Yuav ua li cas yuav tsum ua li cas yog kuv lub computer tsis pom lub xov tooj ntawm USB

Txawm tias cov xov tooj txawb twb ua heev commonplace kev sib txuas lus kiag li lawm, muaj coob tus neeg tau tseg kev nyuaj siab ntau yam teeb meem nyob rau hauv lub lag luam los ntawm cov xov tooj txawb. Ib tug ntawm lawv yog hais tias lub computer system tsis pom lub xov tooj ntawm USB. Hais tias yog, thaum twg txuas mobile xov tooj rau ib tug muaj USB chaw nres nkoj siv tshwj xeeb cable nyob rau hauv lub operating system tsis tshwm ib tug tsav tsab ntawv - yog tsis muaj mount flash nco card (ua-nyob rau hauv los yog tus neeg siv-ntsia). Thiab yog hais tias koj ua hauj lwm nrog ib tug ntxiv flash card yog tseem tau nrog kev pab los ntawm ib tug sab nraud card nyeem ntawv, nkag tau mus rau seem ntawm lub built-in yog tsis yooj yim sua. Raws li ib tug tshwm sim, usability ntawm tus xov tooj yog significantly txo. Yog li ntawd yog vim li cas yog nws hais tias cov computer tsis pom lub USB-chaw nres nkoj ntawm mobile xov tooj?

Standards thiab nta

Muaj coob tus neeg yuav siv los hais tias tag nrho cov tseem ceeb functions ntawm tej ntaus ntawv yuav tsum ua hauj lwm "rau ntawm lub box", piv txwv li tsis yuav tsum tau muaj kev tshwj xeeb chaw. Nyob rau hauv lwm yam lus, tus xov tooj yog yuav tsum hais tias thaum koj txuas mus rau koj lub computer yuav tsum muab ib tug kev sib tham uas muaj qhov kov screen yuav ua rau ib tug xaiv ntawm cov kev khiav hauj lwm hom (them, modem, cia, thiab lwm yam). Txawm li cas los, nyob rau hauv ib co qauv, nws tsis tshwm sim, thiab lub tswv yog xaus lus tias cov computer tsis pom lub xov tooj ntawm USB. Nyob rau hauv kev, peb ntsib nrog no cov neeg siv Ib txhia smartphone "Samsung". Yog li ntawd ua ntej koj ntshai vim lub fact tias cov computer tsis pom lub xov tooj ntawm USB, koj yuav tsum ua tib zoo saib xyuas tag nrho cov khoom smartphone chaw. Yog li, nyob rau hauv lub saum toj no-hais "Samsung" qauv ua ntej txuas lawv mus rau "tej chaw", xaiv "Network" thiab qhib qhov khoom, xws li ib tug USB-tsav hom.

Suav hlau

Cov tom ntej no qhov teeb meem, vim hais tias cov neeg uas lub computer tsis pom lub xov tooj ntawm USB, yog kev siv ntawm tsawg-zoo tswv qaum mus cuag kiag li lawm. Suspiciously pheej yig cables tau ntev tau paub hais tias tus neeg xyuas pib nyob ntawm tej hauv tsis raws li cov cai rau kuj (tus ntoo khaub lig seem, cov ntaub ntawv uas), li ntawd, tej zaum thaum koj txuas lub computer tsis pom lub xov tooj ntawm USB. Tsis tas li ntawd, nyob rau hauv soldering connectors thiab tsawg zoo cov ntaub ntawv uas tsiv hu yog ntxiv txo kev ntseeg. Yog li ntawd nws yog pom zoo kom siv ib tug cable uas los bundled nrog lub ntaus ntawv, los yog mus yuav ib tug siab zoo. Nyob rau hauv cov ntaub ntawv no, ib qho los mus txuag on "khoom" yuav ua rau tom ntej teeb meem thaum siv koj lub xov tooj.

hloov qhov chaw nres nkoj

Dua li ntawm qhov nplua mais ntawm cov USB connectors rau motherboards thiab laptops, lawv muaj kev cob cog tsuas mus rau ntau yam controllers. Cov chips (los yog blocks), nyob rau hauv particular, cov mov ntawm cov tswj ports. Yog li, rau cov txheej txheem 2.0 chaw nres nkoj lub siab tshaj plaws tam sim no yog 500 ma. Txawm li cas los, vim rau qhov tseeb hais tias maj qhov tsis muaj hluav taws xob Cheebtsam pib "float" (capacitors poob capacitance nyob rau hauv lub coils muaj coiled-Circuit Court thiab thiaj li nyob.) Yuav tshwm sim teeb meem uas txuas rau lub hwj chim xav tau kiag li lawm. Uas yog, yog tias ib tug USB chaw nres nkoj lub modem yog kev cob cog rua (500 MA), thiab yog nyob rau tom ntej mus rau lub xov tooj puv, xws li yuav tsis tau leg lub load. Lub daws yog yooj yim: nyob rau hauv cov ntaub ntawv ntawm cov teeb meem nrog rau cov kev nrhiav kom tau ntawm lub kev cob cog rua mobile xov tooj yuav tsum tau switched nws mus rau lwm lub free chaw nres nkoj.

software failures

Tej zaum cov kev twb kev txuas blocks antivirus software ntsia koj lub computer. Nws yuav tsum tau mus ib ntus tsis taus. Thaum kawg, ntau cov neeg siv claim hais tias lawv tau pab los ntawm ib tug yooj yim reboot koj lub xov tooj thiab koj lub computer - mam li tsav txhais nyob rau hauv lub system.
