An interface that transmits or receives data one bit at a time is called a

• A. Parallel Interface
• B. Serial Interface
• C. USB Interface
• D. Network Interface

Answer: (B)

Sending data one bit at a time is serial transmission. In serial communication, bits are sent sequentially over a single line (with timing to keep bits aligned), which is simpler and cheaper for long distances or fewer wires. This is opposed to a parallel interface, which carries multiple bits at once over many wires but requires tightly synchronized timing and more hardware. While USB is a common serial interface, the general term that matches the description is serial interface. A network interface, on the other hand, describes connectivity to a network rather than how data bits are transferred.
