Cryotanks and cryogenics can be seen in many sci-fi movies, but they are still currently undeveloped. All that needs to
Prefix code to minimizing the entropy.) This is a form of lossless data compression based on entropy encoding. Some codes mark the end of a code word with a special "comma" symbol, different from normal data. This is somewhat analogous to the spaces between words in a sentence; they mark where one word ends and another begins. If every code word ends in a comma, and the comma does not appear elsewhere in a code word, the code is automatically prefix-free. However, modern communication systems send everything as sequences of "1" and "0" – adding a third symbol would be expensive, and
