Linux is an operating system (OS). It is free software, meaning it is available to the public, and it operates on a large variety of computer hardware. Linux is considered an open-source OS meaning you can edit, change it, and re-distribute it as you wish.

Linux was originally created by Linus Torvalds in 1991. It is mainly used on servers, but the desktop version of Linux has become more popular for certain tasks.

Linux offers increased stability over other operating systems because it does not require rebooting after every update or upgrade. It also has a much lower cost than many other operating systems because there are no license fees associated with it.

Linux has many different distributions (or “distros”), which are available for free download. You can also purchase CDs or DVDs with Linux preinstalled on them. Depending on what you want to do with Linux, you will need to choose one of these distributions, as each distro has its own features and interfaces.

There are 2 main types of Linux, either desktop or headless servers.

The main difference between Desktop and Server is the desktop environment. While a Desktop includes a graphical user interface, the Server does not. This is because most servers run headless without a keyboard, mouse, or monitor setup. These servers are usually remotely managed using SSH.
