What does USB stand for?

• A. Universal Serial Bus
• B. Universal System Bus
• C. Unified Serial Bus
• D. Universal Shared Bus

Answer: (A)

USB stands for Universal Serial Bus. The word Universal signals broad compatibility across devices and platforms, which is the essence of USB as a universal interface. Serial means data is transmitted sequentially, one bit at a time, over a single channel, which describes how USB sends information rather than using multiple parallel wires. Bus refers to the shared communication pathway that connects peripherals to a host controller so many devices can connect to the same interface. This three-part naming is the standard description you’ll see in documentation, while the other phrasings don’t reflect USB’s actual purpose or how it operates.
