"A bootable business card, or BBC, is a complete operating system contained on a business-card-sized CD-ROM. These mighty mites normally focus on utility rather than usability. They are usually self-contained rescue and recovery tools which can be used to retrieve information or modify damaged configurations on machines with non-functional operating systems installed. They require no installation, running live from CD-ROM. They don't care what operating system is present on the hard
drive. And they do nothing to modify the contents of the drive unless you explicitly choose to do so.
"Because a business card CD-ROM can only hold about 50 MB of software, the emphasis is on keeping things small. You won't find the typical debates regarding KDE versus GNOME on BBCs. Both of those desktop solutions require far too much disk space to be useful in this arena. Instead, you can expect to employ lightweight window managers like Fluxbox or Blackbox..."
