Linux is an operating system, a large piece of software that manages a computer. It is similar to Microsoft Windows®, but it is entirely free. The accurate name is GNU/Linux but "Linux" is used more often.

Linux is not one company's product, but a number of companies and groups of people contribute to it. In fact, the GNU/Linux system is a core component, which is branched off into many different products. They are called distributions.

Distributions change the appearance and function of Linux completely. They range from large, fully supported complete systems (developed by companies) to lightweight ones that fit on a USB memory stick or run on old computers (often developed by volunteers).
A prominent, complete and friendly distribution to step into GNU/Linux is Ubuntu.

GNU/Linux is no harder to use than Windows®, and has many more capabilities. It just takes a dozen minutes to get familiar with a distribution like Ubuntu or Fedora, which come in with many programs installed. If you need commercial-quality software to work with business documents, internet/networking, or multimedia and graphics, it's there right out of the box. Want more than that? Linux can do – there are many hundreds of free, high quality applications you can find, install and uninstall neatly and easily

A tip from our Webmaster

Web pages, of course, are primarily designed to be viewed on screen.  That’s
(almost) what the Web’s all about.  But sometimes you need to print off
hardcopy.  And the results often range from disappointing to unusable.

 What can you do?

     1.  If you’re lucky, the designers of the Web site whose page you want to
         print thought ahead and anticipated your needs.  Look for a link or a
         linkable icon or graphic that says something like “print­friendly” or “print
         this page”, usually near the very top or bottom, or both, of the page.
         Click that link and a new page should load in your browser that shows a
         more “vanilla” kind of presentation, without navigation links, background
         graphics and the like.  This is the text­only or mostly­text page that you
         should print.

     2.  If you don’t find an obvious print­friendly kind of option, be sure to try
         “print preview” (usually under File on your main menu bar) in your
         browser.    You may mercifully find that the Web designers are forward­
         thinking and have automatically created a printer­friendly alternative view
         for you that requires no further action on your part.  If it looks right in
         your print preview, you should be able to print directly.

     3.  But what if it doesn’t look right at all when you do a Print Preview?  Most
         common are pages that are so wide that the right portion does not show
         up at all.  Try setting your print output to Landscape in this case.  You can
         usually do this by first selecting the File | Print menu option, then in the
         Print dialog box that appears, choose Landscape.  Or set Landscape from
         the Print Preview screen.  The Landscape setting might be hidden under a
         Properties button on the Print dialog box, so don’t give up looking if you
         don’t see it immediately.

     4.  You may also want to suppress or enable background colors and graphics
         while printing to get readable hardcopy.  This might be a little more
         challenging to find.  On Microsoft Internet Explorer v6 (by far the most
         commonly used browser by our customers), from the main browser menu,
         choose Tools | Internet Options | Advanced, then scroll down to Printing,
         where you will find that you can check or uncheck a box for “Print
         Background Colors and Images”.  For Firefox, go to File | Page Setup to
         find a similar “Print Backgrounds (colors and images)” checkbox.

     5.  If you get really desperate, you can select areas on the Web page that
         you want to print, and copy and paste that material into an open window
         in your text editor (like Windows Notepad) or word processor. 
         You will probably lose all the original formatting,
         but in some cases you can get a result that is better than printing the page itself. 
         And you might send off a message to the site’s Webmaster,
         suggesting that they implement a CSS
         print­only stylesheet, or some otherwise print­friendly solution!
