Kuze kube yimanje, ama-flash drives yizindaba ezithandwa kakhulu zokugcina isitoreji. Ngokungafani nama-disks optical kanye magnetic (CD / DVD kanye nokushayela okunamandla, ngokulandelana), ama-flash drive ayanamathele futhi aphikisana nokulimala komshini. Futhi ngenxa yalokho okwenziwe ukuhlanganiswa nokuzinza? Ake sibone!
Kuyini ukushayela kwe-flash okuqukethe nokuthi kanjani
Into yokuqala okumele uyiqaphele ukuthi ayikho izingxenye ezihambayo ezihambayo ngaphakathi kwe-flash drive ezingabhekana nokuwa noma ama-jolts. Lokhu kufezwa ngumbono - ngaphandle kwecala elivikelayo, i-USB flash drive ibhodi lesifunda eliphrintiwe lapho ixhuma le-USB lidayiswa khona. Ake sibheke izingxenye zayo.
Izingxenye eziyinhloko
Izingxenye zezinkinobho eziningi ze-flash zingenziwa ngezigaba eziyisisekelo.
Okuyinhloko yilokhu:
- I-NAND memory chips;
- isilawuli;
- i-quartz resonator.
- Isixhumi se-USB
Inkumbulo ye-NAND
I-drive isebenza nge-NAND-inkumbulo: ama-chips semiconductor. I-chips yale nkumbulo yiyo, okokuqala, iyinkimbinkimbi kakhulu, futhi okwesibili - i-capacious kakhulu: uma okokuqala ama-flash drive ayelahlekelwa ngosayizi kuma-discs evamile, manje ngisho nama-Blu-ray ama-discs amancane ngamandla. Inkumbulo enjalo, phakathi kwezinye izinto, nayo ayiyona into engathandeki, okungukuthi, ayidingi umthombo wamandla wokugcina ulwazi, ngokungafani nezinombolo ze-RAM ezidalwe ngokusebenzisa ubuchwepheshe obufanayo.
Noma kunjalo, inkumbulo ye-NAND inesilinganiso esisodwa, uma siqhathaniswa nezinye izinhlobo zamadivayisi wokugcina. Iqiniso liwukuthi impilo yalezi chips inqunyelwe kwinani elithile lemijikelezo yokubhalwa kabusha (izinyathelo zokufunda ulwazi / izinyathelo zokubhala kumaseli). Ngokwesilinganiso, inani lemijikelezo yokufunda-ebhali liyi-30,000 (kuye ngokuthi uhlobo lwenkumbulo yolwazi). Kubonakala sengathi ikhulu kakhulu, kodwa empeleni kungu-5 iminyaka yokusetshenziswa okujulile. Kodwa-ke, noma ngabe umkhawulo ufinyelelwe, i-flash drive ingaqhubeka isetshenziselwa ukusetshenziswa, kodwa kuphela yokufunda idatha. Ngaphezu kwalokho, ngenxa yemvelo yayo, inkumbulo ye-NAND isengozini kakhulu ekukhuculweni kagesi nokugesi, ngakho-ke ungayishiyi emithonjeni yezingozi ezifanayo.
Umlawuli
Inomboro yesibili esithombeni ekuqaleni kwendima kukhona i-chip encane - isilawuli, ithuluzi lokuxhumana phakathi kwememori ye-flash kanye namadivayisi axhunyiwe (ama-PC, ama-TV, imisakazo yemoto, njll).
Isilawuli (okungenjalo esibizwa ngokuthi i-microcontroller) yikhompyutha encane encane eneprosesa yayo kanye nenani elithile le-RAM elisetshenziselwe i-caching data nezinhloso zesevisi. Ngaphansi kwenqubo yokuvuselela i-firmware noma i-BIOS isho nje ukubuyekezwa kwesofthiwe ye-microcontroller. Njengomkhuba wokubonisa, ukwehluleka okuvamile kwe-flash drives ukuhluleka kwesilawuli.
I-quartz resonator
Le ngxenye yinkimbinkimbi encane ye-quartz, okuyinto, njengokubuka kwe-elekthronikhi, ikhiqiza ukuchithwa kwe-harmonic yemvamisa ethile. Ezikhathini zokushayela, i-resonator isetshenziselwa ukuxhumana phakathi kwesilawuli, inkumbulo ye-NAND nezinye izingxenye ezengeziwe.
Le ngxenye ye-flash drive nayo isengozini yokulimala, futhi, ngokungafani nezinkinga ezine-microcontroller, akunakwenzeka ukuzixazulula wena. Ngenhlanhla, ama-resonators anamuhla awahluleki kakhulu.
Isixhumi se-USB
Esikhathini esiningi kakhulu samacala, i-USB yesimanje idrayivu ye-USB ifakwe ngoxhumano lwe-A 2.0 2.0, oluqondiswe ukuthola nokudlulisa. Amashayela amasha asebenzisa i-USB 3.0 Uhlobo A nohlobo C.
Izingxenye ezengeziwe
Ngaphandle kwezingxenye eziyinhloko ezikhonjiwe ngenhla yedivayisi yokugcina igesi, abakhiqizi bavame ukuzinika izinto ezikhethwa kukho, njengokuthi: isibonakaliso se-LED, inkinobho yokuvikelwa kokubhala, kanye nezinye izici ezithile eziqondene namamodeli athile.
Inkomba ye-LED
Amashayela amaningi e-flash ane-LED encane kodwa ekhanyayo. Yenzelwe ukubukeka ibonise umsebenzi we-flash drive (bhala noma ufunde ulwazi) noma umane nje uyingxenye yokuklama.
Le nkomba ngokuvamile ayithwali umthwalo osebenzayo we-flash drive ngokwayo, futhi kuyadingeka, eqinisweni, kuphela ukuze kube lula komsebenzisi noma ubuhle.
Bhala inkinobho yokuvikela
Lesi sici sivame kakhulu kumakhadi we-SD, nakuba ngezinye izikhathi itholakala kumadivayisi wesitoreji se-USB. Lezi zinsuku zivame ukusetshenziselwa imvelo njengabathwali bolwazi oluhlukahlukene, kubandakanya okubalulekile nokuyimfihlo. Ukuze ugweme izigameko ngokususwa ngengozi kwedatha enjalo, abakhiqizi be-flash drive kwezinye zezinhlobo zisebenzisa inkinobho yokuvikelwa: ukumelana ukuthi, uma uxhumeke ekunikezeni amandla kwemishini yememori, kuvimbela amandla kagesi ukuba angafinyeleli kumangqamuzana enkumbulo.
Uma uzama ukubhala noma ukususa ulwazi kusuka ku-drive lapho kuvulwa khona amandla, i-OS izobonisa lo mlayezo.
Ngokufanayo, ukuvikelwa kusetshenziselwa okuthiwa yizikhiye ze-USB: ukushayela okukhanyayo, okuqukethe izitifiketi zokuphepha ezidingekayo ukuze kusebenze kahle kwesofthiwe ethile.
Lesi sici singabuye siphume, okwenza kube nesimo esicasulayo - idivayisi ibonakala isebenza, kodwa akunakwenzeka ukuyisebenzisa. Sinezinto ezingosini zethu ezingasiza ekuxazululeni le nkinga.

Izingxenye eziyingqayizivele
Lokhu kufaka phakathi, isibonelo, ukuba khona kwezixhumanisi Ukukhanyisa, i-microUSB noma Uhlobo lwe-C: ukushayela okuhambayo ngokukhona kwalabo okuhloswe ukuthi kusetshenziswe, kufaka phakathi kuma-smartphone namaphilisi.
Bheka futhi: Ungaxhuma kanjani i-flash drive ku-smartphone ku-Android noma i-iOS
Kukhona ukushayela okunesiphephelo esiphezulu sedatha eqoshiwe - banekhibhodi eyakhelwe ngaphakathi ekungeneni iphasiwedi yezinombolo.
Eqinisweni, lena inguqulo ephakeme kakhulu ye-switch-overwrite yokuvikela ukukhishwa ngenhla.
Izinzuzo zama-flash drive:
- ukuthembeka;
- umthamo omkhulu;
- i-compactness;
- ukumelana nokucindezeleka komshini.
Izinkinga ze-flash drive:
- ukwehluleka kwezingxenye;
- ukuphila komsebenzi okulinganiselwe;
- ubungozi emanzini we-voltage kanye nokukhishwa kwe-static.
Ukufingqa - i-flash-drive, kusukela endaweni yokubukwa kwezobuchwepheshe, kunzima kakhulu. Kodwa-ke, ngenxa yesakhiwo esiqinile nesimo sezinto ezincane, ukumelana okukhulu nemithwalo yemishini kufezwa. Ngakolunye uhlangothi, i-flash drive, ikakhulukazi ngemininingwane ebalulekile, kufanele ivikelwe emiphumeleni yamaconsi amandla noma ugesi wesiteji.
