Lub xeev muaj zog ? Hard-drive feem ntau yog magnetic media , CDs yuav luag ib txwm kho qhov muag drives, flash drives yog lub ntsiab thiab feem ntau hom ntawm khov kho slate xov xwm.
Ntawm no, cov cuab yeej khaws cia hom twg yog cov xov xwm sib nqus?
Sib nqus cia siv ob hom sib nqus polarities los sawv cev rau cov ntaub ntawv binary suav nrog xoom thiab ib qho. Feem ntau siv cov khoom siv uas siv cov khoom sib nqus xws li cov ntaub nplaum sib nqus, floppy disks thiab hard-disk tsav.
Tsis tas li ntawd, puas yog lub hard disk magnetic optical lossis lub xeev ruaj khov? Lub platter nyob rau hauv hard disk tsav yog coated nrog a Sib nqus media uas sau cov ntaub ntawv hauv binary code (1's thiab 0's). A solid state tsav tsis muaj Sib nqus txheej txheej.
Nyob rau hauv txoj kev no, qhov sib txawv ntawm cov khoom sib nqus optical thiab cov khoom hauv lub xeev yog dab tsi?
Nyob rau hauv sib piv rau Sib nqus thiab kho qhov muag hom kev txhawb nqa khaws cia , cov cov khoom siv tsis muaj qhov txav txav thiab yog li hu ua ' solid state '. Hloov chaw, lawv siv hom tshwj xeeb ntawm programmable ROM nco nti ntawm cov ntaub ntawv twg khaws cia.
Ib qho piv txwv ntawm cov khoom hauv lub xeev cov xov xwm khaws cia yog dab tsi?
Ib qho yooj yim USB flash tsav (los yog tus ntiv tes xoo tsav ) yog ib piv txwv ntawm khov - xeev tsav tshuab. Ib SSD yog ib tug loj, ntau complex ntaus ntawv uas aggregates pas dej ntawm NAND flash khaws cia , hom ntawm khaws cia kuj pom nyob rau hauv MP3 players thiab cov koob yees duab digital.

Tus qauv twg yog siv los hloov cov ntaub ntawv kho mob thiab kev tswj hwm ntawm ntau lub tsev kho mob cov ntaub ntawv xov xwm HIS)?
Kev Noj Qab Haus Huv Qib Xya lossis HL7 yog hais txog cov txheej txheem thoob ntiaj teb rau kev hloov pauv cov ntaub ntawv kho mob thiab kev tswj hwm ntawm cov ntawv thov software siv los ntawm ntau tus kws kho mob. Cov qauv no tsom rau cov txheej txheem thov, uas yog 'txheej 7' hauv OSI qauv
Dab tsi yog qhov txawv ntawm cov ntaub ntawv davhlau ya nyob twg cov cuab yeej DTE thiab cov khoom siv sib txuas lus DCE)?
DTE (Data terminating equipment) thiab DCE (Data circuit terminating equipment) yog hom kev sib txuas lus serial. DTE yog ib qho khoom siv uas tuaj yeem ua tau raws li binary digital cov ntaub ntawv los yog qhov chaw. Thaum DCE suav nrog cov khoom siv uas xa lossis tau txais cov ntaub ntawv hauv daim ntawv digital lossis analog teeb liab hauv lub network
Cov cuab yeej twg xav tau rau koj lub PC sib txuas lus hauv xov tooj?
Luv luv rau modulator/demodulator, modem yog ib qho khoom siv kho vajtse uas tso cai rau lub computer xa thiab txais cov ntaub ntawv hauv xov tooj. Thaum xa cov teeb liab, lub cuab yeej hloov pauv ('modulates') cov ntaub ntawv digital mus rau lub teeb liab analog suab, thiab xa mus rau hauv xov tooj
Dab tsi ntawm cov hauv qab no yog qhov txiaj ntsig ntawm lub xeev cov khoom siv hluav taws xob sib nqus hard drive?
HDD tseem pheej yig dua SSD, tshwj xeeb tshaj yog rau cov tsav tshaj 1 TB. SSD tsis muaj qhov txav txav. Nws siv lub cim xeeb flash los khaws cov ntaub ntawv, uas muab kev ua tau zoo dua thiab kev ntseeg tau ntawm HDD. HDD muaj cov khoom txav thiab cov hlau nplaum sib nqus, txhais tau tias lawv siv ntau dua, lawv hnav sai dua thiab ua tsis tiav
Ob lub cuab yeej twg siv los txuas IoT cov cuab yeej rau hauv tsev network?
Muaj ntau yam khoom siv uas koj tuaj yeem siv los txuas rau Is Taws Nem ntawm Yam (IoT) cov khoom siv hauv tsev. Ob ntawm lawv suav nrog router thiab IoT rooj vag
