widget is usually used for code snipers (what is code snippets?) or little application or program you can add to a site to make it perform some function the site was probably not designed for originally, for example, if you visit my blog
www.temi.co.uk , on the right hand side you will see a Technocrati "widget" which tells you information technocrati have about my blog.
Hope this makes thing clearer for you?
Please fell free to ask as many questions as you like
