I-UNIX kernel ngundoqo wendlela yokusebenza. Ibonelela ngokujongana nezixhobo zehardware kunye nokuqhubekeka, inkumbulo, kunye nolawulo lwe-I/O. I-kernel ilawula izicelo ezivela kubasebenzisi ngokusebenzisa iifowuni zenkqubo ezitshintsha inkqubo ukusuka kwindawo yomsebenzisi ukuya kwindawo ye-kernel (jonga uMzobo 1.1).
Yeyiphi imisebenzi ephambili yekernel?
I-kernel yenza imisebenzi yayo, njenge uqhuba iinkqubo, ulawulo lwezixhobo zehardware ezifana nehard diski, kunye nokuphathwa kokuphazamiseka, kule ndawo yekernel ekhuselweyo. Ngokwahlukileyo, iinkqubo zesicelo ezifana neziphequluli, iiprosesa zegama, okanye iaudio okanye abadlali bevidiyo basebenzisa indawo eyahlukileyo yememori, indawo yomsebenzisi.
Yeyiphi imisebenzi yekernel kwiLinux?
I-kernel inemisebenzi emi-4:
- Ulawulo lwememori: Gcina umkhondo wokuba ingakanani imemori esetyenziselwa ukugcina ntoni, kwaye phi.
- Ulawulo lwenkqubo: Qinisekisa ukuba zeziphi iinkqubo ezinokusebenzisa iyunithi yokucubungula ephakathi (CPU), nini, kwaye ixesha elingakanani.
- Abaqhubi besixhobo: Yenza njengomlamli/itoliki phakathi kwehardware kunye neenkqubo.
Yintoni i-kernel kunye nomsebenzi wayo?
I-Kernel inoxanduva lwemisebenzi ekumgangatho ophantsi njengolawulo lwediski, ulawulo lwememori, ulawulo lomsebenzi, njl inikeza ujongano phakathi komsebenzisi kunye namalungu ehardware yesixokelelwano. Xa inkqubo yenza isicelo kwi-Kernel, emva koko ibizwa ngokuba yi-System Call.
Zeziphi iimpawu zekernel?
Uphawu oluphambili kuyo nayiphi na inkqubo yokusebenza, i-kernel ilawula unxibelelwano phakathi kwehardware kunye nesoftware. I-kernel inoxanduva lokulawula imemori, kunye ne-I / O kwimemori, i-cache, i-hard drive, kunye nezinye izixhobo. Ikwajongana nemiqondiso yesixhobo, ukucwangciswa komsebenzi, kunye neminye imisebenzi ebalulekileyo.
Yintoni umsebenzi weUNIX?
I-UNIX yinkqubo yekhompyutha esebenzayo. Inkqubo yokusebenza yinkqubo elawula onke amanye amalungu enkqubo yekhompyutha, zombini ihardware kunye nesoftware. Yona yabe izibonelelo zekhompyutha kunye neeshedyuli imisebenzi. Ikuvumela ukuba usebenzise izixhobo ezibonelelwa yinkqubo.
Kutheni sifuna i-kernel?
Eyona njongo iphambili yekernel ukulawula unxibelelwano phakathi kwesoftware, oko kukuthi usetyenziso lwenqanaba lomsebenzisi kunye nehardware oko kukuthi, i-CPU kunye nememori yedisk. Iinjongo zeKernel : Ukuseka unxibelelwano phakathi kwenqanaba lomsebenzisi kunye nehardware. … Ukulawula ulawulo lwenkumbulo.
Ngowuphi owona msebenzi uphambili weLinux?
I-Linux® yinkqubo yokusebenza yomthombo ovulekileyo (OS). Inkqubo esebenzayo yisoftware ilawula ngokuthe ngqo ihardware yenkqubo kunye nezibonelelo, njenge-CPU, imemori, kunye nokugcinwa. I-OS ihlala phakathi kosetyenziso kunye nehardware kwaye yenza unxibelelwano phakathi kwayo yonke isoftware yakho kunye nezixhobo ezibonakalayo ezenza umsebenzi.
Yeyiphi ikernel esetyenziswa kwiLinux?
ILinux yiyo i-monolithic kernel ngelixa i-OS X (XNU) kunye ne-Windows 7 isebenzisa i-hybrid kernels.
Ngaba i-kernel yinkqubo?
I-kernel inkulu kunenkqubo. Idala kwaye ilawule iinkqubo. I-kernel sisiseko seNkqubo esebenzayo ukwenza kube lula ukusebenza ngeenkqubo.
Ngaba iWindows inayo ikernel?
Isebe leWindows NT leefestile linayo iHybrid Kernel. Ayiyiyo i-monolithic kernel apho zonke iinkonzo zisebenza kwimowudi yekernel okanye iMicro kernel apho yonke into isebenza kwindawo yomsebenzisi.
