Whether you\u2019re an Apple user or not, pretty sure you\u2019re wondering what iOS stands for. What iOS actually does and how does it run your iPhone and iPad? You\u2019ve come to the right place as we are going to discuss iOS and the evolution of Apple products from their desktops to laptops, tablets and mobile phones.\r\nBefore going over the details on what does iOS stand for, let\u2019s discuss the evolution of Apple products and why Apple created iOS.\r\n\r\n\r\n\r\n\r\n \r\nEvolution Of Apple Products\r\nThe first Apple computer was launched in April 1976 by Steve Jobs and Steve Wozniak. Apple have been developing different devices since then, from computers to laptops, tablets and printers. In 1984, Macintosh was introduced in the market.\r\nBut not until 1998 when they first announced the iconic \u201ci\u201d branding with the iMac. According to Jobs, the primary meaning of the brand is \u201c..comes from the marriage of the excitement of the internet, with the simplicity of Macintosh. \r\nApart from the reference to Internet and iMac\u2019s focus on giving the consumers a good online experience, Jobs explained that the \u201ci\u201d in the branding has so much more meaning to it. The iMac\u2019s main\u00a0focuses were the consumers and the education market which supports the other themes of \u201ci\u201d which is individual, instruct, inform and inspire.\r\nOne year later, iBook was presented at Macworld as Apple\u2019s consumer notebook or as an \u201ciMac to go\u201d. In a small event in 2001, Jobs unveiled the iPod. Because of the massive popularity of the iPod, the \u201ci\u201d branding has become a household name. And in 2007, iPhone was revealed to the public featuring it as a breakthrough internet communications device.\r\nThe iPod touch was released after the iPhone, in the fall of 2007. Both of these devices were running on iPhone OS fro 3 years until 2010, when iOS was introduced. Since then, Apple has been releasing updates for its mobile devices annually.\r\n\r\n\r\n\r\n\r\n \r\nWhat Does iOS Stand For?\r\nThe term iOS (formerly known as iPhone OS) means iPhone Operating System. IOS is an operating system developed by Apple exclusively for the company\u2019s mobile devices, including iPhone and iPod Touch and iPad also runs through iOS prior to the introduction of iPadOS this 2019. This is also the second most popular mobile operating system globally after Android.\r\n \r\nHistory Of iOS\r\nBack in 2005, when Steve Jobs is cooking up his plans to create an iPhone, he had a choice to either enlarge the iPod or \u201cshrink the Mac\u201d which would need a great engineering. Although he favored the later approach, he opted for an internal competition between the Macintosh and iPod teams with the Macintosh team winning by creating the iPhone OS.\r\niOS was originally unveiled with the iPhone at the Macworld Conference & Expo on January 9, 2007 and was released in June the same year. At the time of the unveiling, Jobs called it as \u201ciPhone runs OS X\u201d and that it runs desktop application. But when the first iPhone was released, its operating system was renamed as \u201ciPhone OS\u201d.\r\n\r\n\r\n\r\n\r\n \r\nAbout Apple's User Interface\r\nIts interface is based upon direct manipulation in which users can use multi-touch gestures. The control elements of the interface is consists of switches, sliders and buttons. Its interactions are swipe, tap, pinch and reverse pinch all of which has specific definition on the system Some of the applications respond to shaking the device or rotating the screen (either portrait or landscape).\r\nDuring the first run of iPhones, third-party native apps were not supported. According to Steve Jobs, developers could build applications through the web Safari browser and that it would behave like native apps on the iPhone. It wasn\u2019t until March 2008 that they announced that iPhone has Software Development Kit that developers can use. \r\nIn July 2008, the iOS App Store was opened with an initial 500 applications available. Since then, the number of applications available on the iOS App Store has been increasing and is projected to reach 5 million apps by 2020. \r\nApple has been calling their mobile system iPhone OS but not until June 2010 when Apple rebranded it to iOS. Even though the trademark iOS has been used by another company, Cisco, Apple was able to licensed the iOS trademark to avoid potential lawsuits.\r\n \r\nIOS Software Updates\r\nSince the creation of iOS in 2007, it has undergone a lot of updates. Starting from iPhone OS 1 to its latest version iOS 13, major updates has been made to accommodate the evolution of iPhone, iTouch and iPad. Updates for iOS were first released through the iTunes software and since iOS 5, via over-the-air. This updates are provided annually to support the upcoming devices of Apple. Just recently, Apple has introduced a separate operating system for its iPad, the iPadOS.\r\n \r\nFeatures Of iOS\r\n \r\nHome Screen\r\n\r\n\r\n \r\niOS\u2019 home screen displays application icons and a dock, which allow users to pin their most used apps at the bottom. Its home screen appears whenever the users unlocks the iPhone or whenever the \u201chome\u201d button was pressed.\u00a0\r\nSpotlight was introduced in iPhone OS 3 where users can search media, emails, contacts, messages, reminders, calendar events and similar content. In iOS 7, spotlight can be accessed by pulling down anywhere in the home screen. \r\nIt wasn\u2019t until iOS 4 when the home screen background can be customized. Before this, the screen background could only be changed through jail breaking. Also at this same version, folders, which can be created by dragging an application on top of another and from then on, you can add more apps in the folder via the same procedure.\r\nBefore iOS 5, notifications were delivered through a modal window and users won\u2019t be able to access it once dismissed. But in the iOS 5 update, Apple introduced Notification Center, where users can access their history notification and has the option to tap or clear it.\r\n \r\nAccessibility\r\niOS has various accessibility features to cater users with vision and hearing disabilities. Its accessibility feature, VoiceOver, gives user a reading of what\u2019s on their screen and navigate the device through gestures. \r\nWhen iOS 7 was released, Apple developed a technology to incorporate Bluetooth in the system. This allowed users to connect third-party equipment on iPhone and iPad for streaming audio directly to their ears.\r\n \r\nMultitasking\r\nApple first released multitasking for iOS in June 2010. During this time, multitasking is supported through seven background APIs (Application Programming Interface) which includes; background audio, push notification, voice over IP, local notifications, task completion, background location, and fast app switching. In the iOS 5 update, three new background APIs were introduced; Newsstand, external accessory and Bluetooth accessory.\r\nIn the later iOS versions, users can switch applications by double-clicking the home button. You can also end tasks by briefly holding the icon of application and tapping the red minus circle but later switched to simply swiping them upwards off the screen.\r\n \r\nSiri\r\nOne of the most popular features of iOS is its intelligent personal assistant, Siri. It was first integrated on iPhone 4S, where Siri uses voice queries to answer to answer questions, make recommendations and perform certain actions through the use of internet. Sire can perform wide range of user commands including phone actions, searching the internet, navigating areas and a lot more.\r\n \r\nGame Center\r\nIt also features a game center where users can invite friends to play a game, start a multiplayer game through matchmaking, track game achievements, and compare high scores through a leader board. It is an online multiplayer \u201csocial gaming network\u201d released by Apple.\r\n \r\nBonus: Jailbreaking\r\nJailbreaking\u2019s first use was to bypass Apple\u2019s purchase mechanism for App Store\u2019s native application. But when iOS App Store was introduced, the use for jailbreaking was changed. Users jailbreak their Apple device to install custom device themes, modify their home screens and gain filesystem access. \r\nOn some Apple devices, jailbreaking also made it possible for users to install alternative operating systems. These include Linux, Kernel and Android. Users primarily use it due to limitations by iOS. But since on the later updates, users aren\u2019t that compelled to jailbreak their phones anymore.\r\nFor everything you need to know about the latest iOS 13, click here.
