Answer:

Static web pages always look the same and the content never changes unless you load a new page or you change the page yourself or request your web designer to make changes and upload the new version of the web page to the web server.

Dynamic pages do the opposite, they can change every time they are loaded (without you having to make those changes) and they can even change their content based on what your website visitors do. The dynamic page can be created as a direct result of your website visitor requesting information.

Dynamic pages are created using active information from a database. Instead of creating the usual static html web pages in advance and uploading these to your web space in readiness for your website visitors. The web pages are instantly created when the software "interrogates" your database and the necessary information and pictures are returned in the form of a web page.
