redundancy - Free On-line Dictionary of Computing (26 May 2007) :
redundancy
1. <architecture, parallel> The provision of multiple
interchangeable components to perform a single function in
order to provide resilience (to cope with failures and
errors). Redundancy normally applies primarily to hardware.
For example, a cluster may contain two or three computers
doing the same job. They could all be active all the time
thus giving extra performance through parallel processing
and load balancing; one could be active and the others
simply monitoring its activity so as to be ready to take over
if it failed ("warm standby"); the "spares" could be kept
turned off and only switched on when needed ("cold standby").
Another common form of hardware redundancy is disk mirroring
.
Redundancy can also be used to detect and recover from errors,
either in hardware or software. A well known example of this
is the cyclic redundancy check which adds redundant data to
a block in order to detect corruption during storage or
transmission. If the cost of errors is high enough, e.g. in a
safety-critical system, redundancy may be used in both
hardware AND software with three separate computers programmed
by three separate teams ("triple redundancy") and some system
to check that they all produce the same answer, or some kind
of majority voting system.
2. <communications> The proportion of a message's gross
information content that can be eliminated without losing
essential information.
Technically, redundancy is one minus the ratio of the actual
uncertainty to the maximum uncertainty. This is the fraction
of the structure of the message which is determined not by the
choice of the sender, but rather by the accepted statistical
rules governing the choice of the symbols in question.

redundancy - Bouvier's Law Dictionary, Revised 6th Ed (1856) :
REDUNDANCY. Matter introduced in an answer, or pleading, which is foreign to
the bill or articles.
2. In the case of Dysart v. Dysart, 3 Curt. Ecc. R. 543, in giving the
judgment of the court, Dr. Lushington says: "It may not, perhaps, be easy to
define the meaning of this term [redundant] in a short sentence, but the
true meaning I take to be this: the respondent is not to insert in his
answer any matter foreign to the articles he is called upon to answer,
although such matter may be admissible in a plea; but he may, in his answer,
plead matter by way of explanation pertinent to the articles, even if such
matter shall be solely in his own knowledge and to such extent incapable of
proof; or he may state matter which can be substantiated by witnesses; but
in this latter instance, if such matter be introduced into the answer and
not afterwards put in the plea or proved, the court will give no weight or
credence to such part of the answer."
3. A material distinction is to be observed between redundancy in the
allegation and redundancy in the proof. In the former case, a variance
between the allegation and the proof will be fatal if the redundant
allegations are descriptive of that which is essential. But in the latter
case, redundancy cannot vitiate, because more is proved than is alleged,
unless the matter superfluously proved goes to contradict some essential
part of the allegation. 1 Greenl. Ev. Sec. 67; 1 Stark. Ev. 401.
