A tablet PC is a laptop or slate-formed mobile computer that is outfitted with a touchscreen or screen that can be controlled with a digital pen or stylus, or via finger touch. A tablet PC does not require a keyboard or mouse. End-users can directly key in data on a tablet PC. It also offers greater mobility than a conventional laptop.
A tablet computer, or simply tablet, is a medium-sized personal mobile computer integrated into a flat touch screen and primarily using stylus, digital pen or fingertip input along with a virtual onscreen keyboard in lieu of a physical keyboard.
As of 2010, two distinctly different types of tablet computing devices exist.
Firstly, older tablet personal computers are mainly x86 based, and are fully functional personal computers employing a slightly modified personal computer OS (Like Windows or Ubuntu Linux) 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 the close window button.
Since mid-2010, new tablet computers with mobile operating systems forego the Wintel paradigm, have a different interface and have created a new type of computing device. These mobile OS tablet computer devices are normally finger driven and use multi-touch capacitive touch screens, instead of the simple resistive touchscreens of typical stylus driven systems (also a standard external USB keyboard can be used). First of these was the iPad, with Samsung Galaxy Tab and others following. In foregoing the x86 precondition (a requisite of Windows compatibility), the new class of tablet computers use a version of an ARM architecture processor heretofore used in portable equipment (e.g., MP3 players and cell phones) now powerful enough (especially with the introduction of the ARM Cortex family) for tasks such as internet browsing, light production work and gaming.
A tablet personal computer (tablet PC) is a portable personal computer equipped with a touchscreen as a primary input device, and running a (modified) classic desktop OS. designed to be operated and owned by an individual. The term was made popular as a concept presented by Microsoft in 2000 and 2001 but tablet PCs now refer to any tablet-sized personal computer regardless of the (desktop) operating system.
