X Window is a client server application.
*
Sorry I have many questions.
What does this mean.
I understood: A server is collecting and sending emails and files. Is
this rightß
You computer runs an X Window server that you connect to as a client.
*
Who is a client?
Who is the OS conneting?
It has just always been that way because back when X Window was
originally written most computers were not powerful enough to run the
program.
*
Window and Windows is not the same, isnt it.
There is hardware and there is an OS. The OS is conneting the hardware.
The www is a kind of hardware, isnt it?
Computers have changed, X Window hasn't. Start a terminal and issue
these commands:
$ netstat -a | grep X11
*
OK
I did it.
Something is wrong.
Nothing happened.
Man netstat did not work.
That will show you the ports your X server is running on among other things.
$ ps aux | grep -i x
This will show you your server and client processes.
*
OK
This happened:
~$ ps aux | grep -i x

I'm not sure what knowing any of this will do for you today. There was a
time when it was more important information though.

I want to learn Linux and I want to understand Linux.
Thank You.
