Explain the Difference Between Two Similar Concepts in a Subject You Are Studying

Two concepts that seem similar enough to use interchangeably, until you use them interchangeably and something goes wrong. This explains what each means on its own, where they overlap and why, the precise point where one applies and the other does not, and one situation where getting them confused would actually matter.

Explain the difference between the two concepts described below, in the context of the subject I am studying.

For the two concepts and context:
1. What each concept means on its own, in plain language
2. Where and why they overlap (what makes them easy to confuse)
3. The clearest distinction between them: the situation where one applies and the other does not
4. One example that illustrates when getting them wrong would actually matter
