Unlike Windows and MacOS, the Linux ecosystem is a lot more modular. For example, graphical user interfaces. There are a few types, ranging from ruthlessly simple tiling window managers to more complex desktop environments that more closely resemble the Windows or MacOS experience.
Linux users may take their pick between about a dozen desktop environments (DEs), including Gnome, Cinnamon, Mate, xfce and LXQT.
KDE (once standing for Kool Desktop Environment, now merely KDE) is a community/organization that produces open source software. They made Krita, a raster art program, KDENLIVE, a video editor, and many other such utilities. They also make the Plasma desktop environment, which is often referred to simply as "KDE" by distro maintainers. For example, you might download Fedora GNOME or Fedora KDE.
KDE Neon is an operating system maintained by KDE which features the Plasma desktop.
The kind of thing you interact outside of installed app/programs. Like the panels, window decorations (titles, close buttom, maximalize button), the way windows float and behave, system settings, etc.
Unix systems (like Linux) are very modular and you can install different desktop environments if you want. And even within those desktops are modules, like you can install different "start menu" or file manager on KDE Plasma.
raises pendantic finger Ah-hem, sorry, but KDE Plasma isn't an OS. It's a desktop environment. For an OS bundled/built-around Plasma then Kubuntu or KDE Neon are both Linux distributions that would better fit that description.
KDE's plasma centered Linux Operating system. So to not be overly pedantic, I stuck with what this lemmy post was about. I didn't say the plasma desktop environment was an OS.
I said "a linux operating system made by the KDE team" in which the KDE team referenced their OS as Plasma in the Mastodon post, or "toot," shown in this lemmy post.
Things are more interesting in the Linux world. Plasma is just a user interface, a desktop environment. The actual operating system is Linux. And we have so many choices for how we want our desktop environment on Linux, but Plasma is the most advanced one.
I said its a linux operating system, and the whole installation from Desktop environment to the compiled kernel and preinstalled executables was carefully made by the KDE team. They literally said Operating system on their mastodon post, "toot," this lemmy post shows. So its correct what I said
Oh sure, defending people who aren't even willing to read the text of the post while also attacking the one who complains about that circumstance is better, right?
Well, although usually it's a good idea to read the original post first, in this instance the original post is at best misleading because it refers to Plasma as an "operating system" rather than a desktop environment.
(Or for those who want to use even more precise terminology: its full name is either "Plasma Desktop" or "KDE Plasma Desktop", because KDE also has some non-desktop environments such as Plasma Mobile and Plasma Bigscreen... none of which are as popular as Plasma Desktop, though, so usually Plasma Desktop is colloquially called just "Plasma".)
I never said anything regarding the truth of the original posts claim; it's just irritating when people start asking questions without even reading what was initially written.
