Kubalulekile: Inxalenye yesistimu exhunyiwe ye-USB, kubandakanywa umphathi (njengekhomputha), ikhebula kunye nesixhobo, sonke sinokuxhasa imilinganiselo ye-USB eyahlukeneyo ngokude xa ihambelana nomzimba. Nangona kunjalo, zonke iindawo kufuneka zixhase umgangatho ofanayo ukuba ufuna ukuba zifikeleleke kwizinga eliphezulu leedata ezikhoyo.
USB Connectors
Kukho iinombolo ezahlukeneyo ze-USB, zonke ezichazwe ngezantsi. Jonga i- USB yethu Isatifiketi sokuBambisana ngokomzimba kwiphepha elilodwa lephepha-nento.
Iphulo: Umnxeba wesilisa kwi-cable okanye i-flash drive ngokuqhelekileyo kuthiwa iplagi . Umxhasi wesibini kwisixhobo, ikhomputha, okanye intambo yokwandisa ibizwa ngokuba yi- receptacle .
- Uhlobo lwe-C C : Ngokuqhelekileyo ekubhekiswe kuthiwa yi- USB-C , ezi zixube kunye nezikhuni ziyi-rectangular shape kunye neekota ezijikelezileyo. I-USB kuphela yohlobo lwe-C neepokethi (kwaye ke izixhobo) zikhona kodwa i-adapters ngokuhambelana ne-backwards ne-USB 3.0 ne-2.0 connectors zikhoyo.
- Uhlobo lwe-A lwe-USB : Ngokusemthethweni kuthiwa yi- USB Standard-A , ezi iplagi kunye neemfono zibuxhakaxhexhe kwaye zizona zixhamla zixhamla kwi-USB. I-USB 1.1 Uhlobo lwe-A, i-USB 2.0 Udidi lwe-A kunye ne-USB 3.0 Uhlobo lwe-plugs kunye ne-receptacles zihambisana ngokusemgangathweni.
- Uhlobo lwe-USB B : ngokusemthethweni kuthiwa yi- USB Standard-B , ezi zikhuni kunye nezikhuni zenziwe ngesikwere sineenotshi ezingaphezulu, ezibonakalayo kwii-connectors ze-USB 3.0 zeB. I-USB 1.1 Uhlobo lweB B kunye ne-USB 2.0 Uhlobo lwe-plugs B luhambelana nemeko ye-USB 3.0 yohlobo lwe-B kodwa ii-plug-in ze-USB 3.0 zohlobo lwe-B azihambelani ne-USB 2.0 Uhlobo B okanye i-USB 1.1 Uhlobo lwe-B.
- Isixhamli se-USB esixhaswe yi-USB sichazwe kwinqanaba le-USB 3.0. Esi samkeleko sihambelana kakuhle ne-USB 1.1 kunye ne-USB 2.0 Standard-B, kunye ne-USB 3.0 Standard-B kunye ne-Powered-B.

- I-USB Micro-B: Iiprogigi ze-Micro-B ze-USB 3.0 zibukeka zifana ne-USB 3.0 Micro-A plugs ezibonakala ngathi zimbini, kodwa zixhunyiwe, iiplagi. I-3.0 3.0 Iiprogiji ze-Micro-B ziyahambelana nezibilini ze-USB 3.0 ze-micro-B kunye ne-USB 3.0 Micro-AB.
- I-2.0 2.0 Iiprogigi ze-Micro-B zincinci kakhulu kwaye zixakile kodwa zineembombo zombini kwelinye lamacala amaninzi. Iiprogigi ze-Micro Micro B zixhamene ngokomzimba kunye ne-USB 2.0 Micro-B kunye ne-Micro-AB, kunye ne-USB 3.0 Micro-B kunye ne-Micro-AB.
- I-Mini Mini-A ye-USB: I-USB 2.0 ye-Mini-A iplagi isesigxina ngendlela kodwa elinye icala lijikeleze. I-USB Mini-A iiplagi zihambelana kuphela neenqwelo ze-USB Mini-AB. Akukho ikhonkco ye-Mini 3.0 ye-Mini.
- I-Mini Mini-B ye-USB: I-plug ye-USB 2.0 ye-Mini-B iyimimiselo yecala kunye nesincinci esincinane ngapha nangapha, ecaleni ngathi ibonakala njengesahluko sesonka xa sijonge. Iiprogigi ze-Mini Mini-B zihambelana ngokusemzimbeni kunye nezikhuni ze-USB 2.0 Mini-B kunye ne-Mini-AB. Akukho nxube ye-Mini 3.0 ye-Mini-B.
Qaphela: Kuze kube lula, akukho i-USB Micro-A okanye i-USB Mini-A izithuthi , kuphela iiprogi ze-USB Micro-A kunye ne-USB Mini-A plugs . Ezi "plug" zifakwe kwi-"AB".
