Hi ,
What is Noise , Fractal , Fractal Noise , Fractal Depth ,Frequency , Offset ?
In some tutorial they scroll the knob and get some output , but I dont know the meaning of it.
I have come across the term when I used mountain sop.
Can anyone help me ?

for starting you should learn about some mathematical formula such as sin , cos waves , search them in google , they are good example for knowing Frequency , Offset , Amplitude , Wavelength and etc

this is a simple example :

<<your wave>> = sin ((Frequency * value) + Offset) * Amplitude


value is different in different situations !
it can be point's number , position , angle or etc

Just check this simple example about above formula :
