A tablet computer, or simply tablet, is a one-piece, mobile version of a personal computer, primarily operated by touchscreen (the user's finger essentially functions as the mouse and cursor, removing the need for the physical [i.e., mouse & keyboard] hardware components necessary for a desktop or laptop computer; and, an onscreen, hideable virtual keyboard is integrated into the display). Available in a variety of sizes, even the smallest's touchscreens are much larger than those of a smart phone or personal digital assistant.[1][2] A tablet computer may be connected to a keyboard with a wireless link or a USB port. Convertible notebook computers have an integrated keyboard that can be hidden by a swivel joint or slide joint, exposing only the screen for touch operation. Hybrids have a detachable keyboard so that the touch screen can be used as a stand-alone tablet. Booklets include dual-touchscreens, and can be used as a notebook by displaying a virtual keyboard in one of them.
