Saya mau tau Pemberitahuan dari Windows Aero. Jelaskan dalam bahasa melayu

Notifications allow an application or operating system component with an icon in the system tray to create a pop-up window with some information about an event or problem. These windows, first introduced in Windows 2000 and known colloquially as "balloons", are similar in appearance to the speech balloons that are commonly seen in comics. Balloons were often criticized in prior versions of Windows due to their intrusiveness, especially with regard to how they interacted with full-screen applications such as games. Notifications in Aero aim to be less intrusive by gradually fading in and out, and not appearing at all if a full-screen application or screensaver is being displayed – in these cases, notifications are queued until an appropriate time. Larger icons and multiple font sizes and colors are also introduced with Aero's notification windows.
