What is Linux?

Linux is a group of open source operating systems created in 1991 by Linus Torvalds. It's based on the Linux kernel, an essential building block that enables communication between computer hardware and applications.

Because Linux is open source, many versions, called distributions, have been created for various purposes, including personal computers, servers, and corporate networks.

Why learn Linux?

  • Powers major technologies, including more than 2 billion Android devices, since Android is built on the Linux kernel.
  • Highly customizable, allowing users to tailor the system to their specific needs.
  • Free and open source, meaning users can install, use, and distribute it without licensing fees.
  • Offers a wide range of distributions, including specialized systems designed for security, development, and enterprise use.
  • Minimizes downtime by allowing users to install updates and upgrades without rebooting the entire system.
