A tablet personal computer or tablet PC is a tablet-sized computer that also has the key features of a full-size personal computer. A tablet PC is essentially a small laptop computer, equipped with a rotatable touch screen as an additional input device, and running a standard PC operating system like Windows or Linux. Tablet PC, a notebook or slate-shaped mobile computer, first introduced by Pen Computing in the early 90s with their Pen Go Tablet Computer and popularized by Microsoft.
Mobility is considered to be one of the best advantages of the tablet PC. Both light and small tablet PC gives you an opportunity to work in absolutely any situation. You have to know that all the tablet PCs use touch screen technology. This technology allows inputting data on the screen you are working on. And this is one of many reasons why these devices are so small. To type you have to handwrite with a stylus or use a virtual keyboard.
Tablet PCs are regular PCs. Some developers and users still think that Tablet PCs somehow run on a special operating system, such as Windows CE, which is not the case. (Fortunately, the group that holds that belief seems to be shrinking.) The first generation of Tablet PCs (pre- Windows Vista) runs on a special version of Windows XP, called the Windows XP Tablet PC Edition. This is a super-set of Windows XP, which means that absolutely everything Windows XP has to offer is also available on Tablet PCs. In addition, there are components that are specific to Tablet PCs, such as Digital Ink collection components, and also some Tablet PC- specific applications, such as Windows Journal.
