For those who do not know, a widget is a snippet of code and can be anything that can be embedded within a page of HTML, i.e. a web page. A widget adds some content to that page that is not static. Generally widgets are third party originated, though they can be home made. Widgets are also known as modules, and plug-ins.Applications can be integrated within a third party website by the placement of a small snippet of code. The code brings in ‘live’ content – advertisements, links, images – from a third party site without the web site owner having to update.
End users can utilize Web Widgets to enhance a number of web-based hosts, or drop targets. Categories of drop targets include social networks, blogs, wikis and personal homepages.
