USB interfaces are widely recognized for their versatility, and a significant characteristic is their ability to handle both data transfer and power supply within a single connection. This dual functionality allows for a wide variety of applications, from connecting peripherals like keyboards and mice to charging devices such as smartphones and tablets.

This characteristic enhances usability and convenience, as users can rely on a single cable for both powering devices and transmitting data. The seamless integration of these two functions is a fundamental aspect of USB technology, facilitating a broad ecosystem of devices and accessories designed to work together efficiently.

The other options imply more restrictive uses for USB technology. For example, limiting USB to only audio devices does not capture the full scope of its capabilities, as USB can connect a variety of devices beyond just audio. Similarly, characterizing USB as primarily used for wireless communication is inaccurate, as USB is fundamentally a wired interface. Lastly, USB's exclusivity to network connectivity is also a misconception, since many USB devices serve non-network purposes, such as storage and power supply, thus highlighting the multifaceted nature of USB interfaces.
