Linux

 Linux is a powerful, open-source operating system (OS) and it is popular in various computing environments, from personal desktops to servers and embedded systems. Created by Linus Torvalds in 1991, Linux was initially a small, kernel-based system, but it quickly grew into a full-featured OS thanks to contributions from developers worldwide. As a Unix-like OS, Linux inherits many of the design principles of Unix, such as modularity, stability, and multitasking capabilities.

Linux Features 

1. Open Source: Linux is released under the GNU General Public License (GPL), which allows users to freely access, modify, and distribute the source code. This openness has fostered a large community that collaborates to improve Linux.

2. Security: Linux is highly secure due to its strict user permissions, process isolation, and regular updates. Its open-source nature also allows for continuous security auditing.

3. Customizability: Users can customize Linux extensively, from the kernel to the desktop environment. This flexibility makes it ideal for a variety of uses, including custom servers, desktop environments, and embedded devices.

4. Multitasking and Stability: Linux excels in handling multiple tasks efficiently without sacrificing performance. It is known for its reliability, making it popular for servers and other critical applications.

5. Portability and Cross-Platform Compatibility: Linux can run on a variety of hardware, from high-performance servers to embedded devices and even mobile phones. Android, for example, is based on a modified version of the Linux kernel.
