    Study Notes

    What is Linux?

    • Linux is a family of operating systems based on the Linux kernel.
    • The Linux kernel was created by Linus Torvalds in 1991.
    • Linus Torvalds also created Git, which is used for managing the Linux kernel.
    • Today, thousands of people and organizations contribute to the kernel's maintenance, including Microsoft, Amazon, and Google.
    • A Linux operating system also includes additional software, such as GNU utilities, a system initialization program (e.g., openrc or systemd), and application software for different purposes (e.g., desktop, web servers).
    • A Linux operating system is often called a distribution or "distro"; Ubuntu is an example.
    • The Linux kernel is the core component of the operating system, acting as the communication bridge between hardware and software.
    • The four main functions of the Linux kernel are:
      • Memory management: Tracking allocated memory
      • Process management: Managing CPU allocation for processes
      • Device drivers: Linking hardware with processes
      • System calls and security: Handling process requests.

    Server vs. Desktop Linux

    • Many Linux distributions have server and desktop editions.
    • This course focuses on server editions, mainly using a terminal interface.
    • Server and desktop editions primarily differ in installed software, with server editions lacking a desktop environment.
    • Terminal use is essential for server administration & development.
    • Practice using the terminal for common tasks (e.g., directory creation) to improve proficiency.

    Terminal vs. Shell

    • A terminal is the user interface, the window you see.
    • The shell is the software interpreting commands typed in the terminal.
    • Examples are PowerShell (Windows) and ZSH (Linux, MacOS).
    • This course will use the Bash shell. Bash is standard, default for many systems, making it ideal for learning.
