A tablet personal computer (tablet PC) is a portable personal computer equipped with a touchscreen as a primary input device[1] and designed to be operated and owned by an individual.[2] The term was made popular as a concept presented by Microsoft in 2001,[3] but tablet PCs now refer to any tablet-sized personal computer, regardless of the operating system.[4]

Unlike laptops, tablet personal computers may not be equipped with a keyboard, in which case they use a virtual onscreen substitute. All tablet personal computers have a wireless adapter for Internet and local network connection. Software applications for tablet PCs include office suites,[5] web browsers,[6] games and a variety of applications. However, since portable computer hardware components are low powered, demanding PC applications may not provide an ideal experience to the user.[7]


System Software

Microsoft Windows

Following Windows for Pen Computing, Microsoft has been developing support for tablets running Windows under the Microsoft Tablet PC name.[8] According to a 2001 Microsoft definition[9] of the term, "Microsoft Tablet PCs" are pen-based, fully functional x86 PCs with handwriting and voice recognition functionality. Tablet PCs use the same hardware as normal laptops but add support for pen input. For specialized support for pen input, Microsoft released Windows XP Tablet PC Edition. Today there is no tablet specific version of Windows but instead support is built in to both Home and Business versions of Windows Vista and Windows 7. Tablets running Windows get the added functionality of using the touchscreen for mouse input, hand writing recognition, and gesture support. Following Tablet PC, Microsoft announced the UMPC initiative in 2006 which brought Windows tablets to a smaller, touch-centric form factor. This was relaunched in 2010 as Slate PC, to promote tablets running Windows 7, ahead of Apple's iPad launch.[10] Slate PCs are expected to benefit from mobile hardware advances derived from the success of the netbooks.
