I want to thank THX for posting the laundry list of distros, at same time, I wish to explain to anyone new to Linux not to be intimidated by the size of this list. I have often made the analogy of Windows and Linux being tailor shops. Microsoft offers you a one-size fits-all blue suit, while Linux community has custom fits.
@Akkar_Kardashev Debian is one of the first distros to use the Linux kernel. I always thought the origin of the name was sweet, as it is named for the husband and wife team who created it. Ian Murdock and Deb Murdock, gave birth to it in 1993. They also named the distros after characters from Toy Story.
For everyone needs or wants to understand the jargon here.
Kernel - The core operating system that runs the CPU, memory, and devices through to the applications. That is why we refer to the scope of this as Linux OS.
Distro or Distribution - The product which includes all the programs needed to operate the OS. While the size can vary, the minimal would include a package manager, tools, libraries, and either a terminal, or graphic interface, to get the system installed.
Desktop Environment or DE - This is how your system appears on screen, a package of apps to interact with your PC. Most DEs typically consists of icons, windows, toolbars, folders, wallpapers, and desktop utilities. For example; OpenBox DE is nothing more than a black screen, right click and one gets a menu. Meanwhile KDE Plasma has numerous widgets the user can use to access CPU temps, monitor hardware, or just have a goofy set of âEyesâ follow the mouse cursor around the screen. Gnome, Xfce, Mate, LXDE, Cinnamon, etc. are the DEs and you can host as many as you are willing to install on your system.
WINE - Acronym for Wine Is Not an Emulator. Most of us are aware of the redundancy loop within the acronym. Some people assume it means WINdows Emulator, which is not an accurate description at all. However no emulation or virtualization is used. WINE is a compatibility layer available for both Linux and MAC OS. Valve ( Steam ) works with Codeweavers to produce Photon a Wine-based compatibility layer for games. Meanwhile Codeweavers sells their customer supported version of Wine titled CrossOver.
Game Managers - Steam, Lutris, and PlayOnLinux are front-ends and game managers for the WINE application or one of its derivatives. Most will host scripts and various WINE builds for specific titles.
There are more layers to Linux than an onion, but in the end, it your OS, you own it.
