A web page can cotain huge information including text, graphics, audio, video and hyper links. These hyper links are the link to other web pages.
Collection of linked web pages on a web server is known as website. There is unique Uniform Resource Locator (URL) is associated with each web page.
Static Web page
Static web pages are also known as flat or stationary web page. They are loaded on the client’s browser as exactly they are stored on the web server. Such web pages contain only static information. User can only read the information but can’t do any modification or interact with the information.
Static web pages are created using only HTML. Static web pages are only used when the information is no more required to be modified.
Dynamic Web page
Dynamic web page shows different information at different point of time. It is possible to change a portaion of a web page without loading the entire web page. It has been made possible using Ajax technology.
Server-side dynamic web page
It is created by using server-side scripting. There are server-side scripting parameters that determine how to assemble a new web page which also include setting up of more client-side processing.
Client-side dynamic web page
It is processed using client side scripting such as JavaScript. And then passed in to Document Object Model (DOM).
Scripting Laguages
Scripting languages are like programming languages that allow us to write programs in form of script. These scripts are interpreted not compiled and executed line by line.
Scripting language is used to create dynamic web pages.
Client-side Scripting
Client-side scripting refers to the programs that are executed on client-side. Client-side scripts contains the instruction for the browser to be executed in response to certain user’s action.
Client-side scripting programs can be embedded into HTML files or also can be kept as separate files.
Following table describes commonly used Client-Side scripting languages:
| S.N. | Scripting Language Description |
|---|
| 1. | JavaScript
It is a prototype based scripting language. It inherits its naming conventions from java. All java script files are stored in file having .js extension. |
| 2. | ActionScriptIt is an object oriented programming language used for the development of websites and software targeting Adobe flash player. |
| 3. | Dart
It is an open source web programming language developed by Google. It relies on source-to-source compiler to JavaScript. |
| 4. | VBScript

Server-side Scripting
Sever-side scripting acts as an interface for the client and also limit the user access the resources on web server. It can also collects the user’s characteristics in order to customize response.
Following table describes commonly used Server-Side scripting languages:
| S.N. | Scripting Language Description |

| 3. | ASP.net
It is used to develop dynamic websites, web applications, and web services. |
| 4. | Java
Java Server Pages are used for creating dynamic web applications. The Java code is compiled into byte code and run by Java Virtual Machine (JVM). |
| 5. | Python
It supports multiple programming paradigms such as object-oriented, and functional programming. It can also be used as non-scripting language using third party tools such as Py2exe or Pyinstaller. |
| 6. | WebDNA
