Frequency Capping allows you to limit the clicks or impressions of an individual user on an ad in a single day.
For example, if you do not want to show the same ad to a single user more than 5 times, then in such a case, you can enable the Frequency Capping feature and restrict the impression to 5 impressions per day.
Similarly, you can restrict the click as well from a user in a single day.
