Specifications of Tablet PC


Welcome to Know prices
 Most PC computer capabilities, popular, typical tablet computers purchased in the last year include wireless Internet browsing functions, potential cell phone functions, GPS navigation, and video camera functions, weigh around two or three pounds (1-1.5 kilograms) and typically have a battery life of three to ten hours. The Tablet PC and the associated special operating software is an example of pen computing technology, and thus the development of tablets has deep historical roots. Tablet PC are mainly based on the x86 IBM-PC architecture and are fully functional personal computers employing a slightly modified personal computer OS supporting their touch-screen, instead of a traditional display, mouse and keyboard. A typical tablet personal computer needs to be stylus driven, because operating the typical desktop based OS requires a high precision to select GUI widgets, such as a close window button.

The device implementation differs from more traditional PCs or laptops, Tablet PC are disrupting the current vendor sales by weakening traditional laptop PC sales in favor of the current tablet computers. This is even truer of the "finger driven multi-touch" interface of the more recent tablet computers, which often emulate the way actual objects, behave. Capacitive touch screens tend to be less accurate, but more responsive than resistive screens. Because they require a conductive material, such as a finger tip, for input, they are not common among Tablet PCs but are more prominent on the smaller scale "tablet computer" devices for ease of use, which generally do not use a stylus, and need multi-touch capabilities. An accelerometer is a device that detects the physical movements of the tablet. This allows greater flexibility of use since tablets do not necessarily have a fixed direction of use. The accelerometer can also be used to detect the orientation of the tablet relative to the horizontal plane, but can also detect movement of the tablet, both of which can be used as an alternative control interface for a tablet's software.
