Tablet Computer
A tablet computer, commonly shortened to tablet, is a mobile device, typically with a mobile operating system and touchscreen display processing circuitry, and a rechargeable battery in a single, thin and flat package. Tablets, being computers, have similar capabilities, but lack some input/output (I/O) abilities that others have. Modern tablets largely resemble modern smartphones, the only differences being that tablets are relatively larger than smartphones, with screens or larger, measured diagonally, and may not support access to a cellular network. Unlike laptops (which have traditionally run off operating systems usually designed for desktops), tablets usually run mobile operating systems, alongside smartphones. The touchscreen display is operated by Gesture recognition, gestures executed by finger or digital pen (stylus), instead of the Computer mouse, mouse, touchpad, and Keyboard (computing), keyboard of larger computers. Portable computers can be classified according ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Modern mobile devices often emphasize wireless networking, to both the Internet and to other devices in their vicinity, such as headsets or in-car entertainment systems, via Wi-Fi, Bluetooth, cellular networks, or near-field communication. Characteristics Device mobility can be viewed in the context of several qualities: * Physical dimensions and weight * Whether the device is mobile or some kind of host to which it is attached is mobile * What kind of host devices it can be bound with * How devices communicate with a host * When mobility occurs Strictly speaking, many so-called mobile devices are not mobile. It is the host that is mobile, i.e., a mobile human host carries a non-mobile smartphone device. An example of a true mobile computing ...
