1 .Intshayelelo

　　USB interface connectors ziguquguquka kakhulu kubomi bale mihla kwaye ziye zaba sesona sixhobo siphambili sonxibelelwano lwedatha kunye nonxibelelwano phakathi kweePC kunye nezinye izixhobo zombane. Iindidi zahlulahlulwe zaziindidi ezintathu: USB Type-A interface isinxibelelanisi, USB Type-B interface connector kunye ne-USB Type-C isidibanisi interface. Phakathi kwazo, isidibanisi se-USB Type-B sisetyenziswa ikakhulu kwizixhobo zobukhulu obukhulu, kwaye eyona ixhaphakileyo sisixhobo somshicileli.

　　2. Kukho iinguqulelo ezimbini eziphambili ze-USB Type-B

　　1、Eyokuqala sisikwere USB Type-B isihlanganisi, edla ngokusetyenziselwa i-USB 2.0 okanye ngaphantsi.

　　2, Uhlobo lwesibini yi USB Type-B isiqhagamshelanisi, edla ngokusetyenziselwa i-USB 3.0 okanye ngaphezulu.

　　　Nangona i- USB2.0 Isidibanisi soHlobo lwe-B ibuyela ngasemva iyahambelana ne-USB 1.0, isenokungahambelani phambili nenye I-USB Type-B izibuko ze-USB 3.0 . I-USB Type-B port esetyenziselwa i-USB 3.0 yatshintshwa kamva ukuze ihambisane ne-USB 2.o kunye I-USB Type-B isinxibelelanisi esidibanisayo. Ukongeza kwimilinganiselo eyahlukeneyo, i-USB Type-B isidibanisi ye-USB 3.0 idla ngokuza neplagi eluhlaza okwesibhakabhaka.
