Extensibility: A framework can be extended by the user by selective overriding with the user code. Non Modified Framework Code: User can extend the framework but not allow to modify the code of the framework.
  4. 4. Application programing interface is called as API. It is an interface that a software program implements in order to allow other software to interact with it. <ul><li>By using API we can interface with many websites from our website. </li></ul><ul><li>By adding the plug ins into our site we can access the website with the help of general key and secret key. </li></ul><ul><li>We can also copy the code of the API of particular website and paste it into other website and we can use it. </li></ul>API (Application programming interface)
  5. 5. Cascading Style Sheets <ul><li>It displays the HTML elements in stylish way.

  7. 7. JavaScript <ul><li>It is a scripting language in the web and it is an object oriented. It access the objects both in client side & other application. </li></ul><ul><li>Javascript allows user interface and for dynamic web pages. </li></ul><ul><li>We can write functions that are embedded with html. </li></ul><ul><li>Validation of web page input values at the client side. </li></ul><ul><li>Changes the images as the mouse cursor moves over them. </li></ul>
  8. 8. Ajax <ul><li>Asynchronous JavaScript and XML, is a new way for web pages to send and receive data to and from a web site without forcing the user to wait for a new page to load. </li></ul>
  9. 9. Minimal data transfer : By not performing a full post back and sending all form data to the server, the network utilization is minimized and quicker operations occur. In sites and locations with restricted pipes for data transfer, this can greatly improve network performance. Limited processing on the server: server is not required to process all form elements . By sending only the necessary data, there is limited processing on the server. There is no need to process all form elements,process the view state, send images back to the client, and no need to send a full page back to the client.
