Linux can compress files into a variety of formats and uncompress them. The most popular format is GNU Zip (gzip), whose compressed files are named with the .gz suffix. Other commonly found formats are classic Unix compression (.Z suffix), bzip2 compression (.bz2 suffix) and Zip files from Windows systems (.zip suffix).
A related technology involves converting binary files into textual formats, so they can (say) be transmitted within an email message. Nowadays this is done automatically with attachments and MIME tools, but we’ll cover the older uuencode and uudecode programs, which do still get used.
If you come across a format we don’t cover, such as Macintosh hqx/sit files, Arc, Zoo, and others, you can learn more at http://www.faqs.org/faqs/compression-faq/part1/section-2.html and http://www-106.ibm.com/developerworks/library/l-lw-comp.html
