What does a Sitecore Template define?

A Sitecore Template is a fundamental component of the Sitecore content management system, specifically used to define the structure and fields of an item. It acts as a blueprint for creating content items within Sitecore. This means that the template specifies what fields (such as text fields, image fields, etc.) an item based on that template will have, as well as the types of content that can be created from it.

By providing a structured way to organize content, templates enable developers and content authors to maintain consistency and manage content more effectively. They determine how data is organized and what information will be captured for each item, thereby ensuring that all necessary attributes for a specific type of content are accounted for during item creation.

While other options like the style of a webpage, the navigation layout of a site, and user access levels are important aspects of Sitecore, they are not defined by a template directly. Templates focus specifically on the data architecture rather than aesthetic or functional design elements that pertain to a site's presentation or security framework.
