The U disk is the abbreviation of the USB Disk, and the USB disk is just the homophonic name of the U disk. USB is an acronym for Universal Serial Bus. In general terms, USB is one of the types of interfaces that peripheral devices connect to a host computer. In addition to the USB interface, there are interfaces such as a parallel bus. However, the USB interface has a great advantage, making it very popular in this field, that is, devices with such interfaces can be plug and play on the computer (plug and play sometimes called hot plug).
