Object Oriented Programming (OOP) Programming technique based on using classes, objects, and methods - an approach to designing modular reusable software systems. Joomla is based on OOP. Solid understanding on OOP is a key plus when working with Joomla programs.
Editor A user level on a Joomla site that by default can access only the front end. Editors have privileges to post and edit content, but no permission for publishing content.
Wrapper A Joomla module that allows you to “wrap” directly other Web sites for display on your Joomla site at a specific location as determined by the Module Position and the Pages Items section. The web page is inserted as an Inline Frame (also called an Iframe) into the web site layout template.
