Windows 8 is a version of Microsoft Windows (an operating system developed by Microsoft) for use on personal computers, including home and business desktops, laptops, tablets, and home theater PCs. Development of Windows 8 started before the release of its predecessor, Windows 7, in 2009. It was announced at CES 2011, and followed by the release of three pre-release versions from September 2011 to May 2012. The operating system was released to manufacturing on August 1, 2012, and was released for general availability on October 26, 2012.[3] Windows 8 uses version 6.2 of the Windows NT kernel.
Windows 8 introduces significant changes to the operating system's platform, primarily focused towards improving its user experience on mobile devices such as tablets to better compete with other mobile operating systems like Android and Apple's iOS.[4] Windows 8 features a new touch user interface and shell based on Microsoft's "Metro" design language, featuring a new Start screen with a grid of dynamically updating tiles that represent applications. The Start screen replaces the "Start menu" of earlier Windows versions. There is a new app platform with an emphasis on touchscreen input, and the new Windows Store to obtain and/or purchase applications to run on the operating system.
In addition, Windows 8 takes advantage of new or emerging technologies like USB 3.0, 4Kn Advanced Format, near field communications, cloud computing, and the low-power ARM architecture. It includes new security features such as built-in antivirus capabilities, a new installation process optimized for digital distribution, and support for secure boot (a UEFI feature which allows operating systems to be digitally signed to prevent malware from altering the boot process). Synchronization of certain apps and settings between multiple devices is supported.
Windows 8 was released to mixed reception. Although reaction towards its performance improvements, security enhancements, and improved support for touchscreen devices was positive, the new user interface of the operating system has been widely criticized for being potentially confusing and difficult to learn (especially when used with a keyboard and mouse instead of a touchscreen). Despite these shortcomings, 60 million Windows 8 licenses have been sold through January 2013. This includes upgrades and sales to OEMs for new PCs.[5]
Windows 8.1 is scheduled for release in late 2013 and, according to Microsoft, will change "key aspects" of how Windows 8 is used,[6] including the reinstatement of the Start button.[7]

| List of iPhone models |
An iPhone can shoot video (though this was not a standard feature until the iPhone 3GS), take photos, play music, send and receive email, browse the web, send texts, and receive visual voicemail. Other functions—games, reference, GPS navigation, social networking, etc.—can be enabled by downloading apps; as of 2012, the App Store offered more than 775,000 apps by Apple and third parties.[17]
There are six generations of iPhone models, each accompanied by one of the six major releases of iOS. The original iPhone was a GSM phone, and established design precedents, such as screen size and button placement, that have persisted through all models. The iPhone 3G added 3G cellular network capabilities and A-GPS location. The iPhone 3GS added a faster processor and a higher-resolution camera that could record video at 480p. The iPhone 4 featured a higher-resolution 960 × 640 "retina display", a higher-resolution rear-facing camera and a lower-resolution front-facing camera for video calling and other apps.[18] The iPhone 4S added an 8-megapixel camera with 1080p video recording, a dual-core processor, and a natural language voice control system called Siri.[19][20][21] iPhone 5 features the new A6 processor, holds a 4-inch Retina display that is larger than its predecessor's 3.5-inch display, and replaces the 30-pin connector with an all-digital Lightning connector.
For some years, Apple and its manufacturing contractor Foxconn have received criticism due to poor working conditions at the assembly plant in China.[22][23][24][25][26][27]
