USB Port: It is a serial bus standard for connecting computer systems with external devices, as well as a technical specification for input/output interfaces. 2. Application: It is used in information communication products such as personal computers and mobile devices, and has been extended to other related fields such as photographic equipment, digital TVs, and game consoles. Advantages of USB ports include: 1. Hot-swappable: Users can connect USB devices while the computer is running without the need to shut down or restart. 2.
