Hauv engineering, redundancy yog qhov kev sib tw ntawm cov khoom tseem ceeb lossis kev ua haujlwm ntawm lub cev nrog lub hom phiaj ntawm kev txhim kho kev ntseeg siab ntawm lub kaw lus, feem ntau yog nyob rau hauv daim ntawv thaub qab lossis tsis muaj kev nyab xeeb, lossis txhim kho qhov kev ua tau zoo, xws li hauv rooj plaub ntawm GNSS txais, lossis ntau xov lub computer ua.
Tom qab ntawd, dab tsi yog redundancy?
Rov qab yog thaum tus tswv hauj lwm txo lawv cov neeg ua hauj lwm vim tsis muaj hauj lwm los yog hauj lwm lawm. Txawm li cas los xij, yog tias koj poob koj txoj haujlwm thiab lawv tau txais ib tus neeg los sau nws qhov tsis yog redundancy …
Kuj Paub, dab tsi yog redundancy dab tsi Cheebtsam yuav muaj redundancy? Rov qab hais txog kev tsim qauv qhov twg a tiv thaiv yog duplicated thiaj li hais tias nyob rau hauv cov kev tshwm sim ntawm a tiv thaiv tsis ua hauj lwm, IT khoom tsis cuam tshuam. Piv txwv li, muaj tsis tu ncua muaj zog yog tias muaj hluav taws xob poob. Lub hom phiaj tseem ceeb ntawm redundancy yog los xyuas kom zero downtime, txawm nyob rau hauv cov xwm txheej phem tshaj plaws.
Tsis tas li ntawd, dab tsi yog redundancy thiab nws hom?
Rov qab . General txhais ntawm redundancy yog tshaj qhov qub. Txawm li cas los xij, hauv kev suav, lo lus tau siv tshwj xeeb thiab hais txog cov khoom siv thev naus laus zis uas siv rau lub hom phiaj thaub qab. Muaj ntau hom ntawm redundant khoom siv. Feem ntau hauv kev suav tus kheej yog lub cuab yeej khaws cia.
Dab tsi yog redundancy hauv server?
Server redundancy hais txog tus nqi thiab kev siv ntawm thaub qab, tsis ua haujlwm lossis redundant servers nyob rau hauv ib puag ncig kev suav.

Dab tsi yog qhov txawv ntawm redundancy thiab resilience?
Redundancy txhais cov kev xa tawm lossis kev muab cov khoom siv sib npaug lossis cov tshuab hauv cov chaw tseem ceeb los ua haujlwm ua haujlwm yog tias cov cuab yeej tseem ceeb lossis lub kaw lus tsis ua haujlwm. Resiliency txhais tau tias muaj peev xwm rov qab los, sib koom ua ke lossis kho tus kheej kom rov ua haujlwm li qub tom qab muaj kev cuam tshuam
Dab tsi yog computer science algorithms?
Ib qho algorithm yog cov txheej txheem zoo uas tso cai rau lub computer los daws qhov teeb meem. Ib qho teeb meem tshwj xeeb feem ntau tuaj yeem daws tau los ntawm ntau tshaj ib qho algorithm.Optimization yog tus txheej txheem ntawm kev nrhiav cov txiaj ntsig zoo tshaj plaws rau ib txoj haujlwm
