Iyini imicu yezinga le-kernel?
Imicu yezinga le-Kernel iphathwa isistimu yokusebenza ngokuqondile futhi ukuphathwa kwentambo kwenziwa yi-kernel. Ulwazi lomongo wenqubo kanye nemicu yenqubo konke kulawulwa yi-kernel. Ngenxa yalokhu, imicu yeleveli ye-kernel ihamba kancane kunemicu yeleveli yomsebenzisi.
Iyini inqubo ye-kernel?
Inqubo ye-kernel ilawula ngokuqondile imicu ye-kernel. Ngenxa yokuthi izinqubo ze-kernel zihlala zikusizinda sokuvikela i-kernel, imicu engaphakathi kwenqubo ye-kernel iyintambo ye-kernel kuphela. … Inqubo ye-kernel ayinalo uhla lwemibhalo lwempande noma uhla lwemibhalo lwamanje lapho luqaliswa.
Uma kwakhiwa imicu ukuthi imisebenzi ye-kernel ibizwa kanjani?
Kujwayelekile ukuthi ikhodi ye-kernel yakhe izinqubo ezingasindi - imicu ye-kernel - eyenza umsebenzi othile ngokulinganayo. … int thread_function(engenalutho *idatha); Umsebenzi uzobizwa ngokuphindaphindiwe (uma kudingeka) ngekhodi ye-kthread; ingakwazi ukwenza noma yimuphi umsebenzi eklanyelwe ukuba iwenze, ilale lapho kudingekile.
Uyini umehluko phakathi kwemicu yabasebenzisi nemicu ye-kernel?
Imicu yezinga lomsebenzisi iyashesha ukuyidala nokuphatha. Imicu yeleveli ye-Kernel iyanensa ukudala nokuphatha. Ukuqaliswa kwenziwa ngomtapo wolwazi osezingeni lomsebenzisi. … Uchungechunge lwezinga lomsebenzisi lujwayelekile futhi lungasebenza kunoma iyiphi isistimu yokusebenza.
Uyini umehluko phakathi kwe-kernel ne-OS?
Umehluko oyisisekelo phakathi kwesistimu yokusebenza ne-kernel ukuthi uhlelo lokusebenza luwuhlelo lwesistimu olulawula izinsiza zesistimu, futhi i-kernel iyingxenye ebalulekile (uhlelo) ohlelweni lokusebenza. … Ngakolunye uhlangothi, i-Opertaing System isebenza njengesixhumi esibonakalayo phakathi komsebenzisi nekhompyutha.
Buyini ubudlelwano phakathi kwentambo ye-kernel nentambo yomsebenzisi?
Amamodeli Wokufunda okuningi
Nokho, ukusekela imicu kungase kuhlinzekwe ezingeni lomsebenzisi, izintambo zomsebenzisi, noma i-kernel, emicu ye-kernel. Imicu yabasebenzisi isekelwa ngaphezu kwe-kernel futhi iphathwa ngaphandle kokusekelwa kwe-kernel, kuyilapho imicu ye-kernel isekelwa futhi iphathwa ngokuqondile isistimu yokusebenza.
