Linux is one of the largest open-source projects in the world! It is a versatile operating system that can be used anywhere from cheap mobile phones to large-scale supercomputers.

Anyone is allowed to run, study, and modify the source code, or even sell copies of their updated code under the same license. It has a massive developer and support community that contributes actively to its updates and development.What makes Linux different, among many other important points, is that it is completely open-source.
