What is the meaning of iOS?

iOS is a software platform that runs on Apple’s digital devices, such as the iPhone, iPad, iPod touch, and Apple TV. iOS stands for iPhone Operating System, although it is not limited to the iPhone. iOS is based on the Mac OS X Operating System, which is derived from the Unix operating system.

iOS is a closed-source system, meaning that Apple does not publicly release the source code of iOS, and only Apple can modify it. However, iOS supports third-party applications, which are software programs that can be downloaded from the App Store and installed on iOS devices. This Operating System also supports various frameworks and libraries, which are collections of code that provide common functions and features for developers to use in their applications.
