In electrical systems, what is the name given to a conductor that transmits serial data?

• A. Power lead
• B. Signal line
• C. Data bus
• D. Control wire

Answer: (C)

The key idea is recognizing the path that carries data between components. The data bus represents the channel through which the actual data payload moves, and it can be used for serial or parallel transmission depending on the system’s design. A power lead is meant to supply electrical power, not carry data. A signal line is a general term for a conductor that carries signals but doesn’t specify data payload transfer. A control wire carries control information to manage operations, not the data itself. So the conductor that transmits serial data is best described as the data bus.
