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.
