Why can't there be file/folder named con?

I am unable to make a file/folder with name con. I receive a message stating
that 'con' is a reserved device name. Why is it so?

Con is the name of the file that for writing is the screen and for reading is the keyboard.

Type

copy con file.txt

<type some crap>

Ctrl + Z

You just copied the keyboard to a file

Con is the name of the keyboard (if reading) or monitor (if writing). This con file exists in every folder.
