Qhov Tseem Ceeb Qhov txawv - Tus neeg siv hom vs Kernel hom
Ib lub computer ua haujlwm hauv ob hom uas yog hom neeg siv thiab hom ntsiav. Thaum lub computer khiav daim ntawv thov software, nws yog nyob rau hauv hom neeg siv. Tom qab daim ntawv thov software thov rau kho vajtse, lub computer nkag mus rau hom ntsiav. Lub kernel yog lub hauv paus ntawm lub computer system. Tom qab ntawd, lub computer nquag hloov ntawm hom neeg siv thiab hom ntsiav. Feem ntau cov haujlwm tseem ceeb ntawm kev ua haujlwm yog ua haujlwm hauv hom ntsiav. Qhov sib txawv tseem ceeb ntawm Hom Neeg Siv thiab Kernel Hom yog cov neeg siv hom yog hom uas cov ntawv thov tau khiav thiab kernel hom yog hom tsim nyog uas lub khoos phis tawj nkag mus thaum nkag mus rau cov khoom siv kho vajtse.
Tus neeg siv hom yog dab tsi?
Thaum lub khoos phis tawj ua haujlwm, nws nyob hauv hom neeg siv. Qee qhov piv txwv yog lo lus thov, PowerPoint, nyeem cov ntawv PDF thiab tshawb hauv internet. Cov no yog cov kev pab cuam kom lub computer nyob rau hauv hom neeg siv. Thaum cov txheej txheem nyob rau hauv cov neeg siv hom thiab xav tau ib qho kev pab kho vajtse, qhov kev thov ntawd raug xa mus rau lub ntsiav. Raws li muaj kev txwv kev nkag mus rau cov khoom siv hauv hom no, nws paub tias yog hom tsis muaj cai tsawg, hom qhev lossis hom txwv.
Daim duab 02: Hom Kev Ua Haujlwm
Hauv hom neeg siv, cov txheej txheem tau txais lawv qhov chaw nyob thiab tsis tuaj yeem nkag mus rau qhov chaw nyob uas yog nyob rau hauv lub ntsiav. Yog li qhov ua tsis tiav ntawm ib txheej txheem yuav tsis cuam tshuam rau lub operating system. Yog tias muaj kev cuam tshuam, nws tsuas yog cuam tshuam rau cov txheej txheem tshwj xeeb.
Kernel hom yog dab tsi?
A kernel yog software program uas siv los nkag rau cov khoom siv kho vajtse ntawm lub khoos phis tawj. Kernel ua hauj lwm raws li ib tug nruab nrab software rau kho vajtse thiab daim ntawv thov software / neeg siv cov kev pab cuam. Kernel hom feem ntau yog tshwj tseg rau qib qis kev ntseeg siab ntawm lub operating system.
Thaum tus txheej txheem tab tom ua haujlwm hauv hom neeg siv thiab yog tias cov txheej txheem ntawd xav tau cov khoom siv kho vajtse xws li RAM, lub tshuab luam ntawv thiab lwm yam, cov txheej txheem yuav tsum xa daim ntawv thov mus rau kernel. Cov kev thov no raug xa los ntawm kev hu xov tooj. Tom qab ntawd lub computer nkag mus Kernel hom los ntawm hom neeg siv. Thaum ua haujlwm tiav, hom hloov rov qab mus rau cov neeg siv hom los ntawm hom ntsiav. Qhov kev hloov pauv no hu ua "context switching". Kernel hom tseem hu ua system hom lossis hom muaj cai. Nws tsis tuaj yeem khiav tag nrho cov txheej txheem hauv cov ntsiav hom vim tias yog cov txheej txheem tsis ua haujlwm tag nrho cov haujlwm yuav ua tsis tiav.
Daim duab 02: Kernel
Muaj ntau hom kev hu xov tooj. Cov txheej txheem tswj kev hu xov tooj tsim cov txheej txheem thiab txiav cov txheej txheem. Kev tswj cov ntaub ntawv hu tau nyeem, sau, tsim, rho tawm, qhib, thiab kaw cov ntaub ntawv. Cov cuab yeej tswj hwm lub kaw lus hu thov cov cuab yeej thiab tso tawm cov cuab yeej, tau txais thiab teeb tsa cov khoom siv. Tseem muaj cov ntaub ntawv saib xyuas kev hu xov tooj. Lawv tuaj yeem siv tau kom tau txais cov ntaub ntawv kaw lus, sijhawm, hnub tim. Cov peev txheej xav tau los ntawm ib txheej txheem tuaj yeem tuav los ntawm lwm tus txheej txheem. Yog li ntawd, cov txheej txheem yuav tsum sib txuas lus siv kev sib txuas lus hu xov tooj. Kev sib txuas lus hu tuaj yeem tsim thiab tshem tawm kev sib txuas, xa thiab txais cov ntaub ntawv xwm txheej.

| Hauv Hom Neeg Siv, yog tias muaj kev cuam tshuam tshwm sim, tsuas yog ib txheej txheem ua tsis tiav. | Hauv Kernel Hom, yog tias muaj kev cuam tshuam tshwm sim, tag nrho cov kev khiav hauj lwm yuav ua tsis tiav. |
| Txoj kev txwv | |
| Hauv hom neeg siv, muaj kev txwv rau kev nkag mus rau cov khoos phis tawj ntsiav. Nkag tsis tau ncaj qha rau lawv. | Nyob rau hauv hom ntsiav, ob qho tib si cov neeg siv cov kev pab cuam thiab kernel cov kev pab cuam tuaj yeem nkag mus tau. |
Summary – Tus neeg siv hom vs Kernel hom
Ib lub computer ua haujlwm hauv hom neeg siv lossis hom ntsiav. Qhov sib txawv ntawm Hom Neeg Siv thiab Kernel Hom yog cov neeg siv hom yog hom txwv uas cov ntawv thov tau ua haujlwm thiab hom ntsiav yog hom tsim nyog uas lub khoos phis tawj nkag mus thaum nkag mus rau cov khoom siv kho vajtse. Lub computer tab tom hloov ntawm ob hom no. Kev hloov cov ntsiab lus nquag tuaj yeem ua rau qeeb qeeb tab sis nws tsis tuaj yeem ua tiav tag nrho cov txheej txheem hauv hom ntsiav. Qhov ntawd yog vim; Yog tias ib txoj haujlwm ua tsis tiav tag nrho cov haujlwm yuav ua tsis tiav.
