    A rudimentary one yes.

    What’s WP Super Cache plugin for?

    It creates static HTML copies of your dynamically generated by WordPress output. Those HTML only copies are easier IO and CPU wise for your web server to serve to your visitors.

    What plugins like WP Super Cache do is preserve that HTML output for a time and server that static HTML content to subsequent visitors. That puts less of a load on your web server and results in an overall increase in performance for your visitors.
