I think the problem is that certain subfields use different terminology to mean similar or identical concepts. For example, while I'm in software, I tend to hear the terms sensitivity and specificity. They are historically medical terms. They aren't identical to recall/precision, but I think you can derive one set from the other.

The fundamental thing to know is the confusion matrix. There are about a dozen terms for various descriptors of the matrix, but they all can be calculated if you know the confusion matrix. The Wikipedia page has a great table to describe them all:

You can see from that that sensitivity and recall are the same thing, but specificity and precision are not.
