Rau hnub tim, flash drives yog cov feem ntau nrov lwm cov ntaub ntawv muaj. Nyob rau hauv sib piv rau kho qhov muag thiab sib nqus disks (CD / DVD thiab nyuaj drives, ntsig txog), flash drives ntau compact thiab resistant mus txhua yam kev puas tsuaj. Thiab nyob rau cov nuj nqis ntawm uas compactness thiab stability tau tiav? Cia peb paub nws!
Yuav ua li cas yuav ua rau lub flash drive thiab yuav ua li cas
Cov thawj zaug uas tau muab sau tseg - hauv lub eeb-tsav tsis muaj tsiv txhua yam qhov chaw uas tej zaum yuav raug kev txom nyem los ntawm tej tee los yog concussions. Qhov no yog tiav los ntawm tus tsim - tsis muaj ib tug tiv thaiv lub cev, lub flash drive yog ib tug luam Circuit Court board uas tus USB connector yog soldered. Wb saib nyob rau hauv nws lub Cheebtsam.Main Cheebtsam
Composite qhov chaw ntawm feem ntau flash drives yuav tau muab faib mus rau hauv yooj yim thiab yeem.
Lub ntsiab khoom muaj xws li:
- Nand nco chips;
- xws li;
- quartz resonator.
- USB connector
Nand nco
Tus tsav tej hauj lwm vim lub Nand nco: semiconductor chips. Lub chips ntawm xws li ib tug nco, firstly, yog heev compact, thiab tib ob - heev capacious: yog hais tias nyob rau thawj lub sij hawm flash drives tau lossed los ntawm cov ib txwm kho qhov muag disks nyob rau ntawm lub sij hawm, tam sim no Blu-duab tshav discs txawm tshaj los ntawm lub capacitance. Tej nco, txhua tsav txhua yam, kuj tsis yog-volatile, uas yog, nws tsis yuav tsum tau ib lub hwj chim qhov twg los mus khw ntaub ntawv, nyob rau hauv sib piv rau lub RAM ntawm RAM, tsim los ntawm zoo xws li cov technologies.
Txawm li cas los, Nand-nco muaj ib tug disadvantage, nyob rau hauv kev sib piv nrog rau lwm cov hom ntawm cia li. Qhov tseeb yog tias cov kev pab cuam lub neej ntawm cov chips yog txwv los ntawm ib tug tej yam muaj pes tsawg tus ntawm overwriting mus (nyeem / sau-sau cov kauj ruam nyob rau hauv lub hlwb). Nyob rau nruab nrab, cov nqi ntawm NYEEM-sau mus yog 30,000 (nyob ntawm seb yam ntawm lub cim xeeb nti). Nws nkawd hais tias nws yog incredibly ib tug ntau, tab sis nyob rau hauv qhov tseeb nws yog kwv yees li 5 xyoos intensive siv. Txawm li cas los, txawm yog hais tias tus txwv no mus txog, tus flash drive yuav txuas ntxiv mus siv, tab sis tsuas yog rau cov kev nyeem ntawv cov ntaub ntawv. Nyob rau hauv tas li ntawd, vim nws cov xwm, Nand-nco yog heev lam tau lam ua hluav taws xob dauv thiab electrostatic ntswg, ces cia tseg los ntawm qhov chaw ntawm xws piam sij.
xws
Thaum tooj 2 nyob rau hauv lub xam nyob rau hauv thaum pib ntawm lub tsab xov xwm muaj ib tug me me nti - xws li, ib qhov txuas cuab tam ntawm flash nco thiab kev cob cog rua pab kiag li lawm (PCs, TVs, tsheb hauv xov tooj cua, thiab lwm yam).
Tus maub los (txwv tsis pub yog hu ua microcontroller) yog cov me me txheej txheej txheem nrog nws tus kheej cov ntaub ntawv siv los caching cov ntaub ntawv thiab lub hom phiaj. Nyob rau hauv lub firmware hloov tshiab txoj kev los yog BIOS yog meant cia li hloov lub microcontroller. Raws li kev xyaum qhia, lub rooj sib cav tshaj plaws ntawm flash drives yog qhov tsis ua hauj lwm ntawm lub maub los.
Quartz Realonator
Qhov kev tivthaiv no yog ib qho me me quartzrystal, uas, raws li nyob rau hauv cov moos hauv nruab nrog, ua kev ua kom zoo nkauj hauv qee qhov zaus. Hauv flash drives, tus resonator siv los sib txuas lus ntawm tus maub los, nand nco thiab cov khoom sib txawv.
Qhov no ntawm lub Flash Drive tseem muaj kev pheej hmoo ntawm kev puas tsuaj, thiab, tsis zoo li cov teeb meem nrog microcontroller, nws yuav luag tsis yooj yim los daws lawv. Hmoov zoo, hauv cov tsav niaj hnub, cov resonators tsis tshua muaj.
USB Txuas
Nyob rau hauv cov neeg thoob plaws feem ntau ntawm cov rooj plaub hauv flash niaj hnub ua rau lub txuas ntawm USB 2.0 hom a, tau txais thiab xa mus. Cov tsav tshiab no siv USB 3.0 hom A thiab hom C.
Txheej txheem ntxiv
Ntxiv nrog rau cov khoom siv tau hais saum toj no saum toj no, cov tuam ntxhab feem ntau muab cov lus qhia, sau cov ntaub ntawv tiv thaiv mus thiab qee cov qauv tshwj xeeb rau qee cov qauv.
Tus taw qhia LED
Hauv ntau lub flash tsav muaj ib qho me me, tab sis yog qhov ci ntsa iab. Nws yog tsim los pom kev ua si ntawm kev ua si ntawm flash drive (sau tseg lossis nyeem cov ntaub ntawv) lossis tsuas yog tsim qauv.
Qhov ntsuas no feem ntau tsis nqa tsis muaj kev thauj khoom rau lub flash drive nws tus kheej, thiab xav tau, nyob rau qhov tseeb, tsuas yog rau kev yooj yim ntawm tus neeg siv lossis kev zoo nkauj.
Ntaub Ntawv Kev Tiv Thaiv Hloov
Lub caij no yog cov yam ntxwv ntawm SD cards dua, txawm hais tias qee zaum tshwm sim ntawm USB ntim khoom. Cov tom kawg feem ntau siv nyob rau hauv ib puag ncig cov lag luam raws li cov neeg nqa khoom ntawm ntau cov ntaub ntawv, suav nrog cov tseem ceeb thiab tsis pub lwm tus paub. Txhawm rau zam cov xwm txheej nrog cov ntaub ntawv zoo li no, nyem cov qauv, thaum muaj kev tiv thaiv mus rau lub zog hluav taws xob, tsis pub hluav taws xob kom tau mus rau lub cim xeeb hlwb.
Thaum koj sim sau lossis rho tawm cov ntaub ntawv los ntawm tsav, uas kev tiv thaiv tau qhib, OS yuav muab cov lus zoo li no.
Ib yam li ntawd, kev tiv thaiv nyob rau hauv thiaj li hu ua USB yuam sij yog siv: Flash drive uas muaj cov ntawv pov hwm kev nyab xeeb uas muaj cov kev ruaj ntseg ntawm qee cov software tshwj xeeb.
Lub caij no tseem tuaj yeem rhuav tshem, ua rau muaj kev ntxhov siab - cov cuab yeej zoo li ua haujlwm zoo li ua haujlwm, tab sis nws tsis tuaj yeem siv nws. Peb muaj nyob ntawm peb lub xaib muaj cov khoom siv uas tuaj yeem pab daws cov teeb meem no.
Nyeem ntxiv: Yuav ua li cas tshem tawm ntawm kev sau ntawv ntawm lub eeb
Cov Txheej Txheem Txawv
Xws li tuaj yeem ntaus nqi, piv txwv li, muaj cov xob laim, microusb lossis hom-c connectors: flash drives nrog rau siv nrog rau cov smartphones thiab ntsiav tshuaj.
Saib ntxiv: Yuav ua li cas txuas lub eeb rau lub smartphone ntawm Android lossis iOS
Tseem muaj cov tsav tsheb ntau tshaj plaws ntawm cov ntaub ntawv kaw cia - lawv muaj cov khoom siv built-in for supital password.
Qhov tseeb, qhov no yog kev nce qib ntxiv ntawm cov kev tiv thaiv dhau los hloov sab saud.
Ntxiv ntawm Flash Drives:
- kev ntseeg tau;
- Muaj peev xwm loj;
- Kev sib cav;
- Kev ruaj khov rau cov neeg kho tshuab thauj.
Qhov tsis zoo ntawm Flash Drives:
- Lub fragility ntawm cov khoom sib xyaw;
- txwv kev pab lub neej;
- Tsis ruaj khov rau voltage thiab zoo li qub tawm.
Cia peb sau lub ntsiab lus flash-tsav, los ntawm ib qho txuj ci ntawm kev pom, yog qhov nyuaj heev. Txawm li cas los xij, vim muaj kev tsim kho-lub xeev thiab tej yam me me ntawm cov Cheebtsam, muaj kev tiv thaiv ntau rau cov neeg kho tshuab thauj tau tiav. Ntawm qhov tod tes, nyem drives, tshwj xeeb nrog cov ntaub ntawv tseem ceeb, nws yog qhov tsim nyog yuav tsum muaj kev nyab xeeb los ntawm cov hluav taws xob lossis hluav taws xob tsis zoo li.
