Linux Installation CDs vs. Linux Live CDs by Clyde Boom

You need to learn how to use Linux. And the best way to get Linux training is to work with it and get real, practical Linux experience. There are lots of different ways to get Linux, and lots of different versions of Linux to choose from!

You can get a version of Linux, also known as a Linux distribution (or distro for short), on CD or DVD. You can also download a Linux ISO file and burn it to CD or DVD yourself.

Linux Tip: If you decide to download Linux as a Linux ISO file, keep in mind that these files are very large. Linux CD ISO files are about 700 MB and Linux DVD ISO files are about 4 GB (almost six times the size of a CD!). Therefore, only download Linux if you have high-speed Internet access.

Linux Tip: You can do an Internet search for "list of linux cds" or "list of linux dvds" and buy the Linux OS and have it delivered to you by mail very cheaply.

Some Linux distros are available as "installation" versions and some are available as "live" versions - and some are available as both!

An installation version of Linux may be on just a one CD/DVD or it may require more than one. However, a Linux live CD or a Linux live DVD version consists of just a single CD or DVD.

Linux Installation Versions

You boot a computer system with a Linux installation CD/DVD to run the Linux installation routine and install Linux on a system. This could be a system that doesn't have an operating system on it - or it could be one that does have an operating system on it, such as the Windows operating system.

If you install Linux on Windows, you create a "dual boot" (Linux and Windows) system. Then after the Linux installation, you can either boot the system into Windows or boot it into Linux, but not both at the same time.

When you install Linux from CD or DVD onto a computer system, you run the Linux installation routine and do several steps to put the Linux OS and Linux software programs on the hard disk in a system permanently, although you can remove Linux later if you need to.

After you install Linux, you boot to Linux from the hard disk in the system. At this point, the Linux desktop appears and you can do a few simple steps to open a terminal emulation window. This allows you to go to the Linux command line so you can run Linux commands - the best way to learn how to use Linux.

Linux Live Versions

Linux live CDs or DVDs are used to run Linux "live", for as long as the power is turned on.

To run a Linux live version, you set your system up to boot from the live CD or DVD. Then you start your system with the Linux live CD/DVD in your drive. No installation is required!

After you boot with a Linux live CD/DVD, the entire Linux OS (operating system) boots and runs automatically. At this point, you see a Linux desktop on the screen and you can run Linux software programs.

At the Linux desktop, you can also do the steps to open a terminal emulation window. This allows you to work at the Linux command line as the root user and run Linux commands. And learning to run Linux commands is the best way to learn how to use Linux and do Linux system administration.
