Free software, also known as open source software, can be used, modified, and redistributed while remaining open source. It is not the same as freeware and requires the source code to be available. The Free Software Foundation lists four freedoms for free software. A license and manual are usually included, and the software can be continuously improved and customized.
Free software, also known as libre software, or open source software, is a type of software that can be used and modified by the owner of the software, as well as redistributed. It can often be redistributed and sold by the person who made the changes, but still needs to remain open source. Free software is not synonymous with “freeware,” which is software that is available for free use, but which may or may not be modified. This software is also sometimes free, but sometimes requires payment to purchase; the “free” in the name refers to the fact that it can be used and modified freely.
This type of software can also be referred to as open source software. All of these terms mean the same thing and simply refer to the fact that the source code of the software is available to every person who has the software on their computer. The source code of the software should remain available both in the original version and in any modified versions; otherwise, the software can no longer be considered free. Of course, people are free to make their own personal changes to the software and not to share it with anyone. Just because the freedom to do so exists doesn’t mean it’s necessary.
Free software can be software of any kind and can be used by anyone who wants to install the software on their computer. The Free Software Foundation was first developed in 1985 by Richard Stallman and provides a list of four specific “freedoms” that help simplify the definition of free software. These are “The freedom to run the program for any purpose”, “The freedom to study how the program works and modify it to do what you want”, “The freedom to redistribute copies so you can help your fellow man”, and “the freedom to improve the program and release your improvements (and modified versions in general) to the public, so that the whole community benefits”.
In addition to the source code for publicly available free software, the software must also be accompanied by a free software license or other notice that provides additional permissions. A manual is also usually included with the software, which is also usually updated by users making changes. This type of software can be beneficial to individuals as well as larger groups or companies, as the software can be continuously improved and customized according to the needs of the users.
