Flash drive yog los ntawm qhov nrov tshaj plaws sab nraud cia xov xwm. Tsis zoo li cov khoos phis tawm thiab sib nqus (CD / DVD thiab lub zog nyuaj, feem), flash drive yog ntau dua compact thiab tiv taus cov tshuab puas. Thiab vim yog dab tsi compactness thiab ruaj ntseg tiav? Cia peb xam nws tawm!
Lub flash drive muaj thiab seb yuav ua li cas
Thawj qhov uas yuav tsum nco ntsoov yog tias tsis muaj txhua yam khoom txav mus rau sab hauv lub flash drive uas tuaj yeem cuam tshuam los ntawm kev ntog lossis poob siab. Qhov no tau ua tiav vim yog tus qauv tsim - tsis muaj qhov teeb meem tiv thaiv, lub eeb tsav yog daim npav luam tawm Circuit Court uas tus USB txuas yog soldered. Peb saib nws cov khoom hauv feem.
Lub ntsiab tivthaiv
Lub Cheebtsam ntawm feem ntau ntawm cov flash drive tuaj yeem muab faib ua thawj thiab theem nrab.
Qhov tseem ceeb suav nrog:
- NAND nco chips;
- maub los
- quartz resonator.
- USB chaw nres nkoj
NAND txoj kev nco
Tus tsav ua haujlwm ua tsaug rau NAND-nco: semiconductor chips. Cov chips ntawm xws li lub cim xeeb yog, thawj zaug, compact heev, thiab thib ob, muaj peev xwm heev: yog tias thaum xub thawj flash drives hauv ntim poob rau optical discs uas ib txwm nyob rau lub sijhawm ntawd, tam sim no txawm tias Blu-Ray discs tshaj qhov muaj peev xwm. Xws li lub cim xeeb, ntawm lwm yam, kuj tseem tsis-hloov pauv, uas yog, nws tsis xav tau lub zog los khaws cov ntaub ntawv, tsis zoo li RAM chips tsim siv cov thev naus laus zis zoo sib xws.
Txawm li cas los xij, NAND nco muaj ib qho tsis zoo piv rau lwm hom kev khaws khoom cia. Qhov tseeb yog tias lub neej kev pabcuam ntawm cov chips tau txwv los ntawm qee tus lej ntawm kev rov ua dua tshiab (cov kauj ruam rau kev nyeem / sau cov ntaub ntawv hauv hlwb). Qhov nruab nrab, tus lej ntawm kev nyeem-sau lub voj voog yog 30,000 (nyob ntawm seb hom lub cim xeeb). Qhov no zoo li tus nqi tsis txaus ntseeg, tab sis qhov tseeb nws yog li 5 xyoo ntawm kev siv hnyav. Txawm li cas los xij, txawm tias txoj kev txwv tau mus txog, lub flash drive tseem tuaj yeem siv, tab sis tsuas yog rau kev nyeem cov ntaub ntawv. Tsis tas li ntawd xwb, vim nws qhov xwm txheej, NAND nco tau yooj yim heev rau lub zog hluav taws xob thiab cov hluav taws xob tso hluav taws xob, yog li khaws nws kom deb ntawm qhov chaw ntawm cov xwm txheej zoo li no.
Xws li
Naj npawb 2 hauv daim duab thaum pib ntawm tsab xov xwm yog me me microcircuit - tus maub los, cov cuab yeej sib txuas lus ntawm flash nco thiab cov khoom siv sib txuas (PCs, TV, xov tooj cua, thiab lwm yam).
Tus maub los (txwv tsis pub hu ua microcontroller) yog cov khoos phis tawm me me nrog nws cov processor thiab qee qhov RAM tau siv rau kev khaws ntaub ntawv thiab chaw ua haujlwm. Cov txheej txheem rau kev hloov kho cov firmware lossis BIOS txhais tau tias tsuas yog hloov kho software ntawm microcontroller. Raws li kev coj ua qhia pom, qhov teeb meem feem ntau ua rau flash drive yog qhov tsis ua hauj lwm ntawm tus maub los.
Quartz siv lead ua
Qhov kev tivthaiv no muaj lub sijhawm me me quartz siv lead ua, uas, zoo li hauv lub moos hluav taws xob, ua rau muaj kev tsis haum rau qee yam. Hauv cov ntawv flash, cov resonator yog siv rau kev sib txuas lus ntawm tus maub los, NAND-nco thiab ntxiv cov khoom sib xyaw.
Qhov no ntawm lub flash drive tseem muaj kev pheej hmoo ntawm kev puas tsuaj, thiab, tsis zoo li cov teeb meem nrog lub microcontroller, nws yuav luag tsis tuaj yeem daws lawv tus kheej. Hmoov zoo, hauv cov tsav tsheb niaj hnub, cov resonators swb tsis tshua muaj nqi.
USB txuas rau
Feem ntau ntawm qhov teeb meem no, hauv flash drives niaj hnub, USB 2.0 hom A txuas txuas nrog, tsom rau kev txais tos thiab kev sib kis. Lub zog tshiab siv USB 3.0 Hom A thiab Hom C.
Cov khoom siv ntxiv
Ntxiv rau qhov tseem ceeb ntawm cov khoom siv flash nco tau hais los saum toj no, cov tuam txhab tsim khoom siv feem ntau nrog rau cov khoom xaiv tau, xws li ntsuas qhov taw qhia LED, qhov hloov sau-tiv thaiv, thiab qee qhov tshwj xeeb tshwj xeeb rau qee yam qauv.
Qhov taw qhia LED
Ntau lub teeb nyem muaj qhov me me tab sis zoo sib xws LED. Nws yog tsim kom pom cov kev ua ntawm lub flash drive (cov ntaubntawv povthawj lossis nyeem cov ntaub ntawv) lossis tsuas yog cov khoom tsim.
Qhov ntsuas no feem ntau tsis nqa lub nra ua haujlwm rau lub flash drive nws tus kheej, thiab xav tau, qhov tseeb, tsuas yog rau kev yooj yim ntawm cov neeg siv lossis rau kev zoo nkauj.
Sau kev tiv thaiv hloov
Cov ntsiab lus no ntau dua rau SD card, txawm hais tias qee zaum pom nyob ntawm USB cia khoom. Cov tom kawg feem ntau siv hauv cov lag luam ib puag ncig ua cov nqa khoom ntawm ntau cov ntaub ntawv, suav nrog cov tseem ceeb thiab tsis pub lwm tus paub. Txhawm rau zam kom tsis txhob muaj xwm txheej nrog txiav tawm ntawm cov ntaub ntawv no, cov tsim cov flash drive hauv qee tus qauv siv lub pob hluav taws xob tiv thaiv: lub resistor, uas, thaum txuas nrog lub cim xeeb ntawm lub zog hluav taws xob, tiv thaiv hluav taws xob tam sim no mus txog ntawm cov hlwb nco.
Thaum koj sim sau lossis rho tawm cov ntaub ntawv los ntawm lub zog hauv kev tiv thaiv uas muaj kev tiv thaiv, OS yuav tso tawm cov lus zoo li ntawd.
Ib txoj hauv kev zoo sib xws, kev tiv thaiv raug coj los siv hauv kev sib txuas ntawm USB cov yuam sij: cov khoom siv flash uas muaj cov ntawv pov thawj kev nyab xeeb tsim nyog rau kev ua haujlwm kom raug ntawm qee cov software tshwj xeeb.
Lub caij no tseem tuaj yeem tsoo, uas ua rau muaj qhov teeb meem tsis sib xws - lub cuab yeej zoo li ua haujlwm, tab sis nws tsis tuaj yeem siv nws. Peb muaj cov ntaub ntawv ntawm peb lub xaib uas tuaj yeem pab daws cov teeb meem no.

Cov Cheebtsam tsis zoo
Cov no suav nrog, piv txwv li, nyob ntawm Xob Laim, microUSB lossis Hom-C txuas: flash drive nrog lub xub ntiag ntawm cov yog npaj rau kev siv, suav nrog hauv smartphones thiab ntsiav tshuaj.
Saib ntxiv: Yuav ua li cas txuas cov USB flash drive rau lub smartphone ntawm Android lossis iOS
Muaj cov tsav tsheb nrog kev tiv thaiv ntau tshaj plaws ntawm cov ntaub ntawv kaw tseg - lawv muaj keyboard tsim-hauv rau nkag mus rau lo lus zais digital.
Qhov tseeb, qhov no yog kev hloov kho tshiab tshaj ntawm cov kev tiv thaiv rho hluav taws xob tau hais los saum toj no.
Zoo ntawm flash drive:
- kev ntseeg tau;
- muaj peev xwm loj;
- compactness;
- tsis kam mus rau kev nyuaj siab txhua yam.
Qhov tsis zoo ntawm flash drive:
- taus ntawm cov Cheebtsam sib xyaw;
- tsuas siv lub neej;
- qhov tsis zoo rau cov hluav taws xob tso tawm thiab tshem tawm hluav taws xob zoo li qub.
Tx ລວມ lub ntsiab - los ntawm cov tswv yim kev pom, ib qho flash drive yog qhov nyuaj heev. Txawm li cas los xij, vim muaj cov qauv tsim-xeev tsim thiab miniaturization ntawm lub Cheebtsam, kev cuam tshuam ntau dua rau kev kho tshuab kev ntxhov siab tau tiav. Ntawm qhov tod tes, flash drive, tshwj xeeb tshaj yog nrog cov ntaub ntawv tseem ceeb, yuav tsum muaj kev tiv thaiv los ntawm kev cuam tshuam ntawm kev xaim hluav taws xob lossis hluav taws xob zoo li qub.
