What is IOS?

iPhone Operating System, also known as iOS is a mobile operating system created and developed by Apple Inc. It is exclusive to Apple hardware, such as the iPhone, iPad, and iPod touch.

iOS is based on the Darwin operating system and has four abstraction layers: the Core OS layer, the Core Services layer, the Media layer, and the Cocoa Touch layer.

The Core OS layer contains the basic operating system functions of iOS, such as memory management and networking. The Core Services layer contains higher-level functions, such as file system access and sqlite databases. The Media layer contains multimedia functions, such as audio and video playback. The Cocoa Touch layer contains the graphical user interface functions of iOS.

IOS was first released in 2007 with the original iPhone. The latest version of iOS is iOS 13, which was released on September 19, 2019.
