WI DGET TERMINOLOGY in Magento Design

• Frontend Block – an element which creates the visual output either by assigning visual structure or by producing the actual content.

• Magento Widget – a frontend block that implements a special widget interface which allows for having different configuration options per each block instance, and the ability to have multiple independent block instances on pages.

• Magento Widget Instance – a block on a single page or multiple pages which receives its configuration options as defined by a store owner in the backend. The same widget can be added to the frontend multiple times producing multiple instances of the same widget.
Please note that a single widget instance can also be added to multiple pages (with the same configuration options values) and managed  as a single entity.
