The difference between the highest and lowest frequencies in a band, which determines circuit capacity, is called what?

• A. Bandwidth
• B. Latency
• C. Throughput
• D. Spectrum

Answer: (A)

Bandwidth is the width of the frequency range a channel can carry, defined as the difference between its highest and lowest frequencies. This width sets how much information can be transmitted per second, i.e., the circuit’s capacity, because a larger band can support more signal variations and higher data rates. In practical terms, wider bandwidth means more symbols per second and, with appropriate modulation, more bits per symbol, up to limits set by noise. Latency is the time delay for a signal to travel, not the frequency span. Throughput is the actual data rate achieved, which can be lower than the theoretical capacity due to overhead and other factors. Spectrum refers to the overall range of frequencies allocated or used, not the specific width of a single channel.
