Hauv cov ntsiab lus yooj yim, abstraction " tso tawm" tsuas yog cov yam ntxwv cuam tshuam ntawm cov khoom thiab " nkaum" cov ntsiab lus tsis tsim nyog. Piv txwv li, thaum peb tsav tsheb, peb tsuas yog txhawj xeeb txog kev tsav tsheb xws li pib / nres lub tsheb, nrawm / tawg, thiab lwm yam … Qhov no yog ib qho piv txwv yooj yim ntawm abstraction.
Yuav ua li cas piv txwv zoo ntawm abstraction?
Koj lub tsheb yog qhov piv txwv zoo ntawm kev paub daws teeb meem. Koj tuaj yeem pib lub tsheb los ntawm tig tus yuam sij lossis nias lub pob pib. Koj tsis tas yuav paub tias lub cav pib li cas, txhua yam khoom koj lub tsheb muaj dab tsi. Lub tsheb sab hauv kev siv thiab cov logic nyuaj yog zais tag nrho los ntawm tus neeg siv.
Dab tsi yog lub neej piv txwv ntawm abstraction?
Lwm lub neej tiag tiag piv txwv ntawm Abstraction yog ATM Tshuab; Txhua yam ua haujlwm ntawm lub tshuab ATM xws li rho nyiaj ntsuab, hloov nyiaj, khaws cov lus qhia me me… thiab lwm yam. tab sis peb tsis tuaj yeem paub cov ntsiab lus sab hauv ntawm ATM. Nco tseg: Cov ntaub ntawv abstraction tuaj yeem siv los muab kev ruaj ntseg rau cov ntaub ntawv los ntawm txoj kev tsis tau tso cai.
Ib qho piv txwv ntawm abstraction hauv computer science yog dab tsi?
Cov lus hauv computer tuaj yeem ua tiav nrog lub computer. Ib qho piv txwv ntawm cov txheej txheem abstraction no yog kev txhim kho ntawm cov lus programming los ntawm cov lus tshuab mus rau cov lus sib dhos thiab cov lus qib siab Txhua theem tuaj yeem siv los ua lub pob zeb rau theem tom ntej.
Puas yog chav kawm ib qho piv txwv ntawm abstraction?
Abstraction yog lub tswvyim dav dav uas koj tuaj yeem pom hauv lub ntiaj teb tiag thiab hauv OOP hom lus. Txhua yam khoom hauv ntiaj teb tiag tiag, zoo li koj lub tshuab kas fes, lossis cov chav kawm hauv koj qhov haujlwm software tam sim no, uas zais cov ntsiab lus sab hauv muab qhov kev xav tsis thoob.

Ib qho piv txwv ntawm kev ua piv txwv yog dab tsi?
Raws li qhov piv txwv ntawm kev ua qauv zoo, xav tias hauv cov pejxeem ntawm 10,000 tus neeg, tus kws txheeb cais xaiv txhua 100 tus neeg rau kev kuaj. Cov sijhawm piv txwv kuj tseem tuaj yeem ua tau zoo, xws li xaiv tus qauv tshiab los kos los ntawm txhua 12 teev .
Puas yog piv txwv ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov khoom siv hluav taws xob?
Piv txwv rau cov khoom siv tsis ncaj band sib txawv yog silicon (Si), germanium (Ge), aluminium arsenide (AlAs) thiab gallium phosphide (GaP) . Yuav ua li cas piv txwv ntawm indirect band gap? Piv txwv ntawm cov ntaub ntawv ncaj qha muaj xws li amorphous silicon thiab qee cov khoom siv III-V xws li InAs thiab GaAs.
Puas yog piv txwv ntawm kev piv txwv?
Piv txwv ntawm kev tuag metaphors tuag metaphors Ib qho piv txwv tuag yog ib daim duab ntawm kev hais lus uas tau ploj qhov qub duab ntawm nws lub ntsiab lus los ntawm kev siv dav, rov ua dua, thiab siv nrov. Cov lus piv txwv tuag feem ntau yog qhov tshwm sim ntawm kev hloov pauv hauv kev hloov pauv hauv kev hloov pauv ntawm ib hom lus, txheej txheem hu ua kev hais lus ntawm kev ua piv txwv.
Qhov twg yog qhov piv txwv ntawm kev sib piv?
Adjectives nyob rau hauv daim ntawv sib piv piv ob tug neeg, qhov chaw, los yog yam. Piv txwv li, nyob rau hauv kab lus, 'John yog smarter, tab sis Bob siab dua, ' cov ntaub ntawv sib piv ntawm cov npe 'smart' (smarter) thiab 'siab' (siab) yog siv los ua.
Puas yog cov qauv piv txwv zoo ib yam li kev ua piv txwv?
Lub hom phiaj sampling yog siv dav hauv kev tshawb fawb zoo rau kev txheeb xyuas thiab xaiv cov ntaub ntawv nplua nuj cuam tshuam txog qhov tshwm sim ntawm kev txaus siab. Txawm hais tias muaj ntau ntau lub hom phiaj ua piv txwv, cov qauv qauv zoo li tau siv feem ntau hauv kev tshawb fawb siv.
