Bandwidth is

• A. Data throughput
• B. Latency measure
• C. Modulation quality
• D. Signal frequency

Answer: (A)

Bandwidth is the amount of data that can be transmitted over a channel in a given time—the data transfer capacity. In most networking contexts, this is treated as data throughput, the actual rate at which data moves, typically measured in bits per second (bps) or its multiples. Latency measures how long a bit takes to travel from sender to receiver, not how much data can be sent per second. Modulation quality affects how cleanly the signal is encoded and decoded, which influences error rates, but not the channel’s capacity itself. Signal frequency refers to the carrier frequency, whereas bandwidth describes the width of the frequency range available for carrying signals, which in turn limits potential data rate. So the best fit is data throughput.
