Is a USP an input or output device?

A USP, or Unique Selling Proposition, is not an input or output device; rather, it is a marketing concept that defines what makes a product or service distinct and appealing to customers. It highlights the unique benefits or features that differentiate it from competitors. In contrast, input devices (like keyboards and mice) allow users to provide data to a computer, while output devices (like monitors and printers) present data from a computer to the user.
