iOS

iOS (formerly iPhone OS) is a mobile operating system developed and marketed exclusively by Apple for its iPhones, iPads, and iPod Touches. It’s known for its user-friendly interface, robust security features, and seamless integration with other Apple products and services. Here’s a breakdown of its key characteristics:

• Closed-source: Unlike Android, iOS is a closed-source operating system, meaning its core code is not publicly available for modification by third parties. This allows Apple to maintain tight control over the user experience and prioritize security.
• Touchscreen interface: Designed for intuitive interaction with touchscreen displays, utilizing gestures like tapping, swiping, and pinching.
• App Store: Apps are primarily distributed through the App Store, a curated marketplace vetted by Apple, ensuring a degree of quality and security.
• Cocoa Touch framework: Provides a framework and APIs for developers to build applications using the Swift programming language.
• Security: Prioritizes security through features like sandboxing (isolating apps from each other) and regular software updates to address vulnerabilities.
• Integration with Apple ecosystem: Integrates seamlessly with other Apple devices and services like iCloud, FaceTime, and iMessage, creating a cohesive user experience.
