Gerund vs. infinitive

Good evening teachers.
Hope you all are fine.

Please tell me the difference between “gerund and infinitive”. Does the use of these two really make any difference in the meaning of a sentence if we use it alternativly?

please define it fully.I would really appreciate your input. Thanks a million in
