About IOS in brief
iOS is a mobile operating system created and developed by Apple Inc. exclusively for its hardware. It is the operating system that powers many of the company’s mobile devices, including the iPhone and iPod Touch. The current stable version, iOS 14, was released to the public on September 16, 2020. 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. The operating system was unveiled with the iPhone at the Macworld Conference & Expo on January 9, 2007, and released in June of that year. The iOS App Store was opened on July 10, 2008 with an initial 500 applications available. In June 2010, Apple rebranded its operating system as iPhone OS to avoid a potential lawsuit from Cisco, which had used IOS on its routers for over a decade. The name IOS had been used by Cisco for a decade for its operating systems, including its routers, switches, and other products. The term also included the versions running on iPads until the name iPadOS was introduced with version 13 in 2019. It’s the world’s second-most widely installed mobile system, after Android, and is the basis for three other operating systems made by Apple: iPadOS, tvOS, and watchOS. Some parts of it are open source under the Apple Public Source License and other licenses. It also includes a mobile version of Safari for web browsing, as well as access to the App Store, iTunes Library, Contacts, and Contacts Notes.
It was also used by the U.S. wireless access provider AT&T to provide wireless access of 3G and 3G S&T was initially the sole provider of wireless access for the iPad. It has since been replaced by Wi-Fi, and most existing iPhone apps are downloadable via Wi-G service or syn-Fi. The iPhone OS was created by Scott Forstall and Tony Fadell, respectively, in an internal competition, with Forstall winning by creating the iPhone OS. Forstall was also responsible for creating a software development kit for programmers to build iPhone apps, and an App Store within iTunes. Initially, third-party native applications were not supported. In September 2007, Apple announced the iPod Touch, a redesigned iPod based on the iPhone form factor. On January 27,2010, Apple introduced their much-anticipated media tablet, the iPad, featuring a larger screen than the iPhone, and designed for Web browsing, media consumption, and reading, and offering multi-touch interaction with multimedia formats including e-books, music, videos, photos, and video games. The version of iOS that runs on the iPad is version 9, using a screen size of 7-inch using a version 9 of the iPhone 9, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, and 34.
