Firstly, What is an OS? A mobile operating system (OS) is software that allows smartphones, tablet PCs (personal computers) and other devices to run applications and programs. A mobile OS typically starts up when a device powers on, presenting a screen with icons or tiles that present information and provide application access. Mobile operating systems also manage cellular and wireless network connectivity, as well as phone access. There are two major players in the mobile operating system world, namely Android and Apple’s iOS. Today we will gonna study what is IOS, how it works, what is the latest ios version, it’s features, application, and much more!
What is iOS?
iOS stands for iPhone Operating System is a mobile operating system which is developed and used by Apple In exclusively for its hardware iPhone, iPod touch, and iPad. iOS runs on all models of iPhones and its primary rival is Google’s Android. iOS was first released alongside the iPhone in 2007 and began running on iPads and models of iPod Touch alike. Since then, iPod Touch has somewhat fallen by the wayside and iPad’s now run on a larger screen-friendly version of iOS, named iPadOS – even if it remains fairly similar. Over the course of thirteen (13) yrs, iOS developed very well in several areas. The main noticeable development you will see is in the app store, the App Store has become more prolific than many would have imagined.
These changes have come via another feature that is of significant appeal to iOS users – frequent updates. Apple is known for supporting its devices over many years with regular updates – from solving bugs and security issues to big releases that bring new and exciting features. iOS is the world’s second-most widely installed mobile operating system, after Android. It is the basis for three other operating systems made by Apple: iPadOS, tvOS, and watchOS. An iOS is a closed proprietary software.
Apples iOS AT A GLANCE
- Official website:- apple.com/ios/
- Apple iOS is created and developed by Apple inc. This iOS software is written in the language of C, C++, Objective-C, Swift, assembly language. iOS is based on a closed source model, with some open source components. iOS is initially released on June 29, 2007; 14 years ago. iOS update method is based on OTA method (Over-the-air programming, OTA programming) refers to various methods of distributing new software). iOS is based on hybrid kernal type (hybrid kernel is an operating system kernel architecture that attempts to combine aspects and benefits of microkernel and monolithic kernel architectures used in computer operating systems). IOS default user interface is Cocoa Touch (multi touch, GUI).
- “Unveiled in 2007 for the first-generation iPhone, iOS has since been extended to support other Apple devices such as the iPod Touch (September 2007) and the iPad (January 2010). As of March 2018, Apple’s App Store contains more than 2.1 million iOS applications, 1 million of which are native for iPads. These mobile apps have collectively been downloaded more than 130 billion times.
- Major versions of iOS are released annually. The current stable version, iOS 14, was released to the public on September 16, 2020 and it available in 30+ languages. It brought many user interface changes, including the ability to place widgets on the home screen, a compact UI for both Siri and phone calls, and the ability to change both the default web browser and email apps. No devices were dropped, as all devices supported by iOS 13 are able to run iOS 14.”
How was iOS created?
In 2005, when Steve Jobs began planning the iPhone, he had a choice to either “shrink the Mac, which would be an epic feat of engineering, or enlarge the iPod”. Jobs favored the former approach but pitted the Macintosh and iPod teams, led by Scott Forstall and Tony Fadell, respectively, against each other in an internal competition, with Forstall winning by creating the iPhone OS. The operating system was unveiled with the iPhone at the Macworld Conference & Expo on January 9, 2007, and released in June of that year, And that’s how we get our iOS.
Why was iOS created?
iOS is created for being used in Apple’s own hardware such as the iPhone and iPod Touch. This OS also plays as a basis for three other operating systems made by Apple: iPadOS, tvOS, and watchOS.
What devices use the iOS operating system?
So far so good we all know that iOS was built for Apple products. Apple has a whole ecosystem for its products that uses iOS operating system. Mainly this iOS is used in iPhones!
Difference between iOS and iOS beta
An iOS is a stable version of an operating system that was released after many experiments and testing. While the Apple iOS Beta Software Program lets users try out pre-release software.
“Beta software is intended purely for testing. Bugs may also make iOS beta software less secure. Hackers can exploit loopholes and security to install malware or steal personal data. And that is why Apple strongly recommend that no one installs beta iOS on their “main” iPhone or device”
Can iOS be hacked?
Jailbroken iPhones are at a much higher risk for being hacked since users are able to download apps from sources other than the App Store, where malicious programs are less likely to be blocked. However, researchers have demonstrated it’s possible to sneak a malicious iOS app into Apple’s official store too.
So, Yes, both Android phones and iPhones can be hacked. But as an iOS is a closed source it may create some difficulties for hackers as compared to Android OS!
The Architectural Design of iOS
The architecture of IOS is a layered architecture. At the uppermost level iOS works as an intermediary between the underlying hardware and the apps you make. Apps do not communicate to the underlying hardware directly. Apps talk with the hardware through a collection of well defined system interfaces.
Lower layers give the basic services which all application relies on and higher-level layer gives sophisticated graphics and interface related services. Apple provides most of its system interfaces in special packages called frameworks. Every layer has a set of Frameworks which the developer uses to construct the applications.
iOS has many features like interface (The iOS user interface is based upon direct manipulation, using multi-touch gestures such as swipe, tap, pinch, and reverse pinch. Interface control elements include sliders, switches, and buttons.). The Home Screen (The home screen, rendered by SpringBoard, displays application icons and a dock at the bottom where users can pin their most frequently used apps.), There is Notification Center, Folders, System font, Siri (It is an intelligent personal assistant integrated into iOS. The assistant uses voice queries and a natural language user interface to answer questions, make recommendations, and perform actions by delegating requests to a set of Internet services.) , And much more.
What is the latest ios version?
iOS 14 is the latest iOS version so far, It brought many user interface changes, including the ability to place widgets on the home screen. A compact UI for both Siri and phone calls came into existence, and the ability to change both the default web browser and email apps.
iOS 14 features
iOS 14 is compatible with all the devices which are able to run on iOS 13 which makes this new iOS 14 more user-friendly. Here are some of new additions of the latest iOS 14.
Home screen redesign with widgets
iOS 14 introduces a new design for the Home Screen that allows for far more customization with the incorporation of widgets, options to hide entire pages of apps, and the new App Library that shows you everything you have installed at a glance.
Customized Home Screen Icons
Along with widgets for Home Screen customization, iPhone users have discovered that their Home Screens can be further customized with unique icons using the Shortcuts app.
New App Library
App Library is a great new feature that shows all of the apps you have installed in an organized, simple-to-navigate view that’s similar to the app list view on the Apple Watch.
Picture in picture
The Picture in Picture feature on the iPad OS is expanded to the iPhone in iOS 14, and you can now watch videos or use FaceTime while doing something else.
No full screen calls
Incoming phone calls no longer take up the entire screen in iOS 14, and instead show up as a small banner at the top of the display. Swipe up on the banner to dismiss it, or swipe down to see more phone options and answer the call. You can also tap right on the banner’s accept and reject buttons to accept or decline a call.
Third-Party Default Apps
For the first time since iOS was introduced, third-party mail and browser apps can be set as the default in place of Mail and Safari. That means Chrome users and those who prefer email apps like Spark, Edison, and others, can use their favorite apps more easily.
If you have an electric vehicle, you can get directions that include charging stops along the route and ETAs that account for charging time. When an electric vehicle is added to an iPhone, Maps can keep track of the current charge and charger type to provide the best route options for your particular vehicle. This is a great improvement in iOS 14.
App Clips, new to iOS 14, let you use a part of an app at the moment that you need it without having to download the full app. For example, if you want to make a quick reservation at a restaurant through an app like Yelp, you might be able to use the Yelp App Clip to get it done without the hassle of installing the Yelp app.
Apple improves privacy protections for its customers with every iteration of iOS, and iOS 14 is no exception, making it clearer what info apps collect, requiring more user permission, and providing ways to use location features without providing specific location data.
Applications of iOS
iOS devices come with preinstalled apps developed by Apple including Mail, Maps, TV, Music, FaceTime, Wallet, Health, and many more. Applications (“apps”) are the most general form of application software that can be installed on iOS. They are downloaded from the official catalog of the App Store digital store, where apps are subjected to security checks before being made available to users.
Applications for iOS are mostly built using components of UIKit, a programming framework. It allows applications to have a consistent look and feel with the OS, nevertheless offering customization.
What is UIKit (cocoa touch):- Cocoa Touch is the application development environment for building software programs to run on iOS for the iPhone and iPod Touch, iPadOS for the iPad, watchOS for the Apple Watch, and tvOS for the fourth-generation Apple TV, from Apple Inc.
UIKit elements are very adaptable, this allows developers to design a single app that looks the same on any iOS device. In addition to defining the iOS interface, UIKit defines the functionality of the application.
As Apple did not want any third party apps to be developed for iOS so at first they do not allow or intend to release an SDK for developers. However, this technology never entered into common use, which led Apple to change its opinion, so in October 2007 the SDK for developers was announced, finally released on March 6, 2008.
What is SDK? SDK is a set of tools for third-party developers to use in producing applications using a particular framework or platform, developers are required to subscribe to the Apple Developer Program. Over the year, the Apple Store apps surpassed multiple numbers in applications of 50,000, 100,000, 250,000, 500,000, 1 million, and 2 million apps.
