Description

A tablet computer is a mobile computer with touch-screen display,  circuitry and battery in a single unit. Tablets come equipped with sensors,  including cameras,  a microphone,  an accelerometer and a touchscreen,  with finger or stylus gestures substituting for the use of computer mouse and keyboard. Tablets may include physical buttons (for example: to control basic features such as speaker volume and power) and ports (for network communications and to charge the battery). They usually feature on-screen,  pop-up virtual keyboards for typing. Tablets are typically larger than smart phones or personal digital assistants at 7 inches (18 cm) or larger,  measured diagonally.
