iPad is an iOS-based line of tablet computers designed and marketed by Apple Inc. The user interface is built around the device's multi-touch screen, including a virtual keyboard. The iPad includes built-in Wi-Fi and cellular connectivity on select models. The first generation established design precedents, such as the 9.7-inch screen size and button placement, that have persisted through all models.
