What is Linux

Introduction to Linux

Linux is a free, open-source operating system (OS) based on the Unix architecture. It is widely used in servers, desktop computers, embedded systems, and mobile devices. Developed by Linus Torvalds in 1991, Linux has become one of the most popular and secure operating systems, known for its flexibility, stability, and community-driven development.

How Linux Works

Linux operates by using a kernel, which is the core of the operating system that manages hardware resources and software applications. Many different Linux distributions (or "distros") are available, including Ubuntu, Fedora, Debian, and CentOS, each offering unique features and user experiences while all using the Linux kernel as their foundation.

Advantages of Linux

• Open-source: Linux is free to use, modify, and distribute.
• Security: Known for its robust security features, making it a preferred choice for servers.
• Customization: Highly customizable, allowing users to tweak the OS to their needs.
• Performance: Efficiently manages system resources, making it suitable for both powerful and low-end machines.
