A wire that carries serial data is typically known as what?

• A. Serial line
• B. Control conductor
• C. Data bus
• D. Signal wire

Answer: (C)

The key idea here is distinguishing between a serial data path and a data bus. When data is sent one bit at a time over a single wire, that wire is best called a serial line or data line—a dedicated channel for serial communication. A data bus, on the other hand, is a bundle of multiple conductors that move data in parallel between components; it represents a group path, not just a single conductor. So a single wire carrying serial data is typically described as a serial line, while a data bus refers to the multi-wire pathway used for parallel data transfer. Some contexts or older usages might use “bus” more loosely to mean a data pathway, but the precise term for a lone serial conductor is serial line.
