From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Hi all - I am learning about Linux and want to see if my understanding is correct on this - the list of major parts of any distro:

the Linux Kernel
GRUB or another bootloader
one or more file systems (gotta work with files somehow, right?)
one or more Shells (the terminal - bash, zsh, etc...)
a Desktop Environment (the GUI, if included, like KDE or Gnome - does this include X11 or Wayland or are those separate from the DE?)
a bunch of Default applications and daemons (is this where systemd fits int? I know about the GNU tools, SAMBA, CUPS, etc...)
a Package Manager (apt, pacman, etc...)

Am I forgetting anything at this 50,000 foot level? I know there are lots of other things we can add, but what are the most important things that ALL Linux distributions include?

Thanks!

You pretty much got it, except for the fifth point.

A desktop environment ("DE") is separate from the compositor (X11 or Wayland), but can't exist without it.

At the end of the day, a DE is really just a "window manager" with a bunch of bundled applications, like taskbars/panels, a file manager, an app menu, etc. It's as minimal or as feature rich as you want it to be.

The window manager dictates what to draw on the screen and where, but the compositor is what actually does the work. One is kind of useless without the other.

Hopefully that makes sense, I'm not a rocket surgeon.
