Open Source
Generally, “open source” refers to a computer program in which the source code is available to the general public for use and/or modification from its original design. Open-source code is typically a collaborative effort where programmers improve upon the source code and share the changes within the community so that other members can help improve it further. Open source software is free. Some organizations have capitalized off of providing support and modification services for open source software such as RedHat, Inc.
