What does DND mean?

Do Not Disturb (DND) is a feature of Apple’s iOS operating system. When DND is turned on, it sends incoming calls to voicemail and does not alert you about calls, text messages, and notifications from making your phone ring or light up. So that you won't get disturbed by the phone when you go to bed, or during meetings, and movies.

Note:
You can also schedule DND and allow calls from certain people.
