| 62766 | 2002-07-15 06:16:00 | Winzip uses compression. Simply put (courtesy of the web) Compression uses what is known as an algorithm (any set of instructions to be followed in order) to take a data file as input and make sure the output is a much smaller file. As an example, take a string of characters - cheese and ham and more cheese How else could this string of characters be represented? Well, we could make up a code. Notice the words "and" and "cheese" appear twice in the string, we could encode (compress) the string as follows: b="cheese" c="and" to get: b c ham c more b If this is applied to a whole file only concentrating on frequently used code or text, the file could be made considerably smaller. This is an example of a fixed length code. |
