U disk integrates hard disk storage technology, flash memory technology and universal serial bus technology. The USB port is connected to the computer and is a data input/output channel; The main control chip enables the computer to recognize that the U disk is a removable disk, which is the "brain" of the U disk.
Flash memory chips can store data, unlike computer memory, even if power is cut off, data will not be lost; The PCB backplane connects all components together to provide a data processing platform.
Precautions:
U disk is a kind of miniature and large-capacity mobile storage product, which has a USB interface and can be connected with a computer through the USB interface to realize plug and play. The name of U disk comes from a new storage device produced by Netac Technology, called "USB", which is connected through USB interface.
Connect the USB mobile U disk to the USB interface of the computer and exchange data with the computer. After the production of similar technical equipment, due to the patent registration of Netac, it can no longer be called "usb" but changed its name to "U disk". Later, the name of U disk was widely known because of its simplicity, and it was a mobile storage device.
