**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 is the power at the frequency and 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.
