Bandwidth

[Sarah]

The difference between the highest and lowest frequencies of a transmission channel (the width of its allocated band of frequencies). The term is often used erroneously to mean {data rate} or capacity - the amount of {data} that is, or can be, sent through a given communications circuit per second.

[Vania]

The width, in [Hertz], of the pass-band of any equipment that can process information. Most computer data transfer works at base-band (unlike radio transmitters, which usually operate on some higher wave band) so the bandwidth is usually equal to its [baud] rate.

[Jessica]

The speed at which a person can comprehend. A measure of mental agility.

[Dianne]

A measure of how fat a band is. The greater the fatness, the greater the bandwidth.

[Donald Trump]

Referring to the size of ones pant size.

[Tina]

ability (or lack of ability) to complete work given the available resources (people, time, money, etc.)

[Lanell]

The width, usually measured in hertz, of a frequency band.

[IsobelHaups]

The rate of data flow in digital networks typically measured in bits per second

1. [common] Used by hackers (in a generalization of its technical
   meaning) as the volume of information per unit time that a computer,
   person, or transmission medium can handle. “Those are amazing
   graphics, but I missed some of the detail — not enough bandwidth, I
   guess.” Compare low-bandwidth; see also
   brainwidth. This generalized usage began to go
   mainstream after the Internet population explosion of 1993-1994. 2. Attention span. 3. On Usenet, a measure of network capacity
   that is often wasted by people complaining about how items posted by others
   are a waste of bandwidth.

[Gonzalesalix 0]

Of a signal, the width of the smallest frequency band within which the signal can fit

[Dave Paprocki]

The capacity, energy or time required
