USBstandsfor"UniversalSerialBus."Itwascreatedtomaketheconnectionsbetweencomputers

Now,thereareseveraltypesofUSBconnectors:
●USB-A
●USB-B
●USB-C
●USBMicro-A
●USBMicro-B
●USBMini-B(5-Pin)
●USBMini-B(4-Pin)
●USB3.0A
●USB3.0B
●USB3.0MicroB
●USB-AtoMicro-B
●USBMini-B(FujiⓇ)
Let’slearnmoreaboutUSB-A,USBMicro-A,USBMicro-B,andUSB-AtoMicro-B.
