The iPad is a tablet computer designed and marketed by Apple (Apple Inc.) for Internet browsing, media consumption, gaming, and light content creation. Released in April 2010, it established a new class of devices between smartphones and laptops. As of May 3, 2010, Apple had sold 1 million iPads.

Similar to the older (and smaller) iPod Touch and iPhone, the iPad runs a modified version of the iPhone OS and is controlled by a multi-touch LCD sensitive to fingertips, instead of a stylus (stylus (computing)) as with earlier tablet computers. It runs iPad-specific applications as well as those written for the iPhone and iPod touch, including e-book readers.

The iPad uses Wi-Fi or a 3G data connection to browse the Internet, load and stream media, and install software. A USB cable is required to sync (File synchronization) the iPad with iTunes on a personal computer.
