Universal ______ Bus is the common interface that allows communication between digital devices, transfers data, and can power devices. Fill blank with the correct word.

• A. Parallel
• B. Serial
• C. USB
• D. Ethernet

Answer: (B)

Universal Serial Bus is the standard interface that enables communication between digital devices, transfers data, and can power devices. The word to fill is Serial, forming Universal Serial Bus. Serial means data moves one bit at a time over a single pathway, which is how USB streams information between a computer and peripherals. This serial approach keeps wiring simple and reliable, and it can also supply power through the same connection. In contrast, a parallel bus would send multiple bits simultaneously over several wires, which USB does not do in its usual operation. Ethernet, on the other hand, is a networking technology designed for connecting devices to a network rather than providing a universal interface for direct device-to-device communication and power delivery.
