**1**. The range of frequencies over which a given device is designed to operate within specified limits. **2**. The differences between half-power points, i.e., the frequencies at which the power drops to half the peak power (3 dB). **3**. The **effective bandwidth** is

where *p*(*f*) is the power at the frequency *f* and *p*_{max} is the maximum power. It is the width of a boxcar with the same total power and the same peak power. **4**. The rate at which a computer resource can carry (accept or deliver) data. Usually expressed in bytes per second or bits per second.
