Open Source

[Gregory]

When a software program is open source, it means the programs source code is freely available to the public. Unlike commercial software, open source programs can be modified and distributed by anyone and are often developed as a community rather than by a single organization. For this reason, the phrase open source community is commonly used to describe the developer of open source software development projects.
Since the source code of an open source program can be modified by anyone, it makes sense that the software is also free to download and use. The terms of use are often defined by the GNU General Public License, which serves as the software license agreement (SLA) for many open source programs. Open source software development projects are often funded by donors with an interest in the project, by user donations, or through advertisements. Some developers also generate revenue by selling documentation and help manuals for the software. Other projects are funded by no more than a collective desire of developers to create a great program.
Since open source software is free to use, there is typically no technical support included with the software. Instead, users may need to rely on Web forums and user discussions to report bugs or get answers to their questions. Fortunately, the most popular open source programs have an abundance of helpful resources available on the Web. Some of the most well-known open source projects include the Linux operating system, the Mozilla Firefox Web browser, and the OpenOffice.org productivity suite. Each of these projects have been developed by a community of developers and have gained levels of popularity that rival their commercial counterparts.
Open source software can be a cost-effective way to run many types of programs on your computer. Just remember that since the programs are not backed by a commercial company, if you have problems using the software, you will most likely not be able to obtain technical support from the developer. Of course, if you like to figure things out on your own or participate in online discussions, open source software may be just right for you.
