Is Gaussian Noise and White Gaussian Noise (WGN) the same thing? Or got any difference?

Thank you..

they are different.
'White' processes refer to the proceses where the power associated with each frequency component is same ie you see the power spectrum as constant.
when the power associated with gaussian channel is a white process you address the gausian channel as white gaussian channel
