Generally a PDA is a very small computer. This means that you can install software onto it and save work to it. PDAs are usually upgradeable, which means that the user can add extra memory and peripheral devices to it. One of the most common devices that is added to a PDA is a Global Positioning System (GPS) to help car drivers find where they are going.

Most modern PDAs do not have a built-in keyboard, but they do have touch-sensitive screens on which a virtual keyboard appears. The user writes using a stylus to touch the relevant letters. The touch screen allows the user to control the PDA in a similar way to using a mouse on a PC.
