what is windows in Winfforms??

Question

Hi friends 

My doubt here it goes ---->

IN console app's

system.console.write ---> namespace.class.method -- > its well & fine 

BUT

System.windows.forms -- 

system   -   namespace

windows - ??? ???

Form      -   class right 

TY & possible redirect me to any links where i can find more syntax stuff like this  :)
