What is the name of the programming methodology for the Web that enables Web applications to interact with users in much the same way they do with desktop applications?
AJAX-
Ajax (Asynchronous JavaScript and XML) is a programming methodology for the Web that enables Web applications to interact with users in much the same way they do with desktop applications. Ajax allows you to create interactive Web applications using HTML, CSS, the Document Object Model (DOM), JavaScript and XMLHttpRequest.
Wiki is a page or collection of Web pages that can be viewed and modified by anybody with a Web browser and access to the Internet. A mashup is a Web page that integrates content and scripts from multiple Websites to create new applications. Folksonomy is the practice of categorizing online content through tags.
For more information, see Internet Business Associate v2.0, Lesson 2: Internet Communication, section "Modern Web Technologies."
Additional Information: You can use Ajax to create dynamic and interactive Web pages without the need to refresh or reload the page. Ajax will work only on the more advanced browsers (6.x or higher).
In traditional Web applications, the interaction between the server and the user is synchronous. When a user performs an action, the action triggers a request to the server, which renders the appropriate page in the user's browser. The user must then wait for the page to load while the request is being processed. Each action a user performs results in lag time. Once the request is processed, the server sends the results back to the user.
With Ajax, the interaction between the server and the user is asynchronous. JavaScript that is loaded when the page loads handles most of the basic tasks such as data validation and manipulation, as well as rendering the page. While the JavaScript is rendering the page for the user, it is simultaneously sending data back and forth to the server. But the data transfer is not dependent upon actions of the user. Therefore, the normal lag and delay caused by server calls is eliminated because the information is being sent asynchronously via JavaScript calls.
