Pop-up notification

The terms Pop-up notifications, toastings, Poptart, passive pop-ups, desktop notifications, notification bubbles, rustings, balloon notifications or simply notifications all refer to a graphical control element that communicates certain events to the user without forcing them to react to this notification immediately, unlike conventional pop-up windows. Desktop notifications usually disappear automatically after a short amount of time. Often their content is then stored in some widget that allows the users to access past notifications at a more convenient time.

In Windows 2000, Microsoft introduced balloon help-like passive pop-up notifications, tied to the notification area of the task bar. Notifications get queued when user is away or screensaver is running, and get shown when the user resumes activity. They remain on screen for nine seconds while fading out if the user appears to ignore them. Microsoft also adopted similar notifications for its other software such as Windows Phone using the Microsoft Push Notification Service,Internet Explorer 7 and later, Microsoft Outlook, Microsoft Security Essentials, as well as Windows 8 and Windows 10 using the Windows Notification Service.

Desktop notifications are a proposed standard for freedesktop.org but all the major desktop environments running on the X Window System already support this standard, making them typically available on Linux and other Unix-like systems. Google adopted the concepts of notification drawer and toast popup messages for user notifications as basic components of its Android operating system.
