A slate PC is a slate-formed computer, also known as a tablet, that has a touch screen that is controlled by use of the fingers, digital pen or stylus. Data is directly keyed in on the touch screen display and the signal processed to output a recognizable response. They are in use for industrial and entertainment use due to a number of features. The different categories of slate PCs vary according to applications, sizes and unique features.

One type of tablet available today is the slate tablet PC. This type is very similar to the original writing slate. It does not have a keyboard attached. The mode of data input includes handwriting recognition, digital pen and stylus, as well as finger touch. They have ports as well as wireless provision for connection to a keyboard.
