LiveCD

A Live CD or Live DVD, more generically Live Distro, sometimes being called a Live CD or Standalone CD, is an operating system stored on removable media, traditionally a CD or DVD (hence their names), which can be run directly on a computer.

Usually a Live CD comes with a couple of applications. Some Live CDs include a tool that allows you to install them to your hard drive. Another feature is that usually no changes are made to the computer used.

To use a Live CD, you need to obtain one (many of them freely distribute an ISO image that can be downloaded from the Internet and burn to a disc) and configure the computer to boot from the drive, then reboot the computer with the disc in the drive, which will start the Live CD manually.

Features

Most use an operating system based on the Linux kernel, but other systems such as ReactOS, BeOS, FreeBSD, Minix, Solaris, OS/2 or even Microsoft Windows are also used (however, distributing a Live CD of the latter It's totally legal).

One of the biggest drawbacks of this system is the misuse of a large amount of RAM (256 MB is more than enough and there are distributions that work perfectly with 128 MB), a part for regular use and another to work as the virtual disk of the system. At startup, it can be given different parameters to adapt the system to the computer, such as the screen resolution or to activate or deactivate the automatic search for certain hardware.

A Live CD does not require installation, so there is no need to touch your hard drive or follow complicated procedures. In addition, the data, partitions or operating systems on the hard drive are not lost. Even so, some Live CDs have an installer to be able to be installed, being able to know the real performance of the distro, since the transfer speed of the drives (CD/DVD) is much lower than that of hard drives. (vr).

Live CD Linux

Some Linux distributions are Live CDs. The first Linux Live CD was Yggdrasil Linux in 1995, although it was unsuccessful. Later DemoLinux (year 2000) emerged.

The rise of this modality of Linux began around 2003 with the German distribution of Knoppix, based, in turn, on the Debian software distribution. One of the improvements of this method was the cloop compression, this allowed to exceed the 650-700 MB of the CD (the loop driver was used) and manage to introduce up to 2 GB. The Spanish Hispalinux association has popularized its own system, called Metadistros, fundamental in the Linex and Guadalinex distributions.

The Syslinux Project covers bootloaders for floppy disks (Syslinux), network boot (Pxelinux), and bootable CD-ROMs under the name "El Torito", also called Live CD (Isolinux).

The Syslinux utility is most commonly used on most Live CDs as well as floppy disks. On a computer a bootable CD conforms to the specification called El Torito which creates a special file on the disk (probably hidden), in the same way on a floppy disk. The image of this file system is normally compressed with cloop.

They are distributions easy to find, since some computer magazines decide on this type of distribution to reach the Windows user. They usually have an advanced hardware recognition, also the result of the latest kernel versions that they usually have.

In short, Live CD distributions try to bring Linux to users of other operating systems
