Definitions for bandwidthˈbændˌwɪdθ, -ˌwɪtθ
Random House Webster's College Dictionary
the smallest range of electronic frequencies constituting a band, within which a particular signal can be transmitted without distortion.
Category: Telegraphy and Telephony
the transmission capacity of an electronic communications device.
Origin of bandwidth:
a data transmission rate; the maximum amount of information (bits/second) that can be transmitted along a channel
The width, usually measured in hertz, of a frequency band.
Of a signal, the width of the smallest frequency band within which the signal can fit
The rate of data flow in digital networks typically measured in bits per second
The capacity, energy or time required
I think it's a worthy project, but I just don't have the bandwidth right now.
The New Hacker's Dictionary
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.
Dictionary of Military and Associated Terms
The difference between the limiting frequencies of a continuous frequency band expressed in hertz (cycles per second). The term bandwidth is also loosely used to refer to the rate at which data can be transmitted over a given communications circuit. In the latter usage, bandwidth is usually expressed in either kilobits per second or megabits per second.
