2024 Tus sau: Lynn Donovan | [email protected]. Kawg hloov kho: 2023-12-15 23:47
Ntau Cov Ntaub Ntawv Interface ( MDI ): Ib MDI cia koj qhib ntau dua ib daim ntawv nyob rau tib lub sijhawm. Cov MDI muaj ib lub qhov rais niam txiv, thiab muaj pes tsawg tus me nyuam qhov rais. Single Document Interface ( SDI ): Ib SDI qhib txhua cov ntaub ntawv hauv nws lub qhov rais thawj. Txhua qhov rais muaj nws cov ntawv qhia zaub mov, toolbar, thiab nkag hauv ua haujlwm bar.
Kuj paub yog, SDI thiab MDI yog dab tsi?
MDI stands rau "Multiple DocumentInterface" thaum SDI stands rau "Single DocumentInterface". Tab sis SDI txhawb nqa ib qho interface txhais tau tias koj tuaj yeem ua haujlwm tsuas yog ib daim ntawv thov ntawm ib lub sijhawm. Rau kev hloov ntawm cov ntaub ntawv MDI siv tshwj xeeb interface hauv lub parentwindow thaum SDI siv Task Manager rau qhov ntawd.
Ib sab saum toj, koj txhais li cas los ntawm MDI? MDI (Multiple Document Interface) yog MicrosoftWindows programming interface los tsim ib daim ntawv thov uas ua rau cov neeg siv ua haujlwm nrog ntau cov ntaub ntawv tib lub sijhawm. Txhua daim ntawv nyob rau hauv ib qho chaw sib cais nrog nws tus kheej tswj forscrolling.
Ntawm no, daim ntawv thov SDI thiab MDI yog dab tsi nrog piv txwv?
SDI stands rau Single Document Interface thaum MDI stands rau Multiple Document Interface. Cov ntaub ntawv tuaj yeem hloov tau yooj yim hauv cov MDI thaum hais kom ua qhov rais yog siv toswitch ntawm lawv nyob rau hauv SDI . Qhov zoo tshaj plaws piv txwv ntawm SDI yog windows notepad thaum zoo tshaj plaws piv txwv ntawm MDI yog qhov tseeb web browsers.
Dab tsi yog cov yam ntxwv ntawm MDI daim ntawv?
Cov yam ntxwv ntawm MDI Cheebtsam Nta ntawm daim ntawv niam txiv
- Tso tawm sai li sai tau thaum daim ntawv thov MDI pib.
- Ua raws li lub thawv rau lwm qhov rais.
- Cov ntawv qhia zaub mov ntawm daim foos menyuam muaj nyob rau ntawm daim ntawv niam txiv.
- Tsuas yog ib daim ntawv niam txiv MDI xwb.
- Ntau daim ntawv menyuam tuaj yeem qhib rau ib lub sijhawm.

Dab tsi yog qhov txawv ntawm qhov sib txawv hauv zos thiab thoob ntiaj teb hauv SQL Server?
Qhov sib txawv hauv zos tau tshaj tawm hauv ib qho kev ua haujlwm whereas Ntiaj teb hloov pauv tau tshaj tawm sab nraum lub luag haujlwm. Cov kev hloov hauv zos tau tsim thaum lub luag haujlwm tau pib ua tiav thiab ploj thaum lub luag haujlwm xaus, ntawm qhov tod tes, Ntiaj teb hloov pauv yog tsim raws li kev tua pib thiab ploj thaum qhov kev pab cuam xaus
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 txawv ntawm cov ntaub ntawv hom thiab qhov sib txawv?
Ib qho kev sib txawv yuav tsum muaj cov ntaub ntawv sib txuas nrog nws, piv txwv li nws tuaj yeem muaj cov ntaub ntawv xws li cov lej, lej lej, cov cim thiab lwm yam. Qhov sib txawv ntawm hom Integer khaws cov lej suav thiab tus cim typevariable khaws cov cim tus nqi. Thawj qhov sib txawv ntawm ntau hom ntaub ntawv yog lawv qhov loj me me
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
