Real-time notifications are alerts that are sent instantly to users as events occur. These notifications can come from various sources, such as mobile apps, websites, or messaging platforms, and are designed to keep users informed about important updates, messages, or changes in status. For example, a social media app might send a notification when someone likes your post, while a weather app might alert you to severe weather conditions. These notifications are typically delivered through push notifications or in-app alerts, ensuring that users receive timely information without needing to refresh or check for updates manually. Real-time notifications enhance user engagement and improve communication by providing immediate feedback and updates related to applications, services, or events.
