U disk, full name USB flash drive, English name USBflashdrive. It is a micro high-capacity mobile storage product that uses a USB interface and does not require a physical drive. It is connected to the computer through the USB interface to achieve plug-and-play. The name USB flash drive originally came from a new type of storage device produced by Netac Technology, called USB flash drive, which is connected using a USB interface. After the U disk is connected to the USB interface of the computer, the data in the U disk can be exchanged with the computer. Since Netac has registered a patent for the equipment with similar technology produced later, it can no longer be called a USB flash drive, but is renamed a homophonic USB flash drive.
