can anyone send information including mathematics too regarding Discrete time fourier transform and Discrete Fourier Transform.?? along with difference b/w them.
 

The two might very well be two names for the same thing.

Are you sure you don't want the difference between the "finite Fourier transform" and the "discrete Fourier transform"?

Sorry (got it now) - your term's correct.
I know I've seen a table of properties of four Fourier transform variants - two based on integrals, and two based on summations. (looking)

Added after 5 minutes:

Look here
https://encyclopedia.thefreedictionary.com/Fourier transform
There's a table to do with "continuous", "discrete", "periodic", and "aperiodic" - that's the main difference:
The character of the data and the spectrum.
