Linux is an open-source operating system that was first developed in 1991 by Linus Torvalds. It is based on the Unix operating system and is designed to be stable, secure, and scalable. Linux is used in a wide variety of applications, including servers, supercomputers, mobile devices, and embedded systems.

One of the key features of Linux is its open-source nature. This means that the source code for Linux is freely available to anyone who wants to use or modify it. This has led to a large community of developers who contribute to the development of Linux and create their own versions of the operating system, known as distributions.

Linux is also known for its stability and security. It is designed to be resilient to crashes and system failures, and it includes built-in security features such as firewalls, encryption, and access controls. This makes Linux an ideal choice for servers and other mission-critical applications.

Linux is highly customizable and can be configured to suit a wide variety of applications and use cases. It includes a powerful command-line
