Although the current portable WIFI (Xiaomi WIFI, 360WIFI) looks like a U disk in shape and material, they are completely different from the U disk. Portable WIFI has a built-in wireless USB network card chip, which is not available on ordinary U disk. It can only store files, so the USB flash drive cannot be turned into portable WIFI.
U disk, full name of USB flash drive, English name of USB flash drive. It is a miniature high-capacity mobile storage product, which uses USB interface and does not need physical drive. Connect with computer through USB interface to realize plug and play.
The name of USB flash drive comes from a new storage device produced by Netac Technology, which is called "USB flash drive" and is connected by USB interface. After the USB flash drive is connected to the USB interface of the computer, the data of the USB flash drive can be exchanged 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". Later, the name U disk was widely known because it was easy to remember, and it was one of the mobile storage devices. There are many USB flash drives that support multi-ports, that is, three-way USB flash drives (USB computer port, iOS Apple interface, Android interface).
