    Unit 0: Introduction - Linux Fundamentals

    Lesson 1: What is Linux?

    Linux is an open-source operating system kernel that serves as the foundation for various Linux distributions, such as Ubuntu, CentOS, and Debian. Unlike proprietary operating systems like Windows or macOS, Linux is free to use, modify, and distribute.

    Key Concepts:

    1. Open Source: Linux is open source, which means its source code is freely available to the public. This fosters collaboration and innovation within the community.

    2. Kernel: The kernel is the core component of the operating system that manages system resources and interacts with hardware.

    3. Distributions: Linux distributions are variations of the Linux operating system that include the Linux kernel and various software packages.

    Example: Ubuntu is a popular Linux distribution known for its user-friendly interface and extensive software repository.

    Lesson 2: Why Use Linux?

    Linux offers several advantages over other operating systems, making it a preferred choice for developers, sysadmins, and tech enthusiasts. Some reasons to use Linux include:

    1. Customization: Linux allows users to modify the operating system according to their requirements.

    2. Security: Linux is less vulnerable to malware and cyber attacks compared to other operating systems.

    3. Stability: Linux systems are known for their stability and can run for extended periods without needing a reboot.

    4. Community Support: The Linux community is vast and offers robust support through forums, documentation, and online resources.

    Example: A web developer may prefer Linux for its development tools, command-line interface, and server capabilities.

    Lesson 3: Basic Linux Commands

    Understanding basic Linux commands is essential for navigating and managing the operating system efficiently. Here are some fundamental commands:

    1. ls: List directory contents.

    2. cd: Change directory.

    3. pwd: Print working directory.

    4. mkdir: Create a new directory.

    5. rm: Remove files or directories.

    Example: To list the contents of a directory, you can use the ls command followed by the desired directory path.

    By mastering these fundamentals, you will develop a strong foundation in Linux, empowering you to explore more advanced concepts
