fingerprinting is dipping your fingers in ink leaving an impression of your unique fingerprints, and DNA fingerprinting involves matching DNA at a genetic level

Fingerprinting is the act of taking a physical copy of one's fingerprints. DNA fingerprinting, on the other hand, is much more complicated.

The chemical structure of everyone's DNA is the same. The only difference between people (or any animal) is the order of the base pairs. There are so many millions of base pairs in each person's DNA that every person has a different sequence.

Using these sequences, every person could be identified solely by the sequence of their base pairs. However, because there are so many millions of base pairs, the task would be very time-consuming. Instead, scientists are able to use a shorter method, because of repeating patterns in DNA.

These patterns do not, however, give an individual "fingerprint," but they are able to determine whether two DNA samples are from the same person, related people, or non-related people. Scientists use a small number of sequences of DNA that are known to vary among individuals a great deal, and analyze those to get a certain probability of a match.

you're not stupid only ignorant.i don't mean this in a bad way,
what i mean is that it's alright to ask if you don't know.
it's better than not asking and remaining ignorant.(now that's really stupid!!)
finger printing is taking the prints from the raised ridges on your finger tips as it makes contact with any surface.(the reason being that it is thought to be unique to each person.)to identifying persons at a place( i mean if your finger prints are there then you must have been there to place it.)
DNA fingerprinting is extracting DNA from organic samples(bodily fluids,hair nail and so on). breaking it down and anlysing
it. the DNA structure is unique to each individual just like a finger print.
incidentally the DNA is the molecue that defines the physical characteristic of every living thing(plants included)
God bless,
