The name of compact discs that contain an operating system and often other programs that are capable of running on the computer without having to be installed or the need of a hard disk drive. Typically these CDs are used as a way for a user to experience an operating system without having to go through the hassle of erasing their hard disk drive and installing it. For example, many Linux distributions are available in LiveCD format allowing Microsoft Windows users to experiment with Linux without having to erase Windows.
Many LiveCDs are saved as an ISO image, which allows a user to easily create a CD directly from the ISO without having to manually setup the CD. An example of a LiveCD is the Anonym.OS LiveCD, an OpenBSD OS that has been designed to help keep a user anonymous while on a network and the Internet.
