Java tau pib tsim nrog kev ruaj ntseg hauv siab, yog li theoretically nws yog heev ruaj ntseg . Java cov kev pab cuam downloaded los ntawm lub vev xaib tsis tuaj yeem nkag mus rau cov ntaub ntawv - nkaus xwb applets uas nyob hauv lub tshuab ua haujlwm tuaj yeem ua tau li ntawd, thiab lawv raug txwv rau cov neeg siv tau teev tseg ntawm cov npe thiab cov ntaub ntawv, nrog rau qib sib txawv ntawm kev nkag tau yooj yim.
Kuj tseem paub yog, puas yog Java applets ruaj ntseg?
Applet Security . Ib qho ntawm cov yam ntxwv tseem ceeb tshaj plaws ntawm Java yog nws kev ruaj ntseg qauv. Nws tso cai rau tsis ntseeg code, xws li applets rub tawm los ntawm cov vev xaib tsis ncaj ncees, kom khiav hauv qhov chaw txwv uas tiv thaiv cov cai ntawd los ntawm kev ua tsis zoo, xws li rho tawm cov ntaub ntawv lossis xa email cuav.
Qhov thib ob, kev siv applet yog dab tsi? Txheej txheem cej luam. Cov Applets yog siv los muab cov yam ntxwv sib tham sib rau web applications uas tsis tuaj yeem muab los ntawm HTML ib leeg. Lawv tuaj yeem ntes nas cov tswv yim thiab tseem muaj kev tswj hwm zoo li cov nyees khawm lossis kos lub thawv. Hauv kev teb rau cov neeg siv kev ua, ib applet tuaj yeem hloov cov ntsiab lus nraaj.
Yog li ntawd, applet programming yog dab tsi?
Ib applet yog Java qhov kev pab cuam uas khiav hauv Web browser. Applets yog tsim los embedded nyob rau hauv ib nplooj ntawv HTML. Thaum tus neeg siv saib nplooj ntawv HTML uas muaj ib qho applet , cov code rau cov applet yog downloaded rau tus neeg siv lub tshuab. JVM yuav tsum tau saib ib qho applet.
Vim li cas thiaj muaj ntau yam kev txwv hauv applet programming?
Feem ntau yog vim muaj kev ruaj ntseg, cov hauv qab no txwv raug yuam rau Java applets : Ib applet tsis tuaj yeem thauj cov tsev qiv ntawv lossis txhais cov txheej txheem ib txwm muaj. Ib applet tsis tuaj yeem nyeem lossis sau cov ntaub ntawv ntawm tus tswv tsev ua haujlwm. Ib applet tsis tuaj yeem ua kev sib txuas hauv network tshwj tsis yog rau tus tswv tsev tias nws tuaj ntawm.

Yuav ua li cas kuv thiaj li tau txais ib qho kev pab cuam los khiav ntawm kev pib ntawm Mac?
Ntxiv cov khoom pib rau koj Mac hauv SystemPreferences Nkag mus rau hauv koj lub Mac nrog tus lej koj siv nrog cov khoom pib. Xaiv qhov System nyiam los ntawm Apple cov ntawv qhia lossis nyem qhov System nyiam icon hauv Dock kom qhib qhov SystemPreferences. Nyem rau tus neeg siv & pab pawg icon (lossis Accounts hauv cov laus versions ntawm OS X)
Vim li cas kuv lub Apple ID raug kaw vim muaj kev ruaj ntseg?
Cov laj thawj feem ntau uas Apple IDgets xiam lossis raug kaw yog: Qee tus neeg sim nkag rau koj Apple ID tsis raug ntau zaus. Ib tug neeg nkag rau koj cov lus nug kev ruaj ntseg tsis raug ntau zaus. Lwm cov ntaub ntawv ntawm Apple ID nkag mus tsis raug ntau zaus
Qhov twg hauv qab no yog suav tias yog kev tswj hwm kev ua haujlwm ntawm kev tswj hwm database DBMS)?
Databases uas nqa lawv cov ntaub ntawv nyob rau hauv daim ntawv ntawm cov ntxhuav thiab uas sawv cev rau kev sib raug zoo siv txawv teb chaws yuam sij yog hu ua discrete databases. Kev tswj hwm kev ua haujlwm ntawm kev tswj hwm qhov system (DBMS) suav nrog thaub qab cov ntaub ntawv database
Dab tsi yog kev ruaj ntseg ruaj ntseg thiab muaj nyob rau hauv kev ruaj ntseg?
Kev ceev ntiag tug txhais tau hais tias cov ntaub ntawv, cov khoom thiab cov peev txheej raug tiv thaiv los ntawm kev tsis pom zoo thiab lwm yam kev nkag. Kev ncaj ncees txhais tau tias cov ntaub ntawv raug tiv thaiv los ntawm kev hloov pauv tsis tau tso cai los xyuas kom meej tias nws ntseeg tau thiab raug. Muaj txhais tau hais tias cov neeg siv tau tso cai nkag tau rau hauv cov tshuab thiab cov peev txheej uas lawv xav tau
Kuv yuav ua li cas thiaj ua tau ib qho kev pab cuam tsis ua haujlwm thaum pib Windows 10?
Hloov cov apps Yog tias koj tsis pom qhov kev xaiv Startup nyob rau hauv Chaw, txoj cai-nias lub Start khawm, xaiv Task Manager, ces xaiv lub Startup tab. (Yog tias koj tsis pom lub Startup tab, xaiv cov ntsiab lus ntxiv.) Xaiv lub app koj xav hloov, ces xaiv Enable los khiav nws thaum pib lossis Disable kom nws tsis khiav
