Lwm txoj kev daws teeb meem rau sab nraud fragmentation yog tso cai qhov chaw nyob qhov chaw ntawm cov txheej txheem kom tsis sib thooj. Cov txheej txheem yog faib nrog lub cev muaj peev xwm nco thiab thaum twg tom qab muaj, nws raug xa mus rau txheej txheem.
Dab tsi yog teeb meem ntawm kev tawg ntawm sab nraud?
Kev tawg sab nraud tshwm sim thaum lub cim xeeb pub dawb tau muab cais ua cov blocks me me thiab cuam tshuam los ntawm kev faib cov cim xeebNws yog qhov tsis muaj zog ntawm qee qhov kev faib cov algorithms, thaum lawv tsis yuam kev nco siv los ntawm cov kev pab cuam zoo. … Muab peb lub block A, B, thiab C, loj 0x1000.
Yuav ua li cas compaction daws teeb meem ntawm sab nraud fragmentation?
Peb tseem tuaj yeem siv compaction kom txo qis qhov tshwm sim ntawm sab nraud fragmentation. Nyob rau hauv compaction, tag nrho cov dawb partitions yog ua contiguous thiab tag nrho cov loaded partitions yog coj los ua ke. Los ntawm kev siv cov txheej txheem no, peb tuaj yeem khaws cov txheej txheem loj dua hauv lub cim xeeb.
Koj daws qhov teeb meem fragmentation li cas siv nplooj ntawv?
Paging pab nrog kev sib cais sab nraud ntawm ob txoj hauv kev
- Ua ntej, nws faib lub cim xeeb rau hauv qhov loj me uas nyob ib sab chunks - nplooj ntawv - uas yog "loj txaus" yog li lawv yeej tsis muaj txiaj ntsig. …
- Thib ob, cov khoom siv paging muab ib theem ntawm kev taw qhia ntawm nplooj ntawv thov thiab nplooj ntawv lub cev nco.
Yuav ua li cas algorithms raug kev txom nyem los ntawm cov teeb meem ntawm sab nraud fragmentation?
Segmentation tuaj yeem ua rau muaj kev sib cais sab nraud, thaum tag nrho cov blocks ntawm lub cim xeeb dawb me dhau los ua kom haum rau ib ntu tab sis cov lej ntawm qhov chaw dawb yog loj dua li ntu. Yog li ntawd, paging raug kev txom nyem los ntawm kev tawg ntawm sab hauv thiab segmentation raug kev txom nyem los ntawm sab nraud fragmentation teeb meem.

Kev daws teeb meem puas yog txoj cai?
Kev daws tsis yog kev cai; lawv txawv hauv paus hauv lawv lub hom phiaj. Txawm li cas los xij, nyob rau qee qhov xwm txheej kev daws teeb meem tuaj yeem muaj txiaj ntsig ntawm txoj cai. Hauv txhua lub koom haum tsim cai, cov txheej txheem ua rau muaj kev daws teeb meem pib nrog tus tsim cai lij choj ua cov lus pom zoo hu ua tsab ntawv tsa suab .

Nws yog qhov zoo thiab tso cai, chav kawm paub daws teeb meem muaj tsawg kawg yog ib tus tswv cuab (txoj kev / khoom vaj khoom tsev) tsis siv kom nws tsis tuaj yeem ua sai sai .
Puas yog plaub txoj kev flashers teeb meem teeb meem?
Txhua lub tsheb tuaj nrog teeb ceeb toom teeb meem raws li cov khoom siv txheem. Kuj tseem hu ua "kev phom sij," "kev kub ceev blinkers" lossis "four-way flashers," cov teeb no pab koj cov neeg tsav tsheb pom koj thaum muaj ib yam dab tsi tsis ncaj ncees lawm ntawm koj lub tsheb, lossis thaum koj yuav tsum nres tsis tau xav txog.
