The history of the USB began way back in 1996, as a joint project between Intel, Microsoft, IBM, Compaq, DEC, NEC and Nortel to standardise hardware connections to computers. The following is a list of the main differences between the latest USB-C and previous USB models.
USB-C has a smaller input, just 8.2 millimetres wide by 2.6 millimetres thick, just a little larger than a micro USB.
Unlike the classic USB, the USB-C is completely reversible and can be connected the right way up or upside down, which avoids damage caused by confusion.
If accompanied with the new USB 3.1 protocol, the USB-C input offers higher speed than older inputs, as well as more power.
USB-C is also compatible with the USB 2.0 standard, so it is backwards compatible, which is a crucial advantage for hardware manufacturers.
