Basically there are two types of web pages :-

  1. Static Web Pages:- Static websites consist of a fixed number of pre-rendered web pages. It doesn't reflect any changes in user action.Static web pages are usually built independently, without connecting to a database.

  2. Dynamic Web Pages:- Dynamic webpages generates pages in real-time. The flexibility of the content and structure makes is possible to what a user experience based on their request or the browser they use. Dynamic websites generate and display content based on the actions taken by a user.

Difference between static and dynamic web pages.

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.
