Knoppix is a Linux distribution designed to be booted live from various storage media. Although many distributions now do this, it was notable as being one of the first. Originally developed in Germany by Klaus Knopper.

When starting a program it is loaded from the media and decompressed into a RAM drive. The decompression is transparent and on-the-fly.

Although Knoppix is primarily designed to be used as a Live media OS, it can also be installed on a hard disk like a typical operating system. Computers that support booting from various storage devices can load Knoppix from them.

Knoppix can be used to copy files easily from hard drives with inaccessible operating systems. To quickly and more safely use Linux software, the Live OS can be used instead of installing another OS. It mostly consists of free and open source software, but also includes proprietary programs.
