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.
Evolution of Apple iOS versions
Apple's iOS, the Operating System that empowers iPhones, iPads, and iPod Touch devices, has undergone a remarkable evolution since its inception. Launched in 2007 alongside the first iPhone, iOS 1.0 introduced a revolutionary touch-centric interface and essential features like the App Store. Subsequent versions refined the user experience and expanded functionality.
iOS 4, released in 2010, marked a significant shift with the introduction of multitasking, allowing users to run multiple apps simultaneously. iOS 7, in 2013, brought a visually striking redesign, flat icons, and enhanced multitasking capabilities. iOS 9, released in 2015, focused on performance improvements and introduced the proactive Siri assistant.
iOS 11, unveiled in 2017, introduced the Files app, augmented reality capabilities, and a redesigned App Store. Further, iOS 14, released in 2020, featured customisable widgets, App Library, and App Clips for quick app access. The latest version, iOS 15, launched in 2021, prioritises communication with FaceTime enhancements, introduces Focus modes for personalised notifications, and enhances privacy features.
Key features of the iOS platform
Now that you know What is iOS, let’s learn about its amazing features. This Operating System is known for its user-friendly, elegant, and consistent design, which makes it easy to use and navigate. Some of the key features of the iOS platform are:
a) Multitasking: Introduced with iPhone 4 and 3GS, iOS enables seamless app switching through multitasking features and multi-finger gestures on iPads.
b) Social media integration: iOS facilitates easy content sharing and incorporates activity streams, seamlessly integrating social network interactions into apps.
c) iCloud: Apple's internet-based data storage service, iCloud, operates across all Apple devices and certain Windows platforms, ensuring secure data storage with encryption and offering backup options.
d) In-App purchases: Available on all Apple platforms, in-app purchases allow users to acquire additional digital items, subscriptions, and premium content directly within apps, with the App Store serving as a platform for promotion and sales.
e) Game centre: Apple's social gaming network, Game Center, enhances gaming experiences by providing features such as leaderboards, achievements, multiplayer capabilities, and a dashboard.
f) Notification centre: iOS consolidates app alerts in the Notification Center, allowing users to manage notifications at their convenience with customisable settings.
g) Accelerometer: Every iOS device incorporates a three-axis accelerometer, detecting changes in velocity along each axis and enhancing device functionality.
h) Gyroscope: iOS devices feature a three-axis gyroscope, measuring rotational data in each of the three axes, contributing to advanced functionality.
i) Assisted GPS - AGPS: The iPhone utilises an inbuilt AGPS chip for location detection. This provides a quick and accurate approximation of the user's location based on satellite information.
j) Accessibility: Apple products and services are designed with one-tap accessibility features. Thus, Apple ensures ease of use and alignment with users' preferences.

Working of iOS
iOS is a layered system, meaning that it consists of several layers of software components that work together to provide the functionality and performance of the system. The layers of iOS are as follows:
a) Core OS: It is the lowest layer of iOS and provides the basic services and frameworks for the system, such as the kernel, drivers, security, encryption, networking, and power management.
b) Core services: This layer is above the Core OS and provides the essential services and frameworks for the system, such as the file system, databases, iCloud, Core Foundation, Core Location, Core Motion, and more.
c) Media: The Media layer provides the services and frameworks for the audio, video, graphics, and animation of the system, such as the Audio Toolbox, AV Foundation, Core Audio, Core Graphics, Core Image, Core Text, Core Video, and more.
d) Cocoa touch: It is the highest layer of iOS and provides the services and frameworks for the user interface and interaction of the system, such as the UIKit, Foundation, Event Kit, Game Kit, Map Kit, Message UI, and more.

Security and privacy features in Apple's iOS
iOS is designed to be secure and private and to protect the user’s data and identity from unauthorised access and misuse. Some of the security and privacy features in iOS include the following:
a) Encryption: iOS encrypts the user’s data, such as photos, messages, contacts, and more, using a unique device key and a user passcode. This means that only the user can access their data, and no one else, not even Apple, can decrypt it.
b) Face ID and Touch ID: Face ID and Touch ID are secure and convenient ways to access the device and can also be used to authorise payments, sign in to apps, and more.
c) App Store: iOS ensures that the apps that are available on the App Store are safe and trustworthy. The applications undergo a rigorous review process by Apple before they are approved and published.
d) Privacy settings: iOS allows users to control and manage their privacy settings, such as location services, camera, microphone, contacts, and more, and to choose which apps can access them.
e) Sign in with Apple: iOS allows users to sign in to apps and websites using their Apple ID, without creating a new account or sharing their email address.
f) Safari: iOS allows users to browse the web safely and privately using the Safari browser, which has various features and settings, such as Intelligent Tracking Prevention, which blocks third-party trackers and cookies.
