I-USB isho ukuthi “Universal Serial Bus”, igama lesiShayina i-Universal Serial Bus.Lona ubuchwepheshe obusha bokusebenzisana obusetshenziswe kabanzi emkhakheni we-PC eminyakeni yamuva.I-interface ye-USB inezici zesivinini sokudlulisa ngokushesha, ukusekelwa kokuxhuma okushisayo, nokuxhumeka kwamadivayisi amaningi.Isetshenziswe kabanzi kumadivayisi ahlukahlukene angaphandle.Kunezinhlobo ezintathu zokusebenzelana kwe-USB: i-USB1.1 ne-USB2.0, ne-USB3.0 evele eminyakeni yakamuva.Ngokombono, isivinini sokudlulisa se-USB1.1 singafinyelela ku-12Mbps/s, kuyilapho i-USB2.0 ingafinyelela ku-480Mbps/s, futhi ukuhambisana okusemuva kungaba yi-USB1.1.Ngokuthuthuka okusheshayo kwe-hardware yekhompiyutha, izinto ezizungezile, amakhibhodi, amagundane, amamodemu, amaphrinta, izikena sekuyisikhathi eside zaziwa, amakhamera edijithali, abadlali beMP3 nabo balandela.Siwafinyelela kanjani ama-PC ngamadivaysi amaningi kangaka?I-USB yazalelwa lokhu.Imakethe inesidingo esikhuluIzixhumi ze-USB, ikakhulukazi imikhiqizo yesixhumi se-USB esingangeni manzi.Lokhu kungenxa yokuthi izixazululo ze-USB zendabuko azisakwazi ukuhlangabezana nezidingo zemikhiqizo yabathengi.Kulezi zinsuku, ukuminyana kwemikhiqizo yabathengi kuya ngokuya kukhuphuka, izidingo zokudluliselwa ziphakeme, futhi nesidingo sokuhlinzekwa kwamandla kuyashiwo futhi, futhi kuyadingeka ukuthi sisetshenziswe ezindaweni eziningi.Izidingo zokuklama zezixhumi ezingangeni manzi ze-USB zingafingqwa njengokuthi: ubuqotho besignali, ukusetshenziswa kwamandla, ukuvikelwa kwemvelo: 1. Izidingo zobuqotho besignali Ukuphakama kobuqotho besignali, kuyashesha izinga ledatha.2. Izidingo zokusetshenziswa kwamandla 3. Izidingo zokuvikela imvelo Ukuze kuhlinzekwe ukuvikelwa kwemvelo okufunwa ngabasebenzisi, izixhumi ze-USB ezingangeni emanzini zidinga ukuba nezigxivizo zenjoloba kanye negobolondo elingenamthungo ukuze lingangeni manzi, lezi zixhumi kufanele zingangenwa amanzi nge-IPX8 (ngokwe-IEC 60529), futhi kufanele iqine ngokwanele ukuze ihlanganiswe futhi ikhishwe izikhathi eziyizinkulungwane.
