Backend
The backend of a site refers to those parts of a website that are invisible to the ordinary visitor. The backend therefore refers to the database in which information is stored and to the password protected pages that allow specified users to administer the content of the site.

The front end of the site refers to the pages with their associated graphics and content that the casual visitor to the website sees. These pages format the information held in the backend database and presents them for viewing to the site visitor. |
