Lub hom phiaj ntawm kev encoding yog hloov cov ntaub ntawv kom nws tuaj yeem ua tau zoo (thiab nyab xeeb) noj los ntawm ntau hom kab ke, piv txwv li. binary cov ntaub ntawv raug xa hauv email, lossis saib cov cim tshwj xeeb ntawm nplooj ntawv web. Lub hom phiaj tsis yog khaws cov ntaub ntawv zais cia, tab sis ua kom ntseeg tau tias nws tuaj yeem siv tau zoo.
Vim li cas peb thiaj encode cov ntaub ntawv?
Txij li thaum encoding tshem tawm cov ntaub ntawv rov qab los ntawm cov ntaub ntawv, qhov loj ntawm koj cov ntaub ntawv yuav tsawg dua. Qhov no ua rau kev nkag mus nrawm dua thaum cov ntaub ntawv raug cawm. Txij li cov ntaub ntawv encoded me me, koj yuav tsum tau txuag chaw ntawm koj cov khoom siv cia. Qhov no yog qhov zoo tshaj yog tias koj muaj ntau cov ntaub ntawv uas yuav tsum tau khaws cia.
Kev siv cov ntaub ntawv encoding yog dab tsi?
Computers siv encoding schemes khaws thiab khaws cov ntaub ntawv tseem ceeb raws li cov ntaub ntawv Qhov no yog hu ua cov ntaub ntawv encoding. Ntawm cov khoom siv hluav taws xob xws li khoos phis tawj, cov ntaub ntawv encoding muaj qee cov txheej txheem coding uas tsuas yog cov qauv hluav taws xob uas sawv cev rau txhua daim ntaub ntawv khaws cia thiab khaws cia.
Vim li cas tus encoder tseem ceeb?
Encoders yog siv rau hauv cov khoom siv uas yuav tsum tau ua haujlwm hauv kev kub ceev thiab muaj qhov raug siab. Tus txheej txheem ntawm kev tswj lub cev muaj zog tig los ntawm kev kuaj xyuas lub cev muaj zog kev sib hloov ceev thiab lub kaum sab xis uas siv lub encoder hu ua kev tawm tswv yim tswj (kaw lub voj voog txoj kev).
txhais tau li cas los ntawm cov ntaub ntawv encoded?
Encoding yog tus txheej txheem ntawm kev hloov cov ntaub ntawv mus rau hauv hom xav tau rau ntau cov ntaub ntawv xav tau, suav nrog: … Cov ntaub ntawv xa mus, khaws cia thiab compression / decompression. Daim ntawv thov cov ntaub ntawv ua, xws li cov ntaub ntawv hloov dua siab tshiab.
