A touchscreen is a special type of screen in which the screen not only displays output but also responds to being touched.
A typical example is their use in autotellers at banks. Part of the screen contains information. Other parts may contain a menu. When you touch one of the icons on the screen, the system responds to the associated command.
Another example is to be found in information screens in shopping malls. The lower half of the screen consists of a number of icons representing menu items. If you touch one of these, either information will be displayed in the top half or a sub-menu will appear allowing you to refine your search for information.
PDAs have touch sensitive screens. You would use a special stylus to touch icons on the screen or to write. Character recognition software then converts your writing to input text for the PDA.
