Static Web Pages Dynamic Web Pages
Pre-built content is same every time the page is loaded. Content is generated quickly and changes regularly.
It uses the HTML code for developing a website.It sends exactly the same response for every request. It uses the server side languages such as PHP,SERVLET, JSP, and ASP.NET etc. for developing a application.
The content is only changed when someone publishes and updates the file (sends it to the web server). The page contains "server-side" code which allows the server to generate the unique content when the page is loaded.
