What does USB stand for?

The correct answer is "Universal Serial Bus." This term defines a standard protocol used for connecting various devices to a computer, facilitating data transfer and power supply. The development of USB technology aimed to create a universal connection interface that would streamline the process of connecting peripherals, such as keyboards, mice, printers, and storage devices, to computers.

This naming reflects the key characteristics of USB: its universality and its design for serial data transmission, which sends data one bit at a time rather than all at once, like parallel connections do. Since its inception, USB has seen multiple versions with increased specifications, enhancing speed and capabilities while maintaining backward compatibility with older versions.

The other options represent common misunderstandings or variations that are not officially recognized in the context of USB technology. Understanding the correct term enhances clarity when discussing technical specifications and compatibility in modern computing contexts.
