Hauv kev tshawb fawb hauv computer, microkernel (feem ntau hu ua Μ-kernel) yog qhov ze-tsawg kawg ntawm software uas tuaj yeem muab cov txheej txheem xav tau los siv lub operating system (OS). Cov txheej txheem no suav nrog kev tswj hwm qhov chaw nyob qis qis, kev tswj cov xov, thiab kev sib tshuam kev sib txuas lus (IPC).
Ua li no, siv microkernel nyob qhov twg?
Microkernels tau nrov nyob rau hauv 1980s vim hais tias ntawm lub cim xeeb thiab cia txwv ntawm lub computer thaum ntxov. Thaum lawv tseem nyob siv rau qee tus neeg rau zaub mov OSes, feem ntau cov kev khiav hauj lwm loj, xws li Windows thiab OS X, siv monolithic kernels.
Tsis tas li ntawd, Windows puas siv microkernel? Tsis yog yog ib hybrid kernel. Ib hybrid kernel yog kev sib haum xeeb ntawm ib tug monolithic kernel thiab a microkernel , thiab muaj qee yam ntawm ob qho tib si.
Ntawm no, microkernel system qauv yog dab tsi?
Microkernel yog software lossis code uas muaj qhov tsawg kawg nkaus ntawm kev ua haujlwm, cov ntaub ntawv, thiab cov yam ntxwv los siv kev khiav haujlwm qhov system . Nws muab cov txheej txheem tsawg tsawg, uas yog qhov zoo txaus los khiav cov haujlwm yooj yim tshaj plaws ntawm kev ua haujlwm qhov system.
Qhov txawv ntawm microkernel thiab microkernel yog dab tsi?
Micro kernel yog a ntsiav uas khiav cov kev pab cuam uas tsawg heev rau kev khiav hauj lwm qhov system. Hauv no ntsiav Tag nrho lwm cov haujlwm yog ua los ntawm processor. Macro Kernel yog kev sib txuas ntawm micro thiab monolithic kernel . Hauv monolithic kernel tag nrho cov operating system code yog nyob rau hauv ib daim duab executable.
