I-abstraction yi-software efihla iinkcukacha ezisezantsi kwaye ibonelele ngeseti yemisebenzi yomgangatho ophezulu. Inkqubo yokusebenza iguqula ilizwe elibonakalayo lezixhobo, imiyalelo, inkumbulo, kunye nexesha libe lihlabathi lenyani elisisiphumo sezinto ezithathwayo ezakhiwe yinkqubo yokusebenza.
Yintoni injongo yomaleko wokuthabatha?
Kwi-computing, i-abstraction layer okanye i-abstraction level yindlela yokufihla iinkcukacha zokusebenza ze-subsystem, evumela ukuhlukana kweenkxalabo ukuququzelela ukusebenzisana kunye nokuzimela kweqonga.
Zeziphi iingenelo zeenkqubo zokusebenza ezibonelela nge-abstraction?
I-operating system abstraction layer (OSAL) ibonelela ngojongano lwenkqubo yesicelo (API) kwi-abstract operating system eyenza kube lula kwaye kukhawuleze ukuphuhlisa ikhowudi yesoftware okanye iiplatifti zehardware.
Yintoni inkqubo abstraction kwinkqubo yokusebenza?
Iinkqubo zezona zisithintelo esisisiseko senkqubo yokusebenza. Iinkqubo ziququzelela ulwazi malunga nezinye izinto ezithathayo kwaye zimele into enye "eyenzayo" yikhompyuter. Uyazazi iinkqubo njenge-app(uncedo)s.
Yeyiphi kwezi zilandelayo engabonakaliyo yinkqubo yokusebenza?
Ukukhutshwa kwehardware
Umsebenzi osisiseko wenkqubo yokusebenza (OS) kukutsala ihardware kumdwelisi wenkqubo nakumsebenzisi. Isixokelelwano esisebenzayo sibonelela ngojongano oluqhelekileyo kwiinkonzo ezibonelelwa yihardware engaphantsi.
Zeziphi iintlobo zokuthabatha?
Zintathu iindidi ze-abstract: echazayo, efundisayo kunye negxekayo. Iimpawu ze-abstract ezilungileyo ziyajongwa kwaye ezinye zeempazamo eziqhelekileyo zinikwe.
Uthetha ukuthini ngokuthabatha?
I-abstraction yinto eqhelekileyo okanye ingcamango, kunokuba into ephathekayo okanye ephathekayo. Kwisayensi yekhompyuter, i-abstraction inenkcazo efanayo. Luguqulelo olulula lwento yobugcisa, njengomsebenzi okanye into ekwinkqubo.
Yeyiphi enoxanduva lokugcina yonke into ebalulekileyo yokutsalwa kwenkqubo yokusebenza?
I-kernel inoxanduva lokugcina izinto ezibalulekileyo zenkqubo yokusebenza. -Ikhowudi yeKernel isebenza kwimowudi yekernel ngokufikelela ngokupheleleyo kuzo zonke izixhobo ezibonakalayo zekhompyuter. -Yonke ikhowudi ye-kernel kunye nezakhiwo zedatha zigcinwa kwindawo enye yedilesi enye.
Ngaba inkumbulo itsalwa yinkqubo yokusebenza?
Ukufihla iinkcukacha zehardware ngokwenza i-abstraction
Inkqubo yokusebenza iguqula ilizwe elibonakalayo lezixhobo, imiyalelo, inkumbulo, kunye nexesha libe lihlabathi lenyani elisisiphumo sezinto ezithathwayo ezakhiwe yinkqubo yokusebenza. Kukho izizathu ezininzi zokuthatha.
Ngaba i-hardware itsalwa yi-OS?
Ukukhutshwa kwe-Hardware kaninzi kuvumela abadwelisi beprogram ukuba babhale izixhobo ezizimeleyo, izicelo zokusebenza eziphezulu ngokubonelela ngenkqubo yokusebenza esemgangathweni (i-OS) iminxeba kwi-hardware. … Inkqubo yokutsala amaqhekeza ehardware ikholisa ukwenziwa ngokwembono ye-CPU.
Yintoni inkqubo yoluhlu lwenkqubo yokusebenza?
Inkqubo yeHierarchy
Xa inkqubo idala enye inkqubo, ngoko inkqubo yomzali nomntwana badla ngokunxulumana ngeendlela ezithile nangakumbi. Inkqubo yomntwana inokudala ezinye iinkqubo ukuba ziyafuneka. Olu lwakhiwo lomzali-omntwana olufana nolwakhiwo lweenkqubo lwenza uluhlu lwemigangatho, olubizwa ngokuba yiProcess Hierarchy.
Yintoni umahluko phakathi kokutsalwa kwenkqubo kunye nokutsalwa kwedatha?
Impendulo: Ukutsalwa kwenkqubo kuqheleke kuphawulwe kulwimi lwenkqubo njengokuthi “umsebenzi/umsebenzi ongaphantsi” okanye “inkqubo” yokuthatha. Ukutsalwa kwedatha: ... Kolu hlobo lokuthatha, endaweni yokugxila kwimisebenzi, sigxila kwidatha kuqala kwaye emva koko imisebenzi ekhohlisa idatha.
Yintoni ukutsalwa kwenkqubo kunye nokutsalwa kwedatha?
Ngokwesiko, ukutsalwa kwedatha kunye nokutsalwa okusebenzayo kudityaniswa kwingqikelelo yeentlobo zedatha ye-abstract (ADT). Ukudibanisa i-ADT kunye nelifa kunika izinto ezingundoqo ze-paradigm esekelwe kwinto. Kwi-abstraction yenkqubo, iinkcukacha zemisonto yokubulawa azibonakali kumthengi wenkqubo.
Yintoni indima yomsebenzisi kwinkqubo yokusebenza?
Owona msebenzi ucacileyo womsebenzisi kukwenziwa kweenkqubo. Uninzi lweenkqubo zokusebenza zikwavumela umsebenzisi ukuba achaze enye okanye ii-operands ezininzi ezinokugqithiselwa kwinkqubo njengeengxoxo. Imisebenzi inokuba ligama leefayile zedatha, okanye inokuba ziiparamitha eziguqula indlela yokuziphatha kwenkqubo. okanye ifayile yedatha.
Ithetha ntoni inkqubo kwi-computing?
