Sitecore Standard Template contains the Fields which define how Sitecore should manage an Item, such as when it should be published, which workflow it is in, which users should be allowed to access it, and so on.
When an Item is selected in the Content Editor, you can see the sections of its template in the right pane. Take a look at the picture below. All the sections outlined by the red color are defined in the Standard Template.
Every template inherits sections from its base template, defined in the _Base template field. So, if you want to implement the sections shown in the picture above, your template should inherit from the Standard template (or from the template which inherits from the Standard template).
The Standard template allows Sitecore administrators to restrict access to particular operations for low-privileged Users. For example, the Editor User supplied with the default Sitecore installation can only access the Data and Publishing sections.Click here to read more about setting rights on the Standard template sections.
