What Is?
iOS is a mobile operating system developed by Apple, designed exclusively for Apple devices such as iPhone and iPad. It is known for its smooth performance, tight hardware-software integration, and strong security model.
iOS allows users to download and install apps through the App Store, which hosts millions of applications. Unlike Android, iOS is a closed-source platform, meaning only Apple controls its development and distribution. First released in 2007 alongside the original iPhone, iOS has evolved through many versions, each introducing new features, design changes, and performance improvements.
