In the case of the present perfect tense, it is used to describe actions that were completed in the past but have a connection to the present moment. It indicates that the action has relevance to the current situation or has an ongoing impact. For example, “I have finished my homework” suggests that the completion of the homework has a direct relationship to the present moment, possibly implying that the person is now free to do something else.

Similarly, the past perfect tense is used to show that an action was completed before another action or point in the past. For instance, “I had finished my presentation before the meeting started” conveys that the completion of the presentation preceded the start of the meeting.
