Bread Crumbs

When i heard the words "BREAD CRUMBS" the first thing that came into my mind was eating bread..
So what it is really???

Breadcrumbs or breadcrumb trail is a navigation aid used in user interfaces.
It gives users a way to keep track of their location within programs or documents.

eg : Home->Products->Mobile->Nokia->N72

The term comes from the trail of breadcrumbs left by Hansel and Gretel in the popular fairytale.
