Tablet PCs

A tablet computer, or simply tablet, is a one-piece mobile 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 and 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. 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.
