KDE=KDE Display manager

Sir,

Thanks for the info. I have actually visited these places and did not find the answer that's why I went back here.
GNU - GNU Not Unix is the normal thing that I read, while K Desktop environment is for KDE.
I'm just curious at the real meaning. I wish somebody here really knows it.

The GNU is very simple.

Lisp is a programming language in which recursive logic is very common. Richard Stallman was/is a lisp programmer. The naming is a lisp programmer's play on words, using recursive logic. The G doesn't actually stand for anything and is self referential (and thus recursive). It's a simple as that.

The logic of KDE is a little different, KDE was simply chosen because in many languages K and C are pronounced the same way. This time it's a play on sound. There is nothing more to it than that.
