Tablet
A tablet computer, commonly shortened to tablet, is a mobile computer with a touchscreen display, circuitry, and battery in a single device. Tablets come equipped with sensors, including cameras, a microphone, and an accelerometer, and the touchscreen display uses the recognition of finger or stylus gestures replacing the usage of the mouse and keyboard. They usually feature on-screen, pop-up virtual keyboards for typing. Tablets may include physical buttons for basic features such as speaker volume and power, and ports for network communications and battery charging. Tablets are typically larger than smartphones or personal digital assistants at 7 inches (18 cm) or larger, measured diagonally. Tablets can be classified according to the presence and physical appearance of keyboards. Slatesand booklets do not have a physical keyboard and typically feature text input performed through the use of a virtual keyboard projected on a touchscreen-enabled display. Hybrids, convertibles and 2-in-1's do have physical keyboards (although concealable or detachable), yet these devices typically also make virtual keyboards available.
