compression: Since data communication lines are so slow, it is important to use every possible scheme to use them efficiently. Compression schemes can reduce the amount of data that needs to be sent. The receiver fluffs the data back up to its original size. Compression schemes depend on the fact that most messages repeat words or phrases and use some letters of the alphabet more frequently than others. Compressors invent a scheme of short abbreviations for commonly used items. The GZIPOutputStream class appears to be broken. It does not compress or even produce uncompressed output. Other classes of interest include Deflater/Inflater, DeflaterOutputStream/InflaterInputStream, ZipEntry, ZipException, ZipFile, ZipInputStream, ZipOutputStream and Adler32 (for quick checksums);
