The terminology can get confusing, but if you use the Joomla constructs of static and dynamic, which seems to be a quasi standard, then you cannot go far wrong.
Typically, a static page is an HTML page who's content rarely/never changes, eg., an About page on the website.
A dynamic page would be one who's content is driven by Db, or other, info in order to generate it. Such as an inventory browse or report.
