Which term refers to the speed at which data is transmitted?

• A. Latency
• B. Baud rate
• C. Bandwidth
• D. Throughput

Answer: (B)

Think of how fast the signaling on the line can change per second. That rate is captured by baud rate, which measures the number of symbol changes each second. If each symbol carries one bit, baud rate equals bits per second; if symbols carry multiple bits, the actual data rate can be higher, but the baud rate still reflects the speed of the signaling itself. The other terms describe different ideas: latency is the delay for data to reach its destination, bandwidth is the maximum capacity of the channel, and throughput is the actual amount of data successfully transferred over a period. So the term that directly describes the speed at which data is transmitted is baud rate.
