theory A measure of the disorder of a system. Systems tend
to go from a state of order (low entropy) to a state of
maximum disorder (high entropy).
The entropy of a system is related to the amount of
information it contains. A highly ordered system can be
described using fewer bits of information than a disordered
one. For example, a string containing one million "0"s can be
described using run-length encoding as [("0", 1000000)]
whereas a string of random symbols (e.g. bits, or characters)
will be much harder, if not impossible, to compress in this
