Txheej txheem synchronization txhais tau tias sib koom qhov system cov peev txheej los ntawm txheej txheem nyob rau hauv ib txoj kev uas, Concurrent nkag mus rau cov ntaub ntawv sib koom yog ua li no minimizing lub sij hawm ntawm inconsistent cov ntaub ntawv. Kev tuav cov ntaub ntawv sib xws xav tau cov txheej txheem los xyuas kom meej synchronized kev ua haujlwm ntawm kev sib koom tes txheej txheem.
Kuj paub, hom txheej txheem synchronization yog dab tsi?
Taw qhia ntawm Txheej txheem Synchronization . Nyob rau hauv lub hauv paus ntawm synchronization , txheej txheem raug categorized ua ib qho ntawm ob qho hauv qab no hom : Kev ywj pheej Txheej txheem : Execution of ib txheej txheem tsis cuam tshuam rau kev ua hauj lwm txheej txheem . Kev koom tes Txheej txheem : Execution of ib txheej txheem cuam tshuam rau kev ua hauj lwm txheej txheem
Tsis tas li ntawd, dab tsi yog qhov tseem ceeb hauv kev ua haujlwm? Cov Nqe lus tseem ceeb Teeb meem Nqe lus tseem ceeb yog ib feem ntawm qhov kev pab cuam uas sim nkag mus rau cov peev txheej sib koom. Cov ntu tseem ceeb tsis tuaj yeem ua tiav los ntawm ntau tshaj ib txoj haujlwm tib lub sijhawm; kev khiav hauj lwm qhov system ntsib cov teeb meem hauv kev tso cai thiab tsis tso cai rau cov txheej txheem nkag mus rau hauv ntu tseem ceeb.
Koj txhais li cas los ntawm Process synchronization Vim li cas nws yuav tsum tau?
Cov txheej txheem synchronization xav tau yuav tsum tau siv los tiv thaiv cov ntaub ntawv inconsistency ntawm txheej txheem , txheej txheem deadlocks, thiab tiv thaiv haiv neeg tej yam kev mob, uas yog thaum ua haujlwm ob lossis ntau dua yog raug tua nyob rau tib lub sijhawm, tsis tau teem sijhawm nyob rau hauv raws li qhov tsim nyog thiab tsis tawm hauv qhov tseem ceeb kom raug.
Vim li cas thiaj xav tau synchronization?
Synchronization yog qhov tseem ceeb vim nws tshawb xyuas qhov sib txawv ntawm ob lub thawv cov ntaub ntawv txhawm rau zam qhov tsis xav tau hloov pauv ntawm cov ntaub ntawv uas twb nyob hauv ob qhov chaw cov ntaub ntawv. Yog li ntawd, synchronization schemes feem ntau hloov kho ob qho tib si cov ntaub ntawv los ntawm kev hloov pauv tsuas yog ntxiv, hloov pauv, thiab tshem tawm.

Dab tsi yog qhov tsis zoo ntawm cov txheej txheem txheej txheem?
Ib qho tsis zoo ntawm kev siv Procedural Programming raws li ib txoj hauv kev programming yog qhov tsis muaj peev xwm rov siv tau cov lej thoob plaws hauv qhov program. Yuav tsum rov sau tib hom code ntau zaus thoob plaws ib qho kev pab cuam tuaj yeem ntxiv rau tus nqi tsim kho thiab lub sijhawm ntawm qhov project. Lwm qhov tsis zoo yog qhov nyuaj ntawm kev kuaj xyuas yuam kev
Yuav ua li cas yog ib tug txheej txheem nyob rau hauv lub operating system dab tsi yog ib tug xov nyob rau hauv lub operating system?
Ib tug txheej txheem, nyob rau hauv cov nqe lus yooj yim tshaj, yog ib tug executingprogram. Ib tug los yog ntau tshaj threads khiav nyob rau hauv cov ntsiab lus ntawm cov txheej txheem. Ib tug xov yog ib qho tseem ceeb chav tsev uas theoperating system faib lub sij hawm processor. Lub threadpool feem ntau yog siv los txo tus naj npawb ntawm cov ntaub ntawv thov thiab muab kev tswj hwm ntawm cov neeg ua haujlwm threads
Dab tsi yog qhov haujlwm ntawm OSI txheej txheej txheej txheej txheej txheem router ua haujlwm li cas?
Hauv Cov Qauv Qhib Kev Sib Txuas Sib Txuas (OSI) kev sib txuas lus, txheej txheej txheej txheem nyob ntawm Txheej 5 thiab tswj kev teeb tsa thiab rhuav tshem ntawm kev sib txuas ntawm ob qhov kev sib txuas lus kawg. Kev sib txuas lus ntawm ob qhov kawg yog hu ua kev sib txuas
Lub luag haujlwm ntawm ntu tseem ceeb hauv cov txheej txheem synchronization yog dab tsi?
Ib qho kev daws teeb meem nrov heev rau cov txheej txheem synchronization yog qhov kev siv ntawm ntu tseem ceeb, uas yog ib ntu ntawm cov cai uas tuaj yeem nkag tau los ntawm tsuas yog ib qho txheej txheem teeb liab ntawm qee qhov piv txwv hauv lub sijhawm. Cov ntu tseem ceeb yog ib feem ntawm cov lej uas cov txheej txheem sib qhia cov ntaub ntawv raug tswj los ntawm kev siv semaphores
Dab tsi ntawm cov hauv qab no yog cov txheej txheem kev tshuaj xyuas cov ntaub ntawv hauv kev tshawb fawb zoo?
Cov txheej txheem kev txheeb xyuas cov ntaub ntawv feem ntau siv yog: Kev tsom xam cov ntsiab lus: Qhov no yog ib txoj hauv kev zoo tshaj plaws los tshuaj xyuas cov ntaub ntawv zoo. Kev txheeb xyuas cov lus piav qhia: Txoj kev no yog siv los txheeb xyuas cov ntsiab lus los ntawm ntau qhov chaw, xws li kev xam phaj ntawm cov neeg teb, kev soj ntsuam los ntawm thaj chaw, lossis kev tshawb fawb
