What is the standard unit to express bandwidth?

Explanation:
Bandwidth is a measure of the width of the frequency range a system can carry. Because it deals with frequency, the natural unit is hertz, which means cycles per second. In radio practice you’ll see bandwidth expressed in kilohertz or megahertz, depending on the size of the band. For example, if a channel spans from 100.0 MHz to 100.2 MHz, its bandwidth is 0.2 MHz (200 kHz), which is 200,000 Hz. The other units listed describe time, money, and light, not frequency width, so they don’t fit. Hence, hertz is the standard unit for bandwidth.
