General Information

Linux is an operating system that freely releases its source code to anyone that wishes to use the Linux Kernal. When people say "Linux" they are usually talking about a specific Linux distribution. If you are talking about just the operating system the technical term is Linux kernel. A Linux distribution is considered to be the Linux kernel and a group of applications that have been put together in an easy installation package. There are a wide variety of Linux distributions, however, there are some common unifying elements. Linux tends to be lightweight, it is customizable, and Linux has a supportive user community because it is user-run.
 

All Linux Distributions Have
  • Standard Operating System
     
  • X Windows System (Graphical User Interface)
     
  • One or more Graphical Desktops (GNOME and KDE are the most common)
     
  • Collection of Applications

The collection of applications for Linux are program software ready to use. The applications also come with documentation and source code which allows the user to tell the computer what to do. The collection can be very large which means the distribution could come on multiple CDs or on a DVD.
 

Linux Distributions

Some of the distributions mentioned are Live CDs. A Live CD allows you to run the Linux kernel without installing it on the hard drive. These distributions are popular for users who want to try it out before installing it. Most Linux distributions are free for download. Some are commercial and can be sold for profit, however, these must still be in source code and can be copied and redistributed.
