Tablet computer

A tablet computer, commonly shortened to tablet, is a thin, flat mobile computer with a touchscreen display, which is usually in color, processing circuitry, and a rechargeable battery in a single device. Tablets often come equipped with sensors, including digital cameras, a microphone, and an accelerometer, so that images on screens are always displayed upright. The touchscreen display uses the recognition of finger or stylus gestures to replace the mouse, trackpad and keyboard used in laptops.

Tablets are typically larger than smartphones or personal digital assistants with screens 7 inches (18 cm) or larger, measured diagonally. However much of a tablet's functionality resembles that of a modern smartphone, like having a virtual keyboard or running a dedicated 'mobile' operating system.

Tablets can be classified according to the presence and physical appearance of keyboards. Slates and booklets do not have a physical keyboard, and text input and other input is usually entered through the use of a virtual keyboard shown on a touchscreen-enabled display. Hybrids, convertibles, and 2-in-1s do have physical keyboards (although these are usually concealable or detachable), yet they typically also make use of virtual keyboards. Some 2-in-1s have processors and operating systems like a full laptop, whilst having the flexibility of being used as a tablet. Most tablets can use separate keyboards connected using Bluetooth.
