I-USB ithetha "Ibhasi yeSiriyeli yeHlabathi", igama lesiTshayina yibhasi yeUniversal Serial Bus.Le yitekhnoloji entsha yojongano esele isetyenziswa kakhulu kwintsimi yePC kwiminyaka yakutshanje.I-interface ye-USB ineempawu zesantya sothumelo olukhawulezayo, inkxaso yeplagi eshushu, kunye noqhagamshelo lwezixhobo ezininzi.Isetyenziswe ngokubanzi kwizixhobo ezahlukeneyo zangaphandle.Kukho iintlobo ezintathu zojongano lwe-USB: i-USB1.1 kunye ne-USB2.0, kunye ne-USB3.0 evele kwiminyaka yakutshanje.Kwithiyori, isantya sokuhanjiswa kwe-USB1.1 sinokufikelela kwi-12Mbps / s, ngelixa i-USB2.0 inokufikelela kwi-480Mbps / s, kwaye ukuhambelana ngasemva kunokuba yi-USB1.1.Ngophuhliso olukhawulezayo lwezixhobo zekhompyuter, ngakumbi nangakumbi iiperipherals, izitshixo, iimpuku, iimodem, abashicileli, iiskena kudala zaziwa, iikhamera zedijithali, abadlali beMP3 nabo balandela.Sifikelela njani kwiiPC ngezixhobo ezininzi kangaka?I-USB yazalelwa oku.Imarike inemfuno enkuluIzixhumi ze-USB, ingakumbi imveliso yokudibanisa i-USB engenamanzi.Oku kungenxa yokuba izisombululo ze-USB zemveli azikwazi ukuhlangabezana neemfuno zeemveliso zabathengi.Kule mihla, ingxinano yeemveliso zabathengi iya phezulu kwaye iphezulu, iimfuno zothumelo ziphezulu, kwaye imfuno yobonelelo lwamandla iyakhankanywa, kwaye kufuneka isetyenziswe kwiindawo ezininzi.Iimfuno zoyilo ze-USB izixhumi ezingangeni manzi zingashwankathelwa njenge: imfezeko yomqondiso, ukusetyenziswa kwamandla, ukukhuselwa kokusingqongileyo: 1. Iimfuno zembonakaliso yesignali Ukuphakama kwengqibelelo yesignali, ngokukhawuleza izinga ledatha.2. Iimfuno zokusetyenziswa kwamandla 3. Iimfuno zokhuseleko lokusingqongileyo Ukuze unikeze ukhuseleko lokusingqongileyo olufunwa ngabasebenzisi, iziqhagamshelo ze-USB ezingenamanzi kufuneka zibe netywina lerabha kunye neqokobhe elingenamthungo ukuze lingangeni manzi, ezi ziqhagamshelo kufuneka zibe yi-IPX8 yokungangeni manzi (ngokwe-IEC 60529), kwaye kufuneka yomelele ngokwaneleyo ukuba idityaniswe kwaye ikhutshwe amawakawaka amaxesha .
