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 have 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 with screens or larger, measured diagonally.
