Expansion: U disk, full name "USB flash drive", English name "USB flash drive". It is a miniature large-capacity mobile storage product, with USB interface, without physical drive, and can be connected with a computer through USB interface to realize plug and play.
The name of USB flash drive comes from a new storage device produced by Netac, called USB flash drive, which is connected through USB interface. After the USB interface is connected to the computer host, you can exchange the data of the U disk with the computer. However, the equipment with similar technology produced later, because Netac has registered the patent, can no longer be called "USB flash drive", but changed its name to "USB flash drive".
