what are push notifications

Push notifications are messages that are "pushed" from a back-end server or application to a user interface, such as mobile applications or desktop applications. They can consist of a title, a message, an image, and a URL, and are designed to be viewed in real-time, often triggering immediate engagement. Push notifications can be used to convey reminders, updates, promotions, and more. They are typically opt-in alerts that display text and rich media, like images or buttons, which enable a user to take a specific action. Push notifications are an important communication channel for app publishers, providing convenience and value to app users. They can be sent to a user's mobile device and appear on the screen or in the top section of the device, even when the app is not in use. Different types of push notifications include banner notifications, alert notifications, and interactive notifications
