i-USByi "Universal Serial Bus", Igama lesiTshayina libizwa ngokuba yi-Universal Serial Bus.Le yitekhnoloji entsha yojongano olusetyenziswa ngokubanzi kwintsimi yePC kwiminyaka yakutshanje.Izibuko le-USB lineempawu zesantya sothumelo olukhawulezayo, inkxaso yokutshintsha okushushu kwaye uqhagamshele izixhobo ezininzi.Isetyenziswe ngokubanzi kuzo zonke iintlobo zezixhobo zangaphandle.Kukho iintlobo ezintathu zamazibuko e-USB: i-USB1.1, i-USB2.0, kunye ne-USB 3.0 yakutshanje.Ngokwethiyori, i-USB1.1 inokuhambisa isantya ukuya kuthi ga kwi-12Mbps/SEC, ngelixa i-USB2.0 inokuhambisa isantya ukuya kuthi ga kwi-480Mbps/SEC, kwaye ngasemva iyahambelana ne-USB1.1.
Njengoko hardware computer iphuhlisa ngesantya esipheleleyo, izixhobo peripheral ukwandisa imihla ngemihla, keyboard, mouse, modem, umshicileli, iskena sele yaziwa kubo bonke, ikhamera yedijithali, MP3 walkman iza enye emva kwenye, izixhobo ezininzi kangaka, njani ukufikelela kwikhompyutha yobuqu?I-USB yenzelwe le njongo.
Uphuhliso lwesinxibelelanisi se-USB kunye nendaleko kule minyaka ingama-20 idlulileyo
Nasiphi na isixhobo sekhompyutha sinokuthotywa kanobom kukungakwazi kwaso ukufumana nokusasaza idatha kumazwe angaphandle.Ukuthintelwa kwedatha kwi-input/output (I/O) iiphaneli zinciphisa ugqithiso lolwazi kwaye zenza izixhobo zingasebenzi kakuhle.Ukutyhubela iminyaka, i-15 - kunye ne-25-pin D-Sub connectors ziye zatshintsha kwikhono labo lokubonelela ngeeperipherals ngemilinganiselo eyaneleyo yokuhanjiswa kwedatha ye-I / O.Isuka kwizicelo zasemkhosini, ezi ziqhagamshelo ze-Mil-Spec zibonakalisa ipini ethembekileyo kunye noqhagamshelo lwesokethi, kunye nezindlu ezinqabileyo.Ukuguqula ezi ziqhagamshelo ze-Mil-Spec kwiinguqulelo zorhwebo kunye nokubeka amaxabiso kumgangatho wabathengi kubenza babe ngumgangatho wemveliso yabathengi, ngoku esetyenziswa ngokubanzi kwividiyo, izixhobo zekhompyutheni kunye nokunye.Njengoko imfuno yamazinga edatha inyuka ukusuka kwi-kilobytes ukuya kwi-megabytes, isithuba esincinci sifumaneka kwi-interconnections yangaphandle, efuna i-interfaces entsha yokudibanisa.Ngo-1996, i-usB-IF, i-consortium yeenkokheli ze-electronics industry, yazalwa kwaye yakhulula isizukulwana sokuqala samazibuko e-USB.Ukukhutshwa kokuqala yayiyinkcazo ephuculweyo ye-USB1.1 ejolise ekubuyiseleni ujongano loluhlu, oluchaphazele kakubi ukuhambelana phakathi kweeperipherals ezongeziweyo, kubandakanywa i-flash kunye ne-hard drives yangaphandle, iiskena kunye nabashicileli.Uqhagamshelo lwenziwa ngekhonkco elincinci loxande kunye nesantya sokuqala sokudluliselwa kwe-1.5Mb / s, kusetyenziswa uxhulumaniso lwamandla aphantsi kunye nobomi obumalunga namawaka amaxesha, kodwa kuphela kwicala elinye.
Inzuzo enkulu yomgangatho we-USB kukukwazi ukuhambisa amandla kunye nemiqondiso ngaxeshanye, okwenza izixhobo ezikude zisebenze ngaphandle kwamandla angaphandle.Ikhono "leplagi eshushu" yenye into ebalulekileyo kwiizibuko ze-USB.
Akho umxholo ngemigangatho ekhoyo, i-USB-IF ikhuphe i-USB 4 inkcazo ngoSeptemba 2019. Umdibaniso uya kugcina i-interface ye-Type-C, kodwa iya kudibanisa i-Intel Thunder 3 kunye ne-40GB / s izinga lokudlulisa iteknoloji.I-USB 4 ibuyela ngasemva iyahambelana ne-USB Type-C protocol, kuquka i-USB 3.2, i-DisplayPort, kunye ne-Thunder 3, yenza lula uqhagamshelwano kwisizukulwana esitsha sezixhobo.Izixhobo ezinolu jongano olutsha zilindeleke ngo-2021.
Usb-ukuba ubonisa ukuzibophelela kwayo ekuphuculweni okuqhubekayo, okwenza i-USB iqhubeke idlala indima ephambili ekuyilweni kwesizukulwana esilandelayo sezixhobo.
Leyo yimbali yeminyaka engama-20 yezixhumi ze-USB.Ngophuhliso oluqhubekayo lweteknoloji yehlabathi, ukutshintshwa kweemveliso ze-elektroniki.Izixhumi ze-USB zexesha elizayo nazo ziya kuhlaziywa ukuhlangabezana neemfuno eziphezulu.
