The iPad is a tablet computer designed and developed by Apple. It is particularly marketed as a platform for the use of audio and visual media such as books, periodicals, movies, music, and games, as well as web content. At about 700 grams, its size and weight are between most contemporary smartphones and laptop computers. Apple sold 3 million iPads in the first 80 days after its April 2010 release.
The iPad runs the same operating system as the previously introduced iPod Touch and iPhone. However until fall 2010 it runs a slightly older version than the iPhone. It can run its own specific applications as well as those developed originally for the iPhone. Without modification, it will only run programs approved by Apple and distributed via its online store.
Like iPhone and iPod Touch, the iPad is controlled by a Multitouch Display sensitive to up to eleven fingers — a break from most previous tablet computers, which used a pressure-triggered stylus. The iPad uses Wi-Fi or a 3G mobile data connection to browse the Internet, load and stream media, and install software. A USB cable is required to sync the iPad with iTunes on a personal computer, by which the device is managed.
Screen and input: The iPad's touchscreen display is a 25 cm (9.7 in) liquid crystal display (1024 × 768 pixels) with fingerprint-resistant and scratch-resistant glass. Like the iPhone, the iPad is designed to be controlled by bare fingers; normal gloves and styli that prevent electrical conductivity may not be used, although there are special gloves and styli designed for this use.
Power and battery: iPad in the iPad Keyboard DockThe iPad uses an internal rechargeable lithium-ion polymer battery. The batteries are made in Taiwan by Simplo Technology, which makes 60% of them, and Dynapack International Technology. The iPad is designed to be charged with a high current (2 amperes) using the included USB 10 W power adapter.
Storage: The iPad was released with three options for internal storage size: a 16, 32, or 64 GB flash drive. All data is stored on the flash drive and there is no option to expand storage. Apple sells a camera connection kit with an SD card reader, but it can only be used to transfer photos and videos.
Software: Like the iPhone, with which it shares a development environment (iPhone SDK, or software development kit, version 3.2 onwards), the iPad only runs its own software, software downloaded from Apple's App Store, and software written by developers who have paid for a developer's license on registered devices. The iPad runs almost all third-party iPhone applications, displaying them at iPhone size or enlarging them to fill the iPad's screen. Developers may also create or modify apps to take advantage of the iPad's features.
