signal-to-noise ratio
1. (SNR, "s/n ratio", "s:n ratio") "Signal"
refers to useful information conveyed by some communications
medium, and "noise" to anything else on that medium. The
ratio of these is usually expressed logarithmically, in
decibels.
2. The term is often applied to Usenet
newsgroups though figures are never given. Here it is quite
common to have more noise (inappropriate postings which
contribute nothing) than signal (relevant, useful or
interesting postings). The signal gets lost in the noise
when it becomes too much effort to try to find interesting
articles among all the crud. Posting "noise" is probably the
worst breach of netiquette and is a waste of bandwidth.

From Jargon File (4.3.1, 29 Jun 2001) : [ jargon ]
signal-to-noise ratio [from analog electronics] n. Used by hackers in a
generalization of its technical meaning. `Signal' refers to useful
information conveyed by some communications medium, and `noise' to
anything else on that medium. Hence a low ratio implies that it is not
worth paying attention to the medium in question. Figures for such
metaphorical ratios are never given. The term is most often applied to
Usenet newsgroups during flame wars. Compare bandwidth. See also
coefficient of X, lost in the noise.
