Teb: ECC (Yuam Kev Kho Code) nco yog parity nco thiab tsis yog - ECC nco yog tsis yog -parity. Qee qhov chaw hais tias koj ua tau txawm sib tov ob hom RAM thiab cov ECC RAM yuav ua haujlwm li tsis yog - ECC nco . Txawm li cas los xij, feem ntau nco tuam txhab ua tsis txhawb kev sib xyaw ntawm ob hom, yog li sim nws ntawm koj tus kheej qhov pheej hmoo.
Tom qab ntawd, ib tus tuaj yeem nug, qhov txawv ntawm ECC thiab tsis yog ECC lub cim xeeb yog dab tsi?
Qhov txawv ntawm ECC thiab Non - ECMemory . ECC stands rau "yuam kev kho code." Likeparity nco , ECC nco ntes thiab ceeb toom nco yuam kev. Txawm li cas los xij, thaum parity tsuas tuaj yeem txheeb xyuas qhov yuam kev, ECC tuaj yeem kho qhov yuam kev yam tsis cuam tshuam lwm yam haujlwm ntawm koj lub cev.
Ib yam li ntawd, ECC nco siv rau dab tsi? yuam kev-kho code nco ( ECC nco ) yog ib hom computer cov ntaub ntawv khaws cia uas tuaj yeem kuaj xyuas thiab kho lawv feem ntau ntawm cov ntaub ntawv hauv kev noj nyiaj txiag. ECC nco yog siv hauv feem ntau cov khoos phis tawj uas cov ntaub ntawv kev noj nyiaj txiag tsis tuaj yeem cuam tshuam rau txhua qhov xwm txheej, xws li rau kev suav nyiaj txiag.
Kuj Paub, puas ECC nco ua qhov txawv?
ECC RAM yog txawv raws li nws muaj ntxiv nco nti uas ua raws li ob qho tib si kev tshawb nrhiav thiab kho rau lwm yim RAM chips. Hloov ntawm ib qho me ntsis rau txhua 8 cov ntaub ntawv, ECC siv 7 ntsis codethat yog cia li generated rau txhua txhua 64 khoom ntawm datathat yog khaws cia hauv RAM.
ECC puas xav tau kev nco?
Hmoov zoo, nco yuam kev tsis tshua muaj nyob rau niaj hnub no nco chips, yog li feem ntau cov neeg siv nruab nrab tsis muaj xav tau rau ECC . Yog tias koj tab tom npaj siv koj qhov system ua server lossis lwm lub tshuab "lub hom phiaj tseem ceeb", peb pom zoo ECC.
