Caching algorithm ua tau zoo tshaj plaws yuav yog ib txwm muab cov ntaub ntawv pov tseg uas yuav tsis xav tau rau lub sijhawm ntev tshaj yav tom ntej. Qhov txiaj ntsig zoo no yog hu ua Bélády's optimal algorithm/simply optimal change policy or the clairvoyant algorithm.
Qhov twg zoo dua FIFO lossis LRU?
FIFO khaws cov khoom uas nyuam qhuav ntxiv. LRU yog, feem ntau, ua haujlwm zoo dua, vim tias feem ntau muaj cov khoom nco uas tau ntxiv ib zaug thiab tsis siv dua, thiab muaj cov khoom ntxiv thiab siv ntau zaus. LRU feem ntau yuav khaws cov khoom uas nquag siv hauv nco.
Pab twg hloov algorithm yog qhov ua tau zoo tshaj?
LRU ua rau yog qhov zoo tshaj plaws algorithm rau nplooj hloov pauv los siv, tab sis nws muaj qee qhov tsis zoo. Hauv kev siv algorithm, LRU tuav cov npe txuas ntawm txhua nplooj ntawv hauv lub cim xeeb, uas, nplooj ntawv siv tam sim no tau muab tso rau pem hauv ntej, thiab nplooj ntawv siv tsawg kawg yog muab tso rau tom qab.
LRU lossis MRU twg zoo dua?
LRU stands rau 'tsawg tsis ntev los no siv'. … Li no koj yuav muab cov khoom uas nyuam qhuav siv tsawg tshaj plaws tso tseg ua ntej, yam uas koj tsis tau siv rau ib pliag tab sis nyob hauv qhov chaw siv cache. MRU stands rau 'tsis ntev los no siv'. Thaum koj nkag mus rau cov ntaub ntawv hauv qhov thaiv, qhov cuam tshuam cuam tshuam yuav nkag mus rau hauv MRU kawg ntawm daim ntawv tswj hwm.
yog dab tsiTxoj hauv kev zoo tshaj los xaiv nplooj ntawv hloov algorithm?
Thaum nplooj ntawv uas tau xaiv los hloov thiab nplooj ntawv tawm yog rov hais dua nws yuav tsum tau muab tso rau hauv (nyeem los ntawm disk), thiab qhov no suav nrog tos kom tiav I/O. Qhov no txiav txim siab qhov zoo ntawm nplooj ntawv hloov algorithm: lub sijhawm tsawg dua rau nplooj-ins, qhov zoo dua cov algorithm.

Dab tsi yog qhov hloov pauv thiab hloov pauv hloov pauv?
Point mutations hloov ib leeg nucleotide. Frameshift kev hloov pauv yog ntxiv lossis tshem tawm ntawm nucleotides uas ua rau muaj kev hloov pauv hauv kev nyeem ntawv. frameshift thiab point mutation yog dab tsi? Ib qho kev hloov pauv cuam tshuam rau ib khub hauv paus.
Qhov kev hloov pauv no puas yuav ua rau muaj kev hloov pauv hloov pauv?
Yog li, yog tias muaj kev hloov pauv, piv txwv li, kev ntxig lossis tshem tawm ntawm nucleotide, tshwm sim, qhov no tuaj yeem ua rau kev hloov pauv ntawm kev nyeem ntawv. Nws hloov tag nrho cov amino acid ib ntus. Cov kev hloov pauv no yog hu ua frameshift mutation (tseem hu ua kev nyeem ntawv hloov pauv, nyeem ntawv hloov pauv, lossis framing yuam kev).
Puas yog jurassic ntiaj teb hloov pauv hloov pauv hloov pauv?
Qee zaum, paub meej, koj yuav tau rov qab mus rau lub sijhawm dhau los - txuag manually, thiab feem ntau, raws li game's autosave yog… tsis zam txim - tab sis feem ntau ntawm cov lub sijhawm koj tuaj yeem khaws cov khoom thiab khaws cia nrog.
Qhov twg yog qhov kev hloov pauv hloov pauv hloov pauv?
Semiconservative replication piav qhia txog cov txheej txheem ntawm DNA replication nyob rau hauv tag nrho cov paub hlwb. DNA replication tshwm sim ntawm ntau lub hauv paus pib ntawm kev rov ua dua raws DNA qauv strand. Raws li DNA ob chav helix yog unwound by helicase, replication tshwm sim nyias ntawm txhua tus qauv strand nyob rau hauv antiparallel cov lus qhia.
Qhov kev hloov pauv twg yog xav tias yuav cuam tshuam los ntawm kev hloov pauv hloov pauv?
Dependent Variable Qhov sib txawv uas nyob ntawm lwm yam uas ntsuas. Cov kev hloov pauv no yuav tsum tau hloov pauv raws li qhov kev sim ua haujlwm ntawm tus kheej hloov pauv lossis hloov pauv. Nws yog cov nyhuv presumed. Qhov kev tshawb fawb hloov pauv twg yog qhov tshwm sim?
