tsis yog - volatile nco . Hom ntawm nco uas khaws lawv cov ntsiab lus thaum fais fab tuag. ROM yog nonvolatile , hos RAM yog tsis hloov pauv . Lo lus no feem ntau hais txog CMOS nco hauv PCs uas tuav lub BIOS.
Tom qab ntawd, ib tug kuj yuav nug, vim li cas ROM yog tsis hloov pauv nco?
ROM uas yog nyeem xwb nco yog nonvolatile vim tias tag nrho cov ntaub ntawv hauv nws tsis tau tshem tawm tom qab kaw lub computer thiab rov pib dua. Qhov twg RAM uas yog random access nco yog tsis hloov pauv vim hais tias tag nrho cov ntaub ntawv nyob rau hauv nws tau erased tom qab kaw lub computer thiab restarting nws.
Ib tug kuj nug, yog ROM volatile cia? A ROM chips yog tsis volatile cia nruab nrab, uas txhais tau hais tias nws tsis tas yuav muaj lub zog los khaws cov ntaub ntawv khaws cia ntawm nws. Ntawm qhov sib txawv, RAMchip yog tsis hloov pauv , uas txhais tau tias nws poob tej ntaub ntawv uas nws tuav thaum lub hwj chim raug muab tua.
Qhov sib thooj, puas yog DRAM tsis hloov pauv lub cim xeeb?
Cov khoom siv tsis raug tuaj yeem raug sib tw thiab tshem tawm. Tsis yog - tsis hloov pauv random-nkag mus nco (NVRAM) israndom-access nco uas yog tsis yog - tsis hloov pauv . Qhov no yog qhov sib piv rau dynamic random-access nco ( DRAM ) thiab static random-access nco (SRAM), uas ob leeg tswj cov ntaub ntawv tsuas yog ntev npaum li lub zog siv.
Puas yog RAM lossis ROM hloov pauv?
RAM yog hom tsis hloov pauv nco. Thaum koj kaw koj lub computer cov ntaub ntawv khaws cia hauv RAM yog deleted. ROM yog hom uas tsis yog- tsis hloov pauv nco. Cov ntaub ntawv hauv ROM yog sau tas mus li thiab tsis tau muab tshem tawm thaum koj poweroff koj lub computer.

Lub cim xeeb tseem ceeb thiab lub cim xeeb thib ob yog dab tsi muab piv txwv?
Lub cim xeeb thib ob muaj nyob rau hauv ntau thiab ib txwm loj dua lub cim xeeb thawj. Lub khoos phis tawj tuaj yeem ua haujlwm yam tsis muaj lub cim xeeb thib ob raws li nws lub cim xeeb sab nraud. Cov piv txwv ntawm lub cim xeeb thib ob yog lub hard disk, floppy disk, CD, DVD, thiab lwm yam
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
Puas yog CD ROM yog lub cim xeeb sib nqus?
CD-ROM yog lub cim xeeb semiconductor' yog FALSE nqe lus. Compact Disc-Read-Only Memory, ib hom optical disk muaj peev xwm khaws cov ntaub ntawv loj - txog li 1GB, txawm hais tias qhov loj tshaj plaws yog 650MB (megabytes). Muaj ob lub chaw khaws ntaub ntawv hluav taws xob uas peb tuaj yeem siv tau, sib nqus lossis kho qhov muag
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
