Tsis yog - volatile nco feem ntau hais txog khaws cia hauv semiconductor nco chips , khw cov ntaub ntawv hauv floating-gate nco cov hlwb uas muaj offloating-gate MOSFETs (hlau-oxide-semiconductor field-effecttransistors), suav nrog flash nco cia xws li NANDflash thiab solid-state drives (SSD), thiab ROM chips xws li
Tom qab ntawd, dab tsi yog qhov khoom siv tsis hloov pauv hloov pauv?
Tsis yog - volatile cia (NVS) yog ib qho kev nthuav dav ntawm cov thev naus laus zis thiab khoom siv uas tsis tas yuav siv hluav taws xob txuas ntxiv mus khaws cov ntaub ntawv lossis cov program code txuas ntxiv mus rau lub sijhawm luv luv lossis ntev. NOR flash nco chipscommonly khw maub los code hauv khaws cia tsav tsheb thiab tus kheej hluav taws xob khoom siv.
Ib sab saum toj no, qhov chaw khaws cia yog volatile? Volatile nco yog computer khaws cia uas tsuas yog tswj nws cov ntaub ntawv thaum lub cuab yeej siv hluav taws xob. Feem ntau RAM (random access memory) siv rau thawj khaws cia nyob rau hauv tus kheej lub computer yog tsis hloov pauv nco.
Tsuas yog li ntawd, puas yog Hard drive tsis hloov pauv chaw cia?
Nyuaj drives, SSDs (khoom lub xeev drives), flashdrives, NVRAM, ROM, floppy disks , magnetic daim kab xev, opticaldiscs, punched daim kab xev, thiab punched phaib yog cov piv txwv ntawm hom no khaws cia . Lawv yog tsis yog - tsis hloov pauv vim cov ntaub ntawv khaws cia raug kaw nyob rau hauv ib txoj kev uas ua tsis yog xav tau ib lub zog los tuav cov ntaub ntawv.
Puas yog flash drive volatile lossis nonvolatile?
Nws tuaj yeem xa mus rau cov chips uas tsis hloov pauv, xws li ROMs thiab PROMs, lossis rau cov chips uas tuaj yeem rov sau ntau zaus xws li flash nco . Txawm li cas los xij, USB flash drives , nrog nyuaj tsav thiab solid state tsav (SSDs), yog tsis-volatile cov khoom siv khaws cia, tsis yog tsis-volatilememory.

Puas yog ROM yog lub cim xeeb tsis hloov pauv?
Non-volatile nco. Hom kev nco uas khaws lawv cov ntsiab lus thaum lub hwj chim raug kaw.ROM tsis hloov pauv, qhov RAM tsis hloov pauv. Lo lus no feem ntau hais txog CMOS nco hauv PCs uas tuav lub BIOS
Dab tsi yog qhov hloov pauv tsis siv neeg hloov pauv rau lub tshuab hluav taws xob?
Ib qho kev hloov pauv hloov yog ib qho hluav taws xob hloov hluav taws xob uas hloov lub nra ntawm ob qhov chaw. Ib qho Kev Hloov Hloov Tsis Siv Neeg (ATS) feem ntau tau teeb tsa qhov twg lub tshuab hluav taws xob thaub qab nyob, yog li lub tshuab hluav taws xob tuaj yeem muab hluav taws xob ib ntus yog tias qhov chaw siv hluav taws xob tsis ua haujlwm
Dab tsi yog qhov hloov pauv hloov pauv hloov pauv hauv Java?
Default access modifier txhais tau hais tias peb tsis qhia meej txog kev hloov pauv nkag rau hauv chav kawm, teb, txoj kev, thiab lwm yam. Ib qho kev hloov pauv lossis txoj kev tshaj tawm yam tsis muaj kev tswj xyuas kev hloov pauv yog muaj rau lwm chav kawm hauv tib lub pob
Vim li cas cov kev hloov pauv hloov pauv tsis yog serialized?
Transient yog Java lo lus tseem ceeb uas cim cov tswv cuab sib txawv tsis txhob raug serialized thaum nws pheej mus rau kwj ntawm bytes. Thaum cov khoom raug xa mus los ntawm lub network, cov khoom yuav tsum tau 'serialized'. Serialization hloov cov khoom lub xeev mus rau serial bytes
Puas yog ib qho kev hloov pauv hloov tshiab ua rau muaj kev ua haujlwm tau hais tseg ntawm kev hloov tshiab?
Cov qauv tsis ua rau 'cov ntaub ntawv hloov tshiab,' thiab yog li feem ntau tsis tuaj yeem tua tsis tau dab tsi (ua rau, cov cai ua haujlwm, ntws, cov lus tawm, thiab lwm yam). Koj tuaj yeem xaiv kom rov ua haujlwm rov ua haujlwm cov cai thaum qhov hloov tshiab ua rau cov ntaub ntawv hloov pauv, tab sis kuv tsis paub meej tias yuav pab tau koj li cas
