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. As with any operating system, the main purpose of Linux is to receive requests from various programs and convey it to the computer’s hardware. Linux does it through a graphical interface, similar to other popular operating systems that you might know including Microsoft Windows and Apple iOS.
What makes Linux different, among many other important points, is that it is completely open-source. 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.
