Understanding Difference Between Static and Dynamic Websites.

Understanding Static Web Sites

• A static website is stored on a server using HTTP server software
• Client sends HTTP Request with a URL(Uniform Resource Locator)
• Server locates and sends requested file as an HTTP Response

Static Websites Request-Response

• The code & text for each Page is written out separately
• Each Page is saved on the server, just like it is displayed
• Changes must be made by hand in each Page's code

Understanding Dynamic Web Sites

Dynamic Websites Request-Response 

• Application server is installed on the same server as HTTP server software
• Client sends HTTP Request with a URL(Uniform Resource Locator)
• HTTP Server dispatches request to application server 
• Application server dynamically constructs HTTP response
• Each websites Page does not actually exist anywhere
• In one place is the look-and-feel/ layout of the website
• In another place is the content of the website(text,photos)
• When a user wants to see a Page, the server creates it on the fly  

As Dynamic Websites have more advantages than static one so most of the websites you are looking is a dynamic one.

To build a Dynamic Web Application the top three server scripting languages are:

1. ASP.NET : ASP.NET is an open-source server-side web application framework designed for web development to produce dynamic web pages. It was developed by Microsoft to allow programmers to build dynamic websites, web applications, and web services.
   
2. PHP : PHP is a server scripting language, and a powerful tool for making dynamic and interactive Web pages.PHP is a widely-used, free, and efficient alternative to competitors such as Microsoft's ASP.
   
3. JSP : JavaServer Pages (JSP) is a server-side programming technology that enables the creation of dynamic, platform-independent method for building Web-based applications. JSP have access to the entire family of Java APIs, including the JDBC API to access enterprise databases.
