Hauv computer, kev teem sijhawm yog qhov ua haujlwm ntawm kev muab cov peev txheej los ua haujlwm. Cov peev txheej yuav yog processors, network txuas lossis nthuav daim npav. Cov dej num yuav yog xov, txheej txheem lossis cov ntaub ntawv ntws. Lub sijhawm teem caij ua haujlwm yog ua los ntawm tus txheej txheem hu ua tus teem sijhawm.
txhais tau li cas los ntawm kev teem sijhawm algorithm?
Definition: A Scheduling Algorithm yog algorithm uas qhia peb lub sijhawm CPU ntau npaum li cas peb tuaj yeem faib rau cov txheej txheem. … Los ntawm kev nyiam, thaum cov txheej txheem tseem ceeb tshaj plaws nkag mus, nws preempts cov txheej txheem tseem ceeb tsawg nyob nruab nrab thiab ua tiav cov txheej txheem tseem ceeb ua ntej.
Vim li cas thiaj siv sijhawm teem sijhawm algorithms?
Lub hom phiaj tseem ceeb ntawm kev teem sijhawm algorithms yog txhawm rau txo qis kev tshaib plab thiab kom muaj kev ncaj ncees ntawm cov tog neeg siv cov peev txheej Teem sijhawm cuam tshuam nrog cov teeb meem ntawm kev txiav txim siab qhov twg ntawm qhov kev thov zoo tshaj plaws yog los faib cov peev txheej. Muaj ntau ntau qhov sib txawv algorithms.
Leej twg ua sijhawm teem sijhawm?
Lub sijhawm luv lossis CPU teem sijhawm :Nws yog lub luag haujlwm xaiv ib txheej txheem los ntawm lub xeev npaj rau kev teem sijhawm rau lub xeev khiav. Nco tseg: Lub sijhawm luv luv tsuas yog xaiv cov txheej txheem los teem sijhawm nws tsis thauj cov txheej txheem ntawm kev khiav haujlwm. Nov yog thaum txhua qhov kev teem caij algorithms siv.
Lub sijhawm teem sijhawm twg yog qhov zoo tshaj?
Qee zaum FCFS algorithm zoo dua li lwm qhov hauv lub sijhawm luv luv thaum Round Robin zoo dua rau ntau cov txheej txheem hauv txhua lub sijhawm. Txawm li cas los xij, nws tsis tuaj yeem kwv yees tias txheej txheem yuav los tom qab. Lub Sijhawm Tos Nruab Nrab yog ib qho qauv ntsuas rau kev muab credit rau lub sijhawm teem sijhawm algorithm.
