What is a primary function of the Universal Serial Bus (USB)?

The primary function of the Universal Serial Bus (USB) is to enable wired communication for devices. USB serves as a standard protocol that allows various peripherals, such as keyboards, mice, printers, and external drives, to connect to a computer or other host devices. This connection facilitates the transfer of data and power between the devices. USB has evolved over the years from its earlier versions to newer standards that support higher data transfer rates and improved functionalities.

In this context, the other options, while related to technology, do not accurately represent the main purpose of USB. Wireless communication is not a function of USB, as it is fundamentally a wired connection standard. The ability to store large amounts of data is more associated with storage devices themselves rather than USB, which is a means of facilitating data transfer. Lastly, enhancing graphical processing pertains more to specific hardware components like GPUs rather than the function of a USB interface. Thus, ensuring clarity on these distinctions helps understand why enabling wired communication is the essence of USB's primary role.
