What are ISO and RAR Files?

http://live.pirillo.com/ – RAR, ZIP, ARC, ISO: they’re all different types of compressed files floating around the internet. LesterMorrow asks "what are ISO and RAR files and how do I use them?"

ISO and RAR files are archives. The most common type of archive files people run into are ZIP files, but there are other formats, including tar.gz, hqx, and 7z.

Most archived files compress the information they contain and make it easier to store and transfer over a network.

ISO files are disk images, in most cases CD or DVD, which contain an uncompressed image that you can burn with a burning program, such a Roxio Easy Media Creator.
