Retrieved 18 April Packaging a software appliance as an installable live CD, or live ISO, can often be beneficial as a single image can run on both real hardware and on most types of virtual machines. Many Live CDs are used for data recovery, computer forensics , disk imaging , system recovery and malware removal. Some are designed to demonstrate or “test drive” a particular operating system usually Linux or another free or open source operating system.

IT administration breaks down to firewall, rescue, security, etc. The first Compact Disc drives on personal computers were generally much too slow to run complex operating systems; computers were not designed to boot from an optical disc. A Live CD allows users to run an operating system for any purpose without installing it or making any changes to the computer’s configuration.

It features easy mirror selection and “upgrading” of older images to the latest release.

DemoLinuxreleased inwas the first Linux distribution specially designed as a live CD. Puppy Linux and some other live CDs allow a configuration and added files to be written and used in later sessions.

All except the earliest digital computers are built with some form of minimal built-in loader, which loads a program or succession of programs from a storage medium, which then operate the computer. Retrieved 11 February This came out of necessity to avoid requiring the user to configure the system each time it boots and to make it easily usable by those who are new to the operating system.

Although early developers and users of distributions built on top of the Linux kernel so it could take advantage of cheap optical disks and rapidly declining prices of CD drives for personal computers, the Linux distribution CDs or “distros” were generally treated as a collection of installation packages that must first be permanently installed to hard disks on the target machine.

The Tails operating system is aimed at preserving privacy and anonymity of its users, allowing them to work with sensitive documents without leaving a record ueb a computer’s hard drive.

Retrieved from ” https: The Linuxcare bootable business cardfirst released inwas the first Live CD to focus on system administration, and the first to be distributed in the bootable business card form factor.

Software can be tested, or run for a particular single use, without interfering with system setup. Most of the popular Linux distributions now include a live CD variant, which in some cases is also the preferred installation medium.

Although some live CDs can load into memory to free the optical drive for other uses, loading the data from a CD-ROM is still slower than a typical hard drive boot, so this is rarely the default with large live CD images, but for smaller live CD images loading the filesystem directly into RAM can provide a significant performance boost, as RAM is much faster than a hard drive, and uses less power.

During live CD initialization, a user typically may resort to using one or more boot codes to change the booting behavior. This data may also include application and operating-system software, sometimes packaged and archived in compressed formats.

A read-only file systemsuch as on a CD-ROM has the drawback of being unable to save any current working data.

Many Linux based live CDs use a compressed filesystem image, often with the cloop compressed loopback driver, or squashfs compressed filesystem, generally doubling effective storage capacity, although slowing crs4 start up [ citation needed ].
