How WordPress Caching Works:
Caching refers to a temporary static file that is stored in order to speed up the retrieval of it’s data. This is helpful in cases where content is displayed as HTML but has scripts like PHP gathering information from the database.
Having cached versions of html files being delivered speeds up the time that it takes for the server to display a page.
