Linux, an open-source operating system, has gained immense popularity due to its flexibility, stability, and security. If you’re new to Linux, this guide will provide you with a solid foundation.

What is Linux?

Linux is a Unix-like operating system that was originally developed by Linus Torvalds. Unlike Windows or macOS, Linux is not owned by a single company. This open-source nature allows anyone to contribute to its development.

Key Features of Linux:

• Open-source: Linux is free to use, modify, and distribute.
• Multi-user: Multiple users can access a Linux system simultaneously.
• Multitasking: Linux can run multiple programs at the same time.

A Linux distribution is a complete operating system based on the Linux kernel. Popular distributions include Ubuntu, Fedora, Debian, and CentOS.
