Zoyendetsa ma Flash ndi njira zodziwika kwambiri zosungira kunja. Mosiyana ndi ma disical ophatikizika ndi maginito (CD / DVD ndi ma drive ama hard, motero), ma drive ama flash amakhala ophatikizana kwambiri ndipo sagwirizana ndi kuwonongeka kwamakina. Ndipo chifukwa cha kuphatikiza ndi kukhazikika kwanji zomwe zidakwaniritsidwa? Tiyeni tiwone!
Kodi galimoto yamagalimoto imakhala ndi chiyani ndipo bwanji?
Choyambirira kudziwa ndichakuti palibe maginito oyenda mkati mwagalimoto yotchinga yomwe ingakhudzidwe ndi kugwa kapena kugwedezeka. Izi zimatheka chifukwa cha kapangidwe kake - popanda vuto loteteza, kungoyendetsa mawonekedwe ndi gawo loyendetsedwa lomwe USB cholumikizira chimagulitsidwa. Tiyeni tiwone mbali zake.
Zigawo zikuluzikulu
Zomwe zimayendetsa pamagalimoto ambiri zimatha kugawidwa ku pulayimale ndi sekondale.
Zomwe zikuluzikulu ndi izi:
- Chipangizo zokumbukira za NAND;
- wolamulira
- quartz resonator.
- Doko la USB
Chikumbutso cha NAND
Drayivala imagwira ntchito chifukwa cha NAND-memory: tchipisi cha semiconductor. Tinthu tomwe timakhala ndi chikumbutso chotere,, choyambirira, chophatikiza, ndipo chachiwiri, ndi champhamvu kwambiri: ngati poyambira kungoyendetsa ma voliyumu kutayika kwa ma disc omwe anali otchuka nthawi imeneyo, ma disc a Blu-Ray amapitilira mphamvu. Kukumbukira kotero, pakati pazinthu zina, kulinso kosasunthika, ndiye kuti, sikifunikira mphamvu yopangira chidziwitso, mosiyana ndi tchipisi vya RAM zopangidwa ndi ukadaulo wofananawo.
Komabe, kukumbukira kwa NAND kuli ndi drawback imodzi poyerekeza ndi mitundu ina ya zida zosungira. Chowonadi ndi chakuti moyo wautumiki wa tchipisi tomwe umakhala wocheperako ndi kuchuluka kwazomwe zimasintha (njira zowerengera / kulemba zambiri m'maselo). Pafupifupi, kuchuluka kwa mizere yolemba ndi 30,000 (kutengera mtundu wa chip memory). Izi zikuwoneka ngati ndalama zodabwitsa, koma kwenikweni ndi zaka 5 zogwiritsa ntchito kwambiri. Komabe, ngakhale malire atafikiridwa, kungoyendetsa pagalimoto kumatha kupitiliza kugwiritsidwa ntchito, koma kungowerenga deta. Kuphatikiza apo, chifukwa cha chilengedwe chake, kukumbukira kwa NAND kumakhala kosatetezeka kwambiri ndi magetsi amagetsi ndi zotulutsa zamagetsi, kotero siyani kutali ndi magwero a ngozi zotere.
Wolamulira
Nambala 2 pach chithunzi kumayambiriro kwa nkhaniyo ndi kakang'ono kakang'ono - wowongolera, chida cholumikizirana pakati pa kukumbukira kwa flash ndi zida zolumikizidwa (ma PC, ma TV, ma radio radio, ndi zina).
Wowongolera (mwanjira ina wotchedwa Microcontroller) ndi kompyuta yaying'ono yakale yokhala ndi purosesa yake komanso kuchuluka kwa RAM komwe kumagwiritsidwa ntchito posungira deta ndi ntchito zake. Njira yokwaniritsira firmware kapena BIOS imangotanthauza kungosintha pulogalamu ya microcontroller. Monga momwe masewera amasonyezera, zowononga zomwe zimachitika pakuwongolera pamagalasi ndi kulephera kwa wowongolera.
Quartz kristalo
Chipangizochi ndi kristalo kakang'ono kwambiri ka quartz, kamene kamaika pa wotchi yamagetsi, pamatha kupangika mosiyanasiyana mosiyanasiyana. Mukuwongolera pamagalasi, resonator imagwiritsidwa ntchito polumikizana pakati pa wowongolera, NAND-memory ndi zina zowonjezera.
Gawo ili la drive drive ilinso pachiwopsezo chowonongeka, ndipo, mosiyana ndi zovuta ndi ma microcontroller, ndizosatheka kuziwathetsa nokha. Mwamwayi, pamayendedwe amakono, ma resonators amalephera kawirikawiri.
Cholumikizira USB
Mwambiri pazochitika zambiri, pamagalimoto amakono amakono, cholumikizira USB cha mtundu wa USB chimayikidwa, chogwirizana ndi kulandira ndi kutumiza. Zoyendetsa zatsopano kwambiri zimagwiritsa ntchito USB 3.0 Type A ndi Type C.
Zowonjezera zina
Kuphatikiza pazinthu zazikulu za chipangizo cha memory memory chomwe chatchulidwa pamwambapa, opanga nthawi zambiri amawapatsa zinthu zomwe angazikonde, monga chizindikiro cha LED, cholembera chotchinga, ndi zina zomwe zimakhala ndi mitundu inayake.
Chizindikiro cha LED
Ma drive amaola ambiri amakhala ndi LED yaying'ono koma yowala bwino. Amapangidwira kuti azitha kuwonetsera zojambula zowoneka ngati kung'anima pagalimoto (kujambula kapena kuwerenga zambiri) kapena ndi chinthu chopanga.
Chizindikiro ichi nthawi zambiri sichikhala ndi katundu aliyense wogwira ntchito pagalimoto yoyendetsa yokha, ndipo chikufunika, makamaka, kungosavuta kwa wogwiritsa ntchito kapena kukongola.
Lembani switch
Izi zimakonda kwambiri makadi a SD, ngakhale nthawi zina amapezeka pazida zosungira USB. Zotsirizirazi nthawi zambiri zimagwiritsidwa ntchito m'makampani ngati onyamula zidziwitso zosiyanasiyana, kuphatikizapo zofunika komanso zachinsinsi. Pofuna kupewa zochitikachitika mwangozi mwanjira imeneyi, opanga ma drive mumayendedwe ena amagwiritsa ntchito switch yotchingira: choletsa, chomwe, chikalumikizidwa ndi gawo lamagetsi chamagetsi, chimalepheretsa magetsi kuti asafikire ma memory.
Mukayesa kulemba kapena kufufuta zambiri kuchokera pagalimoto pomwe chitetezo chimathandizidwa, OS imawonetsa uthenga.
Momwemonso, chitetezo chimakhazikitsidwa pazomwe zimatchedwa makiyi a USB: ma drive amoto omwe ali ndi ziphaso za chitetezo chofunikira pakugwiritsa ntchito pulogalamu inayake.
Izi zimathanso kuthyoka, zomwe zimapangitsa kuti pakhale nkhani yopsetsa mtima - chipangizocho chikuwoneka kuti chikugwira ntchito, koma ndizosatheka kuchigwiritsa ntchito. Tili ndi zinthu patsamba lathu zomwe zingathandize kuthana ndi vutoli.
Werengani zambiri: Momwe mungachotsere chitetezo pamakalata pa USB flash drive
Zapadera
Izi zimaphatikizapo, mwachitsanzo, kupezeka kwa ma Lightning, microUSB kapena Type-C cholumikizira: ma drive a ma flash ndi kukhalapo kwa omwe adapangidwira kuti azigwiritsa ntchito, kuphatikiza pa ma foni andule.
Onaninso: Momwe mungalumikizitsire USB flash drive kupita ku smartphone pa Android kapena iOS
Pali ma drive omwe ali ndi chitetezo chokwanira kwambiri cha mbiri yojambulidwa - ali ndi kiyibodi yomanga yolowera achinsinsi a digito.
M'malo mwake, iyi ndi mtundu wapamwamba kwambiri wa switch yotchinga yopitilira yomwe yatchulidwa pamwambapa.
Ubwino wamagalimoto akuwongolera:
- kudalirika;
- kuthekera kwakukulu;
- kuphatikiza;
- kukana kupsinjika kwamakina.
Zovuta zoyendetsa pamagalimoto:
- fragility ya zigawo zikuluzikulu;
- moyo wochepera;
- kusatetezeka kwamagetsi akutsikira ndikuzimitsa.
Kufupikitsa mwachidule - kuchokera pamawonekedwe aukadaulo, kuyendetsa kwa flash kumakhala kovuta. Komabe, chifukwa cha kapangidwe kokhazikika ka boma ndi kupangika kwa zinthuzo, kukana kwambiri kupsinjika kwamakina kumatheka. Kumbali inayi, kuyendetsa ma flash, makamaka ndi data yofunika, kuyenera kutetezedwa ku zovuta zamagetsi kapena magetsi amagetsi.
