WordPress is coded in a programming language called PHP which accesses http://www.wpcouponcode.net/engine.htm the content from a MySQL database. As it is continually extracting packets of information from the server and elsewhere, WordPress may need more memory that a simple static HTML site. You may need to decide between purchasing a managed wp or an unmanaged wp account. With an unmanaged site you are on your own. You have to install the updates for every latest version.
