Answer 1

Lived up!
In fact, only 2 of the common operating systems are necessarily with a graphical user interface. These are Windows and MacOSX. They are generally the only ones where a GUI (graphical user interface) is initially required.
Windows developers, by the way, had to make special efforts to get versions where there is no such interface. This is the so-called. Windows Server Core. https://habrahabr.ru/post/138786/
All other *nix - Linux, *BSD, Solaris, etc. - initially do not have a graphical user interface. In them, it is organized as a launch of a separate program - it is called "X11 Server". Disabling this program is elementary. And - oops - you don't have a graphical user interface anymore.
Well, as you correctly noted - * nix in a number of distributions, the inclusion of X11 is selected at the installation stage. For servers, it is not included.
In contrast, distributions designed for servers do not natively have a graphical interface. If you want to enable it, you will have to install and enable X11 separately.
