Hom piv txwv ntawm cov khoom siv uas muaj firmware yog embedded systems, neeg siv khoom, computers, computer peripherals, thiab lwm yam. Yuav luag txhua yam khoom siv hluav taws xob tshaj qhov yooj yim tshaj plaws muaj qee qhov firmware . Firmware muaj nyob rau hauv cov khoom siv tsis muaj zog xws li ROM, EPROM, lossis flash nco.
Tsis tas li ntawd, leej twg ntawm cov hauv qab no yog cov ntsiab lus dav dav rau qhov kev zov me nyuam uas tuav cov ntaub ntawv kaw lus?
CMOS yog ib lub ntsiab lus dav dav rau qhov kev zov me nyuam uas khaws cov ntaub ntawv tseem ceeb ntsig txog qhov pib ntawm a lub computer . Cov ntaub ntawv tuav hauv CMOS suav nrog cov hard disk hom configuration, qhov kev txiav txim ntawm khau raj li sim, thiab lwm yam configurable chaw muaj feem xyuam rau lub system hardware.
Qhov thib ob, qhov xwm txheej ntawm kev sib koom ua ke NIC yog dab tsi? Ib Integrated NIC (Network Interface Card) yog Ethernet maub los suav nrog ua ib feem ntawm motherboard ntawm lub computer. Raws li Ethernet tau dhau los ua ntau yam hauv kev sib txuas cov khoos phis tawj mus rau txhua yam ntawm lub network hauv zos mus rau Is Taws Nem thiab cov tshuab luam ntawv, daim npav network tau ua ib txwm ua rau feem ntau cov khoos phis tawj ntawm lub hoobkas.
Ib yam li ib tug yuav nug, dab tsi yog lub luag haujlwm ntawm CMOS hauv lub computer niaj hnub?
Cov CMOS yog ib feem ntawm lub cev ntawm lub motherboard: nws yog lub cim xeeb nti uas lub tsev teeb tsa thiab yog siv los ntawm lub roj teeb onboard. Cov CMOS rov pib dua thiab poob tag nrho cov kev cai teeb tsa yog tias lub roj teeb tsis muaj zog, Tsis tas li ntawd, lub kaw lus moos rov pib dua thaum lub CMOS poob zog.
Koj yuav tsum ua dab tsi ua ntej flashing BIOS?
Kev ceev faj ua ntej hloov kho BIOS
- Ua ntej, thaub qab koj cov ntaub ntawv.
- Thaub qab koj li BIOS tam sim no, yog tias koj ua tau.
- Sau koj cov ntaub ntawv kev teeb tsa hard drive.
- Sau lwm qhov tsis zoo ntawm BIOS nqis, xws li hard disk hloov pauv tus nqi nqis, built-in serial thiab parallel chaw nres nkoj, thiab lwm yam.

Qhov twg hauv qab no yog ib qho piv txwv ntawm kev tswj hwm database?
DBMS. Qee qhov piv txwv DBMS suav nrog MySQL, PostgreSQL, Microsoft Access, SQL Server, FileMaker, Oracle, RDBMS, dBASE, Clipper, thiab FoxPro. Txij li thaum muaj ntau ntau cov kev tswj hwm database muaj, nws yog ib qho tseem ceeb kom muaj ib txoj hauv kev rau lawv sib txuas lus
Dab tsi yog qhov sib txawv tseem ceeb ntawm Amazon EBS thim rov qab thiab piv txwv khw Rov qab piv txwv?
Dab tsi yog qhov sib txawv tseem ceeb ntawm Amazon EBS-txhawb thiab qhov piv txwv-khoom txhawb nqa? Amazon EBS-rov qab piv txwv tuaj yeem nres thiab rov pib dua. Instance-store backed instances tuaj yeem nres thiab rov pib dua. Nws pib scaling yuav tsum siv Amazon EBS-rov qab piv txwv
Qhov twg hauv qab no yog ib qho piv txwv ntawm kev nco txog txheej txheem?
Cov txheej txheem nco yog ib hom kev nco mus sij hawm ntev uas cuam tshuam txog kev ua haujlwm sib txawv thiab kev txawj ntse. Caij tsheb kauj vab, khi koj nkawm khau, thiab ua noj omelet yog tag nrho cov piv txwv ntawm cov txheej txheem nco
Qhov twg hauv qab no yog ib qho piv txwv ntawm daim ntawv thov kos npe?
Piv txwv ntawm cov tshuab embedded muaj xws li tshuab ntxhua khaub ncaws, tshuab luam ntawv, tsheb, koob yees duab, tshuab ua haujlwm thiab lwm yam. Nyob rau hauv rooj plaub koj xav tsis thoob, yog, cov xov tooj ntawm tes thiab ntsiav tshuaj kuj suav hais tias yog cov khoom siv kos duab. Embedded systems muaj npe xws li vim tias lawv yog ib feem ntawm cov cuab yeej loj, muab cov haujlwm tshwj xeeb
Qhov twg hauv qab no yog ib qho piv txwv ntawm kev nco tsis muaj zog?
Piv txwv ntawm lub cim xeeb uas tsis yog-volatile muaj xws li flash nco, nyeem nkaus xwb (ROM), ferroelectric RAM, feem ntau hom sib nqus computer cia li (xws li hard disk drives, floppy disks, thiab magnetic daim kab xev), optical discs, thiab thaum ntxov lub computer cia txoj kev. xws li ntawv daim kab xev thiab punched cards
