Linux is a free and open-source operating system that is widely used in computer systems, servers, mobile devices, and other embedded systems. It was created by Linus Torvalds in 1991 as an alternative to traditional proprietary operating systems.
Unlike proprietary operating systems like Windows and macOS, Linux is distributed under various open-source licenses, which means that the source code is freely available and can be modified and distributed by anyone. Linux is also known for its stability, security, and flexibility, and has become a popular choice for both personal and enterprise use.
Linux comes in various distributions, or "distros," each with its own unique features and package management systems. Some of the most popular distributions include Ubuntu, Debian, Fedora, and Red Hat Enterprise Linux. Linux also supports a wide range of programming languages, tools, and applications, including those used for web development, machine learning, and scientific computing.
One of the key benefits of Linux is its ability to run on a wide range of hardware, including older and less powerful machines, making it an excellent choice for systems with limited resources. Linux also has a large and active community of developers, users, and contributors who continually improve and enhance the operating system.
