U disk works

U disk structure is basically composed of five parts: USB port, the main control chip, FLASH (flash memory), chip, PCB substrate, shell package. The USB port is responsible for connecting with the computer or other devices. The FLASH is similar to the memory in the computer. The main function is to save the information. Even if you leave the device or lose power, the data will not be lost. The PCB backplane provides a platform for processing data. It can also connect parts together; of course, the most important is the main control chip, which is equivalent to the brain of the entire U disk, responsible for coordinating and issuing management instructions, and allows the computer to identify U. plate.

There may be times when it is not convenient to carry the computer, but some files need to be carried around. At this time, the files can be copied to a USB flash drive. Its greatest feature is that it is portable. But it also has its limitations, such as low security, possible loss, etc., which will lead to leakage of information and information, so we must consider its security when using U disk, if U disk borrowed, we must pay attention to clean up in advance U disk files.
