For example, printers can only be connected to LPTport, modems can only be connected to RS232, mouse and keyboard can only be connected to PS/2, etc. The complicated interface system, plus the driver must be installed The restriction that the program can only be used after rebooting will inevitably cause troubles for users. Therefore, it becomes an inevitable trend to create a unified external transmission interface that supports hot plugging, so the commonly used Universal Serial Bus (USB) was created.

There are many types of common serial buses as technology evolves, but basically they all include at least one shielded iron shell, at least one insulating plastic inside the shielded iron shell, and multiple parallel arrays arranged on the insulating plastic.
