Open source
A software for which the original source code is made freely available for use, modification, and redistribution. It grants users of an application permission to fix broken links, enhance the design, or improve the original code. Open source software may be developed in a collaborative public manner and is a prominent example of open collaboration that can broaden design perspectives far more than a single company or design work group. Open source practices can also lead to considerable savings, with many open source offerings provided to consumers for free, relying instead on a shareware or donation model.
