A LiveCD is an operating system (usually containing other software as well) stored on a bootable CD-ROM or DVD-ROM that can be executed from it, without installation into permanent memory, such as a hard drive. The system returns to its previous OS when the LiveCD is ejected and the computer is rebooted. It does this by placing the files which typically would be stored on a hard drive, into temporary memory, such as a ram disk. This however does cut down on the RAM available to applications, reducing performance somewhat. Download high resolution version (1024x768, 196 KB) Screenshot of Gnoppix 0. ...

Most LiveCDs contain a system based on the GNU system and the Linux kernel, but there are also LiveCDs based on other operating systems, such as Mac OS, Mac OS X, BeOS, FreeBSD, Minix, NetBSD, Plan 9 or Microsoft Windows, though the legal status of LiveCDs based on Windows code is dubious. The first OS to support LiveCD operations appears to have been Mac OS 7 on a CD and any other user-created Macintosh CD with a System Folder, which could be brought to a full desktop from a CD-ROM, in 1991.

The syslinux utility is used to boot Linux based LiveCDs as well as Linux floppies. On a PC, a bootable CD generally conforms to the El Torito specification which treats a special file on the disc (possibly hidden) as a floppy diskette image. Many Linux based LiveCDs use a compressed filesystem image, often with the cloop compressed loopback driver, generally doubling effective storage capacity, although slowing application start up. The resulting environment can be quite rich: typical Knoppix systems include around 1,200 separate software packages. The SYSLINUX Project covers a suite of lightweight bootloaders, for starting up computers in the Linux operating system. ...

LiveCDs have a reputation for supporting advanced Auto-configuration and Plug-and-play functionality. This is necessary so as to avoid requiring the user to configure the system each time it boots, and to make them easily usable by those who are new to the operating system. A LiveCD is an operating system (usually containing other software as well) stored on a bootable CD-ROM that can be executed from it, without installation on a hard drive. ...
Auto-configuration is the automatic configuration of devices without manual intervention, without any need for software configuration programs or jumpers. ...
Plug and Play is a term used in the computer field to describe a computers ability to have new devices, normally peripherals, added to it without having to restart the computer. ...
Mini-LiveCDs A Mini-LiveCD, also known as a bootable business card, is a LiveCD small enough to fit on a CD-ROM that is the size and shape of a business card. Mini-LiveCDs are able to hold about 50 MB, or 100 MB under compression. Damn Small Linux (DSL) is an example of a rich Mini-LiveCD operating system that fits onto a 50 MB CD. Includes scripts to optionally install it to bootable USB key (flash distro) or hard disk. A bootable business card is a CD-ROM that has been cut, pressed, or molded to the size and shape of a business card (designed to fit in your wallet or pocket). ...

Emulation There are number of emulators on the market that can be used to try a LiveCD without the need to burn it to a CD or boot it on the computer. The most widely supported i386 emulator is VMware. Others include Qemu, PearPC and Bochs which can all also emulate the x86 and/or PowerPC platforms, although due to their software emulation methods, they are slower than the hardware alternatives. Another commercial emulator is VirtualPC. A CD-R (Compact Disc-Recordable) is a thin (1. ...
