Online puzzle Tablet computer
A tablet computer, commonly shortened to tablet, is a portable personal computer, typically with a mobile operating system and LCD touchscreen display processing circuitry, and a rechargeable battery in a single thin, flat package. Tablets, being computers, do what other personal computers do, but lack some I/O capabilities that others have. Modern tablets largely resemble modern smartphones, the only differences being that tablets are relatively larger than smartphones, with screens 7 inches (18 cm) or larger, measured diagonally, and may not support access to a cellular network.
The touchscreen display is operated by gestures executed by finger or stylus instead of the mouse, trackpad, and keyboard of larger computers. Portable computers can be classified according to the presence and appearance of physical keyboards. Two species of tablet, the "slate" and "booklet", do not have physical keyboards and usually accept text and other input by use of a virtual keyboard shown on their touchscreen displays. Distinct from tablets, 2-in-1 PCs all have physical keyboards, but they are either concealable by folding them back and under the touchscreen ("2-in-1 convertible ") or detachable ("2-in-1 detachable"), but 2-in-1s typically also can display a virtual keyboard on their touchscreens when their physical keyboards are concealed or detached. Some 2-in-1s have processors and operating systems like those of laptops, while having the flexibility of operation as a tablet (See "2-in-1" below for more information ). To compensate for their lack of a physical keyboard, most tablets can connect to independent physical keyboards by wireless Bluetooth or USB.
The form of the tablet was conceptualized in the middle of the 20th century (Stanley Kubrick depicted fictional tablets in the 1968 science fiction film 2001: A Space Odyssey ) and prototyped and developed in the last two decades of that century. In 2010, Apple released the iPad, the first mass - market tablet to achieve widespread popularity.
