A tablet personal computer (tablet PC) is a portable personal computer equipped with a touch screen as a primary input device, and running a modified desktop OS such as android or iOS. The term was made popular as a concept in the years 2000 and 2001, but tablet PCs now refer to any tablet-sized (approx. 7" screen size) personal computer regardless of the operating system.
Incidentally, according to dictionary.com, tablet refers to a number of sheets of writing paper, business forms, etc., fastened together at the edge; pad. Tablet personal computers are mainly based on the x86 IBM-PC architecture and are fully functional personal computers, supporting their touch-screen, instead of a traditional display, mouse and keyboard. A stylus is preferred to operate a tablet computer, because operating the typical desktop based OS requires a high precision to select GUI widgets, such as a close window button.
