This document provides information about the two major mobile operating systems: iOS and Android. iOS controls devices like the iPhone and iPad and is developed by Apple using programming languages like C, C++, and Objective-C. Android is an open-source, Linux-based OS that allows for more customization than iOS but may lack some of the security of Apple's closed system. Both operating systems continue to evolve and improve with regular updates that add new features.
