Open+Source

Open source means free of cost and free of licenses. The source code is open to anyone who has the ability and the drive to tackle it. The source code is the series of commands that make the software do what it is supposed to do. Most of the software we purchase on a disc or by download are not open source, which means only the companies who create them and make them (and the folks they designate) have access to the code. The thinking behind the open source concept is that the application will become more useful (because more users and developers are working on it worldwide as opposed to a few developers at a company) and more bug free (fewer viruses because there are more minds working on keeping the bugs at bay).

Some open source applications/software are
 * Linux operating system
 * Moodle
 * Mozilla
 * PERL (Web-scripting program)
 * PNG (graphics file format; it's the format your MacBook saves screenshots to)
 * Wikipedia

Sites that serve as repositories of open source code are
 * @http://sourceforge.net/
