Kusvika parizvino, flash matyairi ndiyo inonyanya kufarirwa kunze kwe data yekutakura. Mukupesana neye Optical uye magineti disks (CD / DVD uye DVD Drives, zvakatemerwa), Flash Drives iri kuomesa musoro uye kupokana nekukuvara kwemuchina. Uye pakubhadharwa kweiyo comakicy uye kugadzikana kwakawanikwa? Ngationgororei!
Chii chinoita kuti flash drive uye sei
Chinhu chekutanga chinofanira kucherechedzwa - mukati meiyo flash-drive hapana inofambisa mechaniki zvikamu izvo zvinogona kutambudzika nemadonhwe kana demo. Izvi zvinowanikwa kuburikidza neiyo dhizaini - pasina muviri unodzivirira, iyo flash drive ibwe rakadhindwa wedunhu iro iyo USB connector inotengeswa. Ngatitarisei pazvinhu zvacho.Zvikamu zvikuru
Zvikamu zvemanyorero emhando dzakawanda dzemvura dzinogona kukamurwa kuita basic uye sarudzo.
Zvinhu zvikuru zvinosanganisira:
- Nand Memory Chips;
- controller;
- Quartz Resonator.
- USB Connector
Nand Memory
Iyo drive inoshanda nekuda kweiyo Nand memory: semicononductor machipisi. Machiputi echirangaridzo chakadai, chekutanga, chakakomberedzwa, uye chechipiri - chakanyanya kunaka: Zvino kafura madhiri ekupedzisira panguva iyoyo, zvino Blu-ray discs zvinodarika nekugona. Ndangariro dzakadaro, nezvimwe zvese, zvakare zvisiri zvisina simba, kureva kuti, hazvitsvage simba rekuchengetedza ruzivo, zvakasiyana negondohwe regondohwe, rakagadzirwa neTemberi dzakafanana.
Nekudaro, nand-ndangariro ine imwe nzira yekukanganisa, mukuenzanisa nemamwe marudzi emidziyo yekuchengetedza. Icho chokwadi ndechekuti hupenyu hwebasa remachipisi aya hunogumira neyekuverengeka nhamba yekunyora (kuverenga / kunyora-kunyora matanho emasero). Paavhareji, huwandu hwehuwandu hwekuverenga-kunyora kuti zviuru makumi matatu (zvinoenderana nemhando yerangariro chip). Zvinoita sekunge zvakakura zvakanyanya, asi mune zvazviri zvinoda kusvika makore mashanu kushandiswa kwakanyanya. Nekudaro, kunyangwe kana chirevo chasvika, iyo flash drive inogona kuenderera mberi nekushandisa, asi chete yekuverenga data. Mukuwedzera, nekuda kwechimiro charo, nand-ndangariro hadzinganyevenesera kumadonhwe emagetsi uye magetsi anodzinga, saka zvichengete kubva kune zvinowanikwa nenjodzi dzakadai.
Controller
Pane nhamba 2 mune yekutanga kwechinyorwa kune chinyorwa chidiki chip - Controller, chinongedzo chechipfuva chekurangarira uye zvishandiso zvakabatana
Iye anotonga Pasi peiyo firmware yekuvandudza maitiro kana bios inoitirwa kungoisa iyo microcontroller. Sezvo tsika yekuratidzira, iyo inowanzo kupwanywa kweFlash Drives ndiko kutadza kweanodzora.
Quartz Resonator
Ichi chikamu chidiki chidiki quartz crystal, iyo, seyakawona yemagetsi, inoburitsa zvinokatyamadza zvakabatana mune imwe frequency. Mune flash madhiraivha, iyo resonator inoshandiswa kutaurirana pakati peanodzora, Nand memory uye zvimwe zvinhu.
Ichi chikamu cheiyo flash drive iri zvakare panjodzi yekukuvara, uye, zvisingaonekwi matambudziko ne microcoller, zvinenge zvisingaite kugadzirisa. Neraki, mumitambo yemazuva ano, vanodzikisira vanokundikana zvisingawanzo.
USB Connector
Muhuwandu hwekuwedzera kwezviitiko mumazuva ano flash anotyaira chinongedzo che USB 2.0 mhando a, kugamuchira uye kuendesa. Iyo New Trives Shandisa USB 3.0 Type A uye Type C.
Zvimwe zvikamu
Pamusoro pezvinhu zvataurwa pamusoro apa zvechidimbu chechidimbu, vagadziri vanowanzo kuvapa zvisarudzo zveshuwa, vakadai se: LED chiratidzo, kurekodha kuchinjika kuchinjika uye zvimwe zvinhu zvakati kune mamwe mhando.
LED inoratidza
Mune akawanda madhiraivha anotyaira pane vadiki, asi zviri nani kupenya. Iyo yakagadzirirwa kuratidza kuoneka chiitiko cheiyo flash drive (kurekodha kana kuverenga ruzivo) kana ingori chinhu chesarudzo.
Ichi chiratidzo chinowanzoita chisiri kutakura mutoro unoshanda kune flash drive pachayo, uye inodiwa, kutaura zvazviri, chete nekuda kwekurerutsa mushandisi kana kuti kune runako.
Rekodhi dziviriro switch
Chinhu ichi hunhu hwemakadhi eSD pane, kunyangwe dzimwe nguva zvichiitika pane USB yekuchengetedza michina. Iyo yekupedzisira inowanzoshandiswa munzvimbo yemusangano sevatakuri vemhando dzakasiyana siyana, kusanganisira dzakakosha uye dzakavanzika. Kuti udzivise zviitiko zvisina tsarukano
Paunoyedza kunyora kana kudzima ruzivo kubva ku drive, umo kuchengetedzwa kunogoneswa, iyo OS ichaburitsa meseji.
Saizvozvo, dziviriro mune inonzi USB Keys inoitwa: Flash madhiraivha ane zvitupa zvekuchengetedza anodikanwa kuti ishandiswe chaiyo yeimwe software.
Chinhu ichi chinogona kupwanyawo, zvichikonzera mamiriro anotsamwisa - chishandiso chinoita senge chiri kushanda, asi hazvigone kuchishandisa. Isu tine pane yedu saiti pane zvinhu zvinogona kubatsira kugadzirisa dambudziko iri.
Verenga Zvakawanda: Maitiro Ekubvisa Kudzivirirwa Kubva Pakunyora pane Flash Drive
Zvikamu zvakasarudzika
Izvi zvinogona kuverengerwa, semuenzaniso, kuvapo kwemheni, type-c vanobatanidza: Flash Drives neHupo hweavo vanoitirwa kushandiswa kusanganisira pamapiritsi uye mahwendefa.
Onawo: Unganidza sei Flash drive kune imwe smartphone paApple kana iOS
Kune zvakare madhiraivha ane kudzivirirwa kwakanyanya kwedata rekodhi - ivo vane yakavakirwa-mukhibhodi yekupinda password yedhijitari.
Muchokwadi, iyi idanho repamusoro yeiyo yakanyanya kudzivirirwa kuchinjika kuchinjika pamusoro.
Mapuranga eFlash anodhonzera:
- kuvimbika;
- Hukuru hukuru;
- compalness;
- Kugadzikana kune manhamba mitoro.
Zvinokuvadza zveFlash Drives:
- Kusimuka kwezvinhu zvikamu;
- hupenyu husina basa rebasa;
- Volenerability kune voltage uye static discharge.
Ngatiteke kupfupisa iyo flash-drive, kubva kune imwe nzira yekuona, yakaoma. Nekudaro, nekuda kwekuvakwa kwakasimba-kwehukama uye miniature yezvikamu, kupokana kukuru kune mitoro yemitambo inowanikwa. Kune rimwe divi, flash drives, kunyanya ne data rakakosha, zvinodikanwa kuchengetedza kubva pesvedzero yeVoltage kana magadzirirwo emagetsi anodonhedza.
