The correct definition for bandwidth is:

Explanation:
Bandwidth is understood in multiple related ways in networking. It can refer to the channel’s capacity to carry data, typically expressed in bits per second, which is the practical throughput you can achieve. It can also refer to the width of the frequency spectrum used by the signal—the range of frequencies within a band—usually measured in hertz. In many discussions, the rate at which signals traverse a medium also influences how quickly information can be sent, affecting the effective throughput you observe. Because bandwidth covers both the data-rate capacity and the frequency-span aspects (and the speed-related influence on throughput in practice), all of these facets are correct, so the best answer is all of the above.
