Desktop Widgets
A software widget is a generic type of software application comprising portable code intended for one or more different software platforms. The term often implies that either the application, user interface, or both, are light, meaning relatively simple and easy to use, as exemplified by a desk accessory or applet, as opposed to a more complete software package such as a spreadsheet or word processor.
