IPod Touch in the context of "Apple silicon"

iOS (formerly iPhone OS) is a mobile operating system created and developed by Apple for its iPhone line of smartphones. It was unveiled in January 2007 alongside the first-generation iPhone, and was released in June 2007. Major versions of iOS are released annually; the current stable version, iOS 26, was released to the public on September 15, 2025.

Besides powering iPhone, iOS is the basis for three other operating systems made by Apple: iPadOS, tvOS, and watchOS. iOS formerly also powered iPads until iPadOS was introduced in 2019 and the iPod Touch line of devices until its discontinuation. iOS is the world's second most widely installed mobile operating system, after Android. As of December 2023, Apple's App Store contains more than 3.8 million iOS mobile apps.

An LED-backlit LCD is a liquid-crystal display that uses LEDs for backlighting instead of traditional cold cathode fluorescent (CCFL) backlighting. LED-backlit displays use the same TFT LCD (thin-film-transistor liquid-crystal display) technologies as CCFL-backlit LCDs, but offer a variety of advantages over them.

Televisions that use a combination of an LED backlight with an LCD panel are sometimes advertised as LED TVs, although they are not truly LED displays.

FarmVille is a series of agriculture-simulation social network games developed and published by Zynga beginning in 2009. It is similar to Happy Farm and Farm Town. Its gameplay involves various aspects of farmland management, such as plowing land, planting, growing, and harvesting crops, harvesting trees and raising livestock. The sequels FarmVille 2 and FarmVille 3 were released in 2012 and 2021.

The game was available as an Adobe Flash application via the social networking website Facebook and Microsoft's MSN Games. It was briefly available as a mobile app for the iPhone, iPod Touch, and iPad in 2010. The game is free to play, but to progress quickly, players are encouraged to spend Farm Cash (in FarmVille) or Farm Bucks (in FarmVille 2), which are purchasable with real-world currency. FarmVille was thus one of the first major freemium games.

The App Store is an app marketplace developed and maintained by Apple, for mobile apps on its iOS and iPadOS operating systems. The store allows users to browse and download approved apps developed within Apple's iOS SDK. Apps can be downloaded on the iPhone, iPod Touch, or iPad, and some can be transferred to the Apple Watch smartwatch or 4th-generation or newer Apple TVs as extensions of iPhone apps.

The App Store opened on July 10, 2008, with an initial 500 applications available. The number of apps peaked at around 2.2 million in 2017, but declined slightly over the next few years as Apple began a process to remove old or 32-bit apps. As of 2024, the store features more than 1.9 million apps.

Siri (/ˈsɪri/ SEER-ee) is a virtual assistant and chatbot purchased, developed, and popularized by Apple Inc., which is included in the iOS, iPadOS, watchOS, macOS, Apple TV, audioOS, and visionOS operating systems. It uses voice queries, gesture based control, focus-tracking and a natural-language user interface to answer questions, make recommendations, and perform actions by delegating requests to a set of Internet services. With continued use, it adapts to users' individual language usages, searches, and preferences, returning individualized results.

Siri is a spin-off from a project developed by the SRI International Artificial Intelligence Center. Its speech recognition engine was provided by Nuance Communications, and it uses advanced machine learning technologies to function. Its original American, British, and Australian voice actors recorded their respective voices around 2005, unaware of the recordings' eventual usage. Siri was released as an app for iOS in February 2010. Two months later, Apple acquired it and integrated it into the iPhone 4s at its release on 4 October 2011, removing the separate app from the iOS App Store. Siri has since been an integral part of Apple's products, having been adapted into other hardware devices including newer iPhone models, iPad, iPod Touch, Mac, AirPods, Apple TV, HomePod, and Apple Vision Pro.

iOS 12 is the twelfth major release of the iOS mobile operating system developed by Apple. Aesthetically similar to its predecessor, iOS 11, it focuses more on performance than on new features, quality improvements and security updates. Announced at the company's Worldwide Developers Conference on June 4, 2018, iOS 12 was released to the public on September 17, 2018. It was succeeded for the iPhone and iPod Touch by iOS 13 on September 19, 2019, and for the iPad by iPadOS 13 on September 24, 2019. Security updates for iOS 12 continued for four years after the releases of iOS 13 and iPadOS 13 for devices unable to run the newer versions. The last update, 12.5.7, was released on January 23, 2023.

Lightning is a proprietary computer bus and power connector, created and designed by Apple Inc. It was introduced on September 12, 2012, in conjunction with the iPhone 5, to replace its predecessor, the 30-pin dock connector, and phased out during 2024–2025, concluding with the withdrawal of the iPhone 14 from sale.

The Lightning connector is used to connect legacy Apple mobile devices like iPhones, iPads, and iPods to host computers, external monitors, cameras, USB battery chargers, and other peripherals. Using 8 pins instead of 30, Lightning is much smaller than its predecessor. The Lightning connector is reversible. The plug is indented on each side to match up with corresponding points inside the receptacle to retain the connection.
