What does USB stand for in computing?

The correct answer, Universal Serial Bus, refers to a standard way to connect various devices to computers and other electronics. This specification defines the cables, connectors, and protocols for communication between devices, allowing them to connect and communicate effectively.

USB provides a universal standard that simplifies connectivity, enabling a wide range of devices, like keyboards, mice, storage devices, and smartphones, to connect through a single type of port. It supports data transfer, power supply, and device charging, making it fundamental in modern computing and electronics.

The other options do not accurately define the standard. "Universal Security Bus" and "User Service Block" are not recognized terms related to this technology, while "Unified Serial Bus" is close but not the official terminology; the correct term retains the designation "Serial," which is crucial in distinguishing it from other forms of bus technologies.
