2. Convenient to carry. USB devices are mostly known for being "small, light, and thin", making it convenient for half households to carry a large amount of data with them.

3. Unified standards. The common ones are hard drives with IDE interfaces, mouse and keyboard with serial ports, and printer scanners with parallel ports. However, with USB, these application peripherals can all be connected to personal computers using the same standard, resulting in USB hard drives, USB mice, USB printers, and so on.

4. It can connect multiple devices, and USB often has multiple interfaces on personal computers, which can connect multiple devices simultaneously. If a USB with four ports is connected.
