Today, the three main players are Windows, macOS, and GNU/Linux.
Windows is a closed operating system. It requires the purchase of a software license. It is one of the most popular operating systems with a huge selection of available programs and games. It is still the standard operating system for casual and competitive gaming. However,
macOS ia a Unix operating system, developed by Apple, specifically for their Macintosh line of computing machine systems. Every Mac is preinstalled with the macOS and updated every year or so. It is well known for having a user friendly and clean interface, better optimization of hardware and software, high prices, more secure than Windows (less malware), and limited gaming options.
GNU/Linux is a free operating system originally developed by Linus Torvalds in 1993. It’s available for everyone to download, use, modify, and distribute it at no cost. Linux comes in many flavors, commonly known as distributions, such as Debian, Arch, and Fedora. More importantly, you should use open source operating systems and applications to avoid vendor lock-in.
Free software is one answer to a world built-in proprietary (expensive) code. What does free software mean? Free software is like cooking for yourself. It is more work, but it is cheaper, tastier, you know what you are doing (you have the recipe), and it is better for you. Free software means you are free to download, use, copy, modify, and redistribute it.
Manjaro is a user-friendly, desktop-orientated Linux distribution based on Arch. EndeavourOS is a terminal-centric distro with a vibrant and friendly community at its core based on Arch.
