What is Linux?

Linux is a free and open-source operating system known for its high security and multi-user capabilities. It serves as an interface between the hardware and the user, enabling efficient computing.

What is an Operating System (OS)?

An OS is system software that manages hardware components and allows users to run applications like web browsers, office tools, games, and more.

Key Components of Linux

  1. Kernel: The core of Linux, managing CPU, memory, and peripherals.
  2. Daemons: Background services like printing, sound, and scheduling.
  3. Shell: A command-line interface (CLI) or graphical user interface (GUI) for interacting with the system.
  4. Commands: Instructions given to the OS for specific tasks.
  5. Terminal: A text-based interface for running shell commands.

Popular Linux Distributions (Distros)

  • RedHat
  • Ubuntu
  • Debian
  • CentOS
  • Fedora
  • OpenSUSE

  1. Freedom to run the program for any purpose.
  2. Freedom to study and modify the program.
  3. Freedom to distribute copies.
  4. Freedom to share modified versions.
