Notification Center is a feature in iOS, iPadOS, macOS and watchOS that provides an overview of alerts from applications. [1] [2] It displays notifications until the user completes an associated action, rather than requiring instant resolution. Users may choose what applications appear in Notification Center, and how they are handled. Initially released with iOS 5 in October 2011, Notification Center was made available on Macs as part of OS X Mountain Lion in July 2012.
Notification Center was released in iOS 5 to replace the previous system for dealing with push and local notifications. Instead of interrupting the user with an alert, Notification Center instead displays a banner at the top of the screen. This allows the user to continue using their device, and disappears after a set period of time. All previous notifications are collated into the Notification Center panel, which can be displayed in iOS by dragging down from the status bar, and in macOS by clicking on the notification center icon to the very right on the menu bar at the top of the screen (or using track-pad gestures, swiping from right to left). Notifications may be selected by the user, which redirects the user to the application where the notification was initially created, and marking that alert as read. Once a notification is read, it is removed from the panel. Users may also remove notifications without reading them by deleting individual alerts, or dismissing all of an application's alerts from within the application that is generating them. When an iOS device is locked, new notifications appear on the lock screen, and users may access the application generating the alert by swiping the application's icon with their finger from left to right along the notification.
Notification Center on macOS also includes Weather and Stocks widgets, displaying information on the weather at the user's current location, and any stocks that the user has selected in the Stocks application. This feature was not available on iPad or macOS until the release of iOS 7, which added the Weather widget to the iPad's Notification Center. Users could also select the option to display Twitter and Facebook buttons, allowing them to send tweets or update their status directly from Notification Center. [3] In iOS 7, however, the option to send tweets or update Facebook statuses has been removed, and replaced with widgets.
Any application that uses the Push Notifications system provided by Apple, or local notifications, may use Notification Center. [4] Users may customise what they want to appear in Notification Center, and may opt to stop certain applications appearing in the center, or sending alerts to their screen.
macOS users may also disable alerts and banners for a day, stopping notifications appearing on the screen. This can be achieved by either opening the Notification Center panel, scrolling upward, and toggling Do Not Disturb on, by holding the Option key while clicking on the Notification Center icon in the Menu Bar, or in System Preferences. However, any notifications sent during this time are still visible in the Notification Center panel. A similar service is included in iOS 6 as part of the Do Not Disturb feature. [5]
The taskbar is a graphical user interface element that has been part of Microsoft Windows since Windows 95, displaying and facilitating switching between running programs. The taskbar and the associated Start Menu were created and named in 1993 by Daniel Oran, a program manager at Microsoft who had previously collaborated on great ape language research with the behavioral psychologist B.F. Skinner at Harvard.
Aqua is the graphical user interface, design language and visual theme of Apple's macOS and iOS operating systems. It was originally based on the theme of water, with droplet-like components and a liberal use of reflection effects and translucency. Its goal is to "incorporate color, depth, translucence, and complex textures into a visually appealing interface" in macOS applications. At its introduction, Steve Jobs noted that "... it's liquid, one of the design goals was when you saw it you wanted to lick it".
Growl is a deprecated global notification system and pop-up notification implementation for the Mac OS X and Windows operating systems. Applications can use Growl to display small notifications about events which may be important to the user. This software allows users to fully control their notifications, while allowing application developers to spend less time creating notifications and Growl developers to concentrate on the usability of notifications. Growl can be used in conjunction with Apple's Notification Center that is included in Mac OS X 10.8 and higher.
Dashboard is a discontinued feature of Apple Inc.'s macOS operating systems, used as a secondary desktop for hosting mini-applications known as widgets.

Dashboard applications supplied with macOS included a stock ticker, weather report, calculator, and notepad; while users could create or download their own.
iOS is a mobile operating system developed by Apple exclusively for its mobile devices. It was unveiled in January 2007 for the first-generation iPhone, which launched in June 2007.

A home screen, homescreen, or start screen, is the main screen on a device or computer program. Home screens are not identical because users rearrange icons as they please, and home screens often differ across mobile operating systems. Almost every smartphone has some form of home screen, which typically displays links to applications, settings, and notifications.
OS X Lion, also known as Mac OS X Lion, is the eighth major release of macOS, Apple's desktop and server operating system for Mac computers.
OS X Mountain Lion is the ninth major release of macOS, Apple Inc.'s desktop and server operating system for Macintosh computers. OS X Mountain Lion was released on July 25, 2012, for purchase and download through the Mac App Store, as part of a switch to releasing OS X versions online and every year, rather than every two years. Named to signify its status as a refinement of the previous OS X version, Lion, Apple's stated aims in developing Mountain Lion were to allow users to more easily manage and synchronise content between multiple Apple devices and to make the operating system more familiar.
iOS 6 is the sixth major release of the iOS mobile operating system developed by Apple Inc, being the successor to iOS 5. It was announced at the company's Worldwide Developers Conference on June 11, 2012, and was released on September 19, 2012. It was succeeded by iOS 7 on September 18, 2013.
A lock screen is a computer user interface element used by various operating systems. They regulate immediate access to a device by requiring the user to perform a certain action in order to receive access, such as entering a password, using a certain button combination, or performing a certain gesture using a device's touchscreen. There are various authentication methods to get past the lock screen, with the most popular and common ones being personal identification numbers (PINs), the Android pattern lock, and biometrics.
Control Center is a feature of Apple Inc.'s iOS, iPadOS, macOS, and visionOS operating systems. It was introduced as part of iOS 7, released on September 18, 2013. In iOS 7, it replaces the control pages found in previous versions. It gives iOS and iPadOS devices direct access to important settings for the device by swiping down from the top right corner on the iPhone X and newer, and on all iPad models starting with iOS 12 or iPadOS, with previous models using a swipe from the bottom of the screen. It is similar to the SBSettings tweak for iOS jailbreaking. Control Center was also added to Macs in macOS 11 Big Sur, released on November 12, 2020.
