What does USB stand for?

• A. Uniform System Bus
• B. Universal Serial Bus
• C. Universal Simple Bus
• D. Unique Serial Bus

Answer: (B)

USB stands for Universal Serial Bus, a standard for connecting peripherals to a computer. Universal means it’s designed to work with a wide range of devices and manufacturers. Serial means data is sent one bit after another in a single data stream, rather than across many wires at once. Bus refers to the shared communication pathway that multiple devices can use to talk to the host computer. This combination explains why USB became the common connection for keyboards, mice, printers, drives, and many other devices, and why newer USB versions keep the same name while improving speed and power delivery. The other options don’t reflect the established name of this standard.
