav tau los ua haujlwm
