Knoppix based on Debian
KNOPPIX ( KNOP-iks) is an operating system based on Debian designed to be run directly from a CD / DVD (Live CD) or a USB flash drive (Live USB), one of the first live operating system distributions (just after Yggdrasil Linux). Knoppix was developed by, and named after, Linux consultant Klaus Knopper. When starting a program, it is loaded from the removable medium 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 CD, it can also be installed on a hard disk like a typical operating system. Computers that support booting from USB devices can load KNOPPIX from a live USB flash drive or memory card.
There are two main editions: the traditional compact-disc (700 megabytes) edition and the DVD (4.7 gigabytes) "Maxi" edition. The CD edition had not been updated since June 2013 until recently. As of version 9.1, CD images are being released once again. Each main edition has two language-specific editions: English and German.
KNOPPIX mostly consists of free and open source software, but also includes some proprietary software, as long as it fulfills certain conditions.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 CD can be used instead of installing another OS.Popularity
Knoppix was one of the first Live CD Linux distributions to gain popularity. There are several factors that contribute to the popularity of Knoppix:Knoppix was one of the first Live CDs available, and is known as the "original" Debian-based Live CD
Its extensive hardware detection allows most systems to start Knoppix without any configuration
Its ability to automatically connect to most kinds of networks
Its utilities for system repair and troubleshootingKnoppix works on a fairly large number of PCs or laptops, but not all. The automatic hardware detection cannot cope with all hardware, and sometimes the drivers used will not be optimal. Knoppix has difficulty recognizing some cards made before 1998, or motherboards with a BIOS made before 2002. (In some cases, manual configuration with codes entered at boot time can overcome problems with automatic detection.)If a PC does not have enough RAM to run KDE and other included programs, the legacy Knoppix (earlier than 6.0) boots up a very limited Tab Window Manager (twm) session instead. The only window running in the twm session by default is xterm.
