Linux is a widely used open-source operating system that was created by Linus Torvalds in 1991. It is a free and powerful operating system that is used in a wide range of devices, including desktop computers, servers, mobile devices, and embedded systems. Linux is known for its stability, security, flexibility, and the ability to customize it to suit individual needs. The creation of Linux was a response to the limitations of proprietary operating systems that were expensive and had closed-source codes. Torvalds, a computer science student at the University of Helsinki, started developing Linux as a personal project, but it soon gained popularity among other computer enthusiasts who contributed to its development. One of the key features of Linux is that it is open-source, which means that the source code is freely available for anyone to access, use, modify, and distribute. This has led to a large community of developers who have contributed to the growth and improvement of Linux over the years
