Lub logic ib feem ntawm daim ntawv thov los yog software yog tswj los ntawm programming . Programming tuaj yeem ua tiav siv ntau yam thev naus laus zis thiab hom lus. Tus neeg sau yam twg qhov kev pab cuam feem ntau yog hu ua a Programmer . Kev txhim kho lub vev xaib , ntawm qhov tod tes, yog txwv rau web apps (uas khiav hauv browser).
Xav txog qhov no, qhov txawv ntawm Web development thiab programming yog dab tsi?
Programming los yog kev loj hlob ntawm qhov tod tes yog ntsig txog coding . Web developers sau nplooj ntawv siv HTML thiab CSS; nruj me ntsis hais lawv tsis yog programming lus, so a web tus kws tsim txuj ci hauv HTML thiab CSS tuaj yeem tsim qhov zoo li qub lub vev xaib ,lub a lub vev xaib nrog qee qhov kev sib tham pem hauv ntej-kawg, xws li cov ntawv qhia zaub mov.
Ib yam li ntawd, qhov twg yog qhov zoo dua Web development lossis software txhim kho? A web developer yog a software engineer leej twg tsim web daim ntawv thov. “ Software Engineers" tsis muaj ib tug zoo dua nyiaj hli tshaj " Web Developers , "tsis ua" Software Engineers" ua haujlwm txawv dua li " WebDevelopers ” nyob rau hauv ib hnub-rau-hnub, piv txwv tias lawv tab tom ua haujlwm web daim ntawv thov.
Ntxiv mus, yog coding yuav tsum tau rau kev txhim kho Web?
Web designers yuav tsum tsis tsuas paub yuav ua li cas tsim cov ntsiab lus pom tab sis kuj muaj qhov tsim nyog code kev txawj ntse nyob rau hauv pem hauv ntej kawg kev loj hlob . Txawm tias programming koj tus kheej code lub tsev tsis yog tsim nyog , kev nkag siab yooj yim ntawm kev ua haujlwm ntawm HTML, CSS thiab JavaScript yog qhov tseem ceeb.
Puas yog Web txhim kho yooj yim dua li programming?
Kev txhim kho lub vev xaib feem ntau xav tias yooj yim tab sis qhov ntawd feem ntau yog qhov ua ntej-kawg. Lub back-endpart tuaj yeem dhau los ua qhov nyuaj heev nyob ntawm seb hom phiaj xwm koj tab tom tsim.

Dab tsi yog qhov txawv ntawm qhov Web Web thiab Deep Web?
Qhov sib txawv tseem ceeb yog qhov SurfaceWeb tuaj yeem ntsuas tau, tab sis Deep Web tsis tuaj yeem.Websites koj tsuas tuaj yeem nkag tau nrog tus neeg siv lub npe thiab tus password, xws li email thiab huab kev pabcuam nyiaj, chaw txhab nyiaj, thiab txawm tias kev tso npe hauv online tshaj tawm txwv los ntawm paywalls.Companies ' internal networks thiab ntau yam databases
Dab tsi yog qhov sib txawv ntawm lub thawv thiab lub thawv ntawv thiab lub thawv ntawv yog dab tsi?
Ib lub thawv thiab cov ntawv nplawm (qee zaum hu ua boxplot) yog ib daim duab uas nthuav tawm cov ntaub ntawv los ntawm tsib lub ntsiab lus. Nyob rau hauv ib lub thawv thiab whisker zajlus: qhov kawg ntawm lub thawv yog lub sab sauv thiab sab quartiles, yog li lub thawv spans lub interquartile ntau yam. qhov nruab nrab yog cim los ntawm ib txoj kab ntsug hauv lub thawv
Dab tsi yog qhov sib txawv ntawm cov txheej txheem programming thiab modular programming?
Structured programming yog qib qis ntawm coding hauv txoj kev ntse, thiab kev ua haujlwm modular yog qib siab dua. Modular programming yog hais txog kev sib cais qhov chaw ntawm cov kev pab cuam rau hauv kev ywj pheej thiab hloov pauv tau, los txhim kho kev sim, kev tswj xyuas, kev sib cais ntawm kev txhawj xeeb thiab rov siv dua
Dab tsi yog qhov zoo sib xws thiab qhov txawv ntawm relays thiab PLC yog dab tsi?
Relays yog electro-mechanical keyboards uas muaj coil thiab ob hom kev sib cuag uas tsis yog NO & NC. Tab sis Programmable Logic Controller, PLC yog lub khoos phis tawj me uas tuaj yeem txiav txim siab raws li qhov kev zov me nyuam thiab nws cov tswv yim & tso tawm
Dab tsi yog qhov sib txawv ntawm qhov ntsuas qhov ntsuas thiab qhov ntsuas thib ob?
Primary index: nyob rau hauv ib tug sequentially order file, qhov Performance index uas nws search key qhia cov sequential order ntawm cov ntaub ntawv. Kuj hu ua clustering index. Secondary index: ib qho Performance index uas nws qhov tseem ceeb tshawb nrhiav qhia qhov kev txiav txim sib txawv ntawm qhov kev txiav txim ntawm cov ntaub ntawv. Kuj hu ua non-clustering index
