Now both the compressed quote and the index and saved, and a small amount of space is saved as well.  while very little is actually saved in this case, the compression ration is fairly high, which means the a complete speech or even a book of speeches will probably compress very well.<ref>http://computer.howstuffworks.com/file-compression1.htm</ref><br />

This is not the full extent of compression, however.  While a human might not want to take hand-processed compression any farther, a computer has no difficulty in finding other patterns within words and indexing them as well.  In this single quote, such an attempt would not be very profitable, but when a larger block of information is processed, this will become much more useful.<ref>http://computer.howstuffworks.com/file-compression2.htm</ref>
