Linux (pronounced Listeni/ˈlɪnəks/ LIN-əks or, less frequently, /ˈlnəks/ LYN-əks) is a Unix-like computer operating system assembled under the model of free and open-source software development and distribution. The defining component of Linux is the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. The Free Software Foundation uses the name GNU/Linux to describe the operating system, which has led to some controversy.
