What is statics page and dynamic …

Static Web Pages: These pages display the exact same information whenever anyone visits it. Static Web pages do not have to be simple plain text. They can feature detailed multimedia design and even videos. However, every visitor to that page will be greeted by the exact same text, multimedia design or video every time he visits the page until you alter that page's source code.

Dynamic Web Pages: These are capable of producing different content for different visitors from the same source code file. The website can display different content based on what operating system or browser the visitor is using, whether she is using a PC or a mobile device, or even the source that referred the visitor. A dynamic Web page is not necessarily better than a static Web page. The two simply serve different purposes.
