iOS (previously named iPhone OS) is an operating system for mobile devices, made and sold by Apple Inc. It is the main operating system of the iPhone, the iPod Touch, and the iPad. It is Apple's mobile operating system for its iPhone, iPod touch, iPad, Apple TV and similar devices. iOS was originally called the iPhone OS but was renamed in 2010 to reflect the operating system’s evolving support for additional Apple devices.[8]

History[change | edit source]

iOS was released in 2007 simply known as OS X for the first generation iPhone. Apple said on January 9, 2007 at a conference that there will be a new product, the iPhone, and it would have a "revolutionary" operation system.[9]

On March 6, 2008, Apple renamed OS X to iPhone OS following the release of the iPhone software development kit.

On July 11, 2008, along with the release of the iPhone 3G, Apple released iPhone OS 2.0, which introduced the App Store.

In June 2009, Apple released iPhone OS 3.0. It was a minor upgrade to iPhone OS 2.0 except it could do a few new things. iPhone OS 3.0 wasn't available for the the first iPhone and iPod Touch and was later available for the iPad when it was released.

In September 2009, Apple renamed "iPhone OS" to "iOS". The trademark "IOS" has been used by the tech company Cisco, so Apple licensed the trademark in order to avoid conflicts.[10]

In mid-2010, Apple also released a significant update, iOS 4.0, which added the ability of multitasking, the option to have a wallpaper for the home screen and gives the user the ability to run several apps at the same time, while the amount of apps are affected by the device's RAM. Not only that, but it also had a more polished design and was the first version of iOS to be available for the iPod Touch for free. Unfortunately, the iPhone 3G and iPod Touch (2nd generation) have limited features, meaning that they can't multitask or have a wallpaper for the home screen.

In October 2011, Apple released iOS 5, which introduced many new features such as the notifications pull-down bar, a free messaging service called iMessage, iCloud, and more. A voice assistant named Siri was also released to the iPhone 4S.

iOS 6 was released on September 21, 2012 with even more features. Siri was released to the iPad (3rd generation), iPod touch (5th generation), and the iPhone 5. YouTube was removed and a YouTube app was added to the App Store. Google Maps was also removed and replaced with Apple Maps.

On September 18, 2013, iOS 7 was released with a new look and many features, and a new feature called "Control Center" where you can control basic settings, music, AirPlay, brightness, flashlight, and more.

App Store[change | edit source]

One of the most important software (app) in iOS is the App Store. The App Store is an electronic market which gives you the ability to buy "apps", small user interface applications. By January 2013, Apple confirmed to have more than 800,000 applications in the app store.[11]
