AP Computer Science Cov ntsiab lus hauv chav kawm
Abstraction : Abstraction txo cov ntaub ntawv thiab nthuav dav kom yooj yim rau kev tsom mus rau cov ntsiab lus tseem ceeb. Nws yog ib qho txheej txheem, lub tswv yim, thiab qhov tshwm sim ntawm kev txo cov ntsiab lus kom pom cov ntsiab lus cuam tshuam rau kev nkag siab thiab daws teeb meem
Hais txog qhov no, dab tsi yog abstraction hauv computer science piv txwv?
Ib piv txwv ntawm no abstraction txheej txheem yog lub generational kev loj hlob ntawm programming hom lus los ntawm tshuab lus mus rau cov lus sib dhos thiab cov lus siab. Hauv cov ntsiab lus yooj yim, abstraction yog tshem tawm cov ntaub ntawv tsis cuam tshuam ces ib qho kev pab cuam yooj yim to taub.
Ib sab saum toj, nws yog dab tsi abstraction? Nyob rau hauv object-oriented programming, abstraction yog ib qho ntawm peb lub hauv paus ntsiab lus (nrog rau encapsulation thiab qub txeeg qub teg). Los ntawm cov txheej txheem ntawm abstraction , tus programmer zais tag nrho tab sis cov ntaub ntawv cuam tshuam txog ib yam khoom txhawm rau txo qhov nyuaj thiab nce kev ua haujlwm.
Tsuas yog li ntawd, abstraction siv hauv computer science li cas?
Hauv software engineering thiab computer science , abstraction yog ib tug txheej txheem rau teem complexity ntawm lub computer tshuab. Nws ua haujlwm los ntawm kev tsim ib theem ntawm qhov nyuaj uas ib tus neeg cuam tshuam nrog lub kaw lus, txwv tsis pub cov ntsiab lus nyuaj dua hauv qab qib tam sim no.
Dab tsi yog abstraction thiab piv txwv?
npe. Lub ntsiab txhais ntawm abstraction yog ib lub tswv yim uas tsis muaj qhov xwm txheej, lossis yog qhov zoo tshaj plaws hauv qhov xwm txheej. Piv txwv ntawm abstractions tuaj yeem yog kev xav xws li kev tu siab lossis kev zoo siab. Abstraction txhais tau tias yog ib txoj hauj lwm ntawm kos duab uas cov ntsiab lus los yog cov ntsiab lus yog implied.

Dab tsi yog embedded systems hauv computer science?
Ib qho embedded system yog ib qho kev sib txuas ntawm lub khoos phis tawj kho vajtse thiab software, yog qhov ruaj khov hauv kev muaj peev xwm lossis programmable, tsim los rau kev ua haujlwm tshwj xeeb lossis kev ua haujlwm hauv lub cev loj dua
Dab tsi yog qhov program hauv computer science?
Lub khoos phis tawj yog ib phau ntawm cov lus qhia uas tuaj yeem ua tiav los ntawm lub khoos phis tawj los ua haujlwm tshwj xeeb. Feem ntau cov khoom siv hauv computer xav tau cov kev pab cuam kom ua haujlwm zoo. Ib qho khoos phis tawj feem ntau yog sau los ntawm computer programmer hauv hom lus programming
Koj kawm dab tsi hauv computer science cov hauv paus ntsiab lus?
Cov tub ntxhais kawm txhim kho lawv txoj kev nkag siab ntawm computer science los ntawm kev ua haujlwm nrog cov ntaub ntawv, sib koom tes los daws cov teeb meem, thiab tsim cov khoos phis tawj thaum lawv tshawb txog cov tswv yim xws li kev muaj tswv yim, kev paub daws teeb meem, cov ntaub ntawv thiab cov ntaub ntawv, algorithms, programming, internet, thiab kev cuam tshuam thoob ntiaj teb ntawm kev suav
Dab tsi yog code hauv computer science?
1) Hauv programming, code (noun) yog ib lo lus siv rau ob nqe lus sau ua ib hom lus programming - lub hauv paus code, thiab ib lo lus rau lub hauv paus code tom qab nws tau ua tiav los ntawm ib tug compiler thiab npaj txhij mus khiav hauv lub computer - cov khoom code
Dab tsi yog abstraction siv hauv computer science?
Abstraction yog qhov ua piv txwv ntawm cov yam ntxwv tseem ceeb yam tsis suav nrog cov ntsiab lus keeb kwm yav dhau los lossis kev piav qhia. Nyob rau hauv lub computer science thiab software engineering domain, lub ntsiab lus abstraction yog siv los txo cov complexity thiab tso cai rau tsim kom zoo thiab kev siv ntawm complex software systems
