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.

It can sort of depend on the distro, there are a lot of Debian-based ones such as Debian (obviously), Kali, Ubuntu, and then ones based on Ubuntu like Mint and Pop!OS, those all largely work the same under the hood, ie you'd use .deb files and something like
sudo apt-get install
to install something.Then there are Arch-based ones like Arch and Manjaro, which are a bit more different, you'd use
pacman
oryay
orparu
to install things instead, and they have things like the AUR, which is a big user-maintained repository or software that has just about everything on it.Then you have the Fedora based ones and SUSE based ones, which are different again in other ways. And some more unique and weirder ones like NixOS which is having a bit of a moment, whereby you sort of configure the entire system in one single config file and rebuild it each time (as I understand it, that might be a bit off 'cause I'm still learning.)
So yeah it sort of depends. And then you have desktop environments like GNOME and KDE which aren't distros, but do affect how the whole system looks (and functions, to an extent.) And these are largely agnostic of the underlying distro, so you could have say a machine running Debian with GNOME next to a machine running NixOS with GNOME which would look very similar from the desktop but would be hugely different under the hood, and two machines running Arch, one with GNOME and one with KDE which would look totally different but be functionally the same.
I won't even start on Display Managers lol.
