Introduction to Linux






Linux is a free and open-source operating system based on the Unix operating system. It was first released in 1991 by Linus Torvalds as a personal project, and has since grown into one of the most widely used operating systems in the world.

One of the key features of Linux is its open-source nature, which means that the source code is freely available and can be modified and distributed by anyone. This has led to a vibrant community of developers and users who collaborate to improve and maintain the software.

Linux is used on a wide range of devices, from servers and supercomputers to smartphones and embedded devices. It is known for its stability, security, and flexibility, and is widely used in enterprise computing environments.

There are many different distributions, or "distros," of Linux, each with its own features and characteristics. Some of the most popular distros include Ubuntu, Debian, Fedora, and CentOS.

Linux also has a rich ecosystem of open-source software, including web servers, databases, development tools, and more. The command line interface, or terminal, is a key aspect of using Linux and allows users to interact with the system using text commands.

Overall, Linux is a powerful and versatile operating system that has played a key role in the growth of open-source software and the Internet.
