What is a Template?
The content management system called Joomla uses Templates for the design and layout of what you see in your browser. Template files can be very simple or complex depending on how they are developed and what functionality is included. Your template files may need to be modified further depending on what components or modules you use on your Joomla Website.
Joomla is just one example, now a days most websites are designed using some form of template even if it is just a centralized collection of CSS files.
The reason for this is simple, having a template makes it easy to do site wide updates and changes vs having to edit each page individually. This obviously saves time and assures consistency across the website.
