Information technology rules this world. But one of the main apprehensions of information technology is making these technologies as competent as possible. It is a decisive factor in the success of organizations in this world of cut-throat competition. These organizations are now heavily dependent upon applications and operating systems which are stored and used over the Internet. It is very difficult to run applications on a wide array of platforms and for different purposes. On the other hand, there are technologies like Flash and Java Applets which have strived hard to provide web applications with more user-friendliness and dynamism.

Some of the other drawbacks of today’s web applications are the traumas experienced from page reloading and refreshing delays. But the technologies included in Ajax (Asynchronous JavaScript and XML) facilitate the task of web applications so that they can operate speedily and in a hassle-free manner for varieties of circumstances without the problem of page-loading delays.

The main use of Ajax is for web development. This term was brought to limelight by Jesse James Garret in the year 2005. It is not a totally new phenomenon. You can say it is a new practice. It is a blend of a number of well-known technologies. Various components of Ajax include Extensible Hypertext Markup Language (XHTML), Cascading Style Sheets (CSS) and Document Object Model (DOM) which is accessed with the help of a client-side scripting language such as JavaScript.

Ajax enables dynamic presentation of information and this leads to more interactivity. It has objects named XMLHttpRequest that allows asynchronous data interchange with web servers. The task of transmitting information between the server and the client is accomplished by XML which provides the format. In Ajax, the data can be formatted using server-side scripting. With the help of server-side scripting, the user requests can be processed by operating the script on the server itself. As a result, you can build interactive and dynamic HTML web pages. It is also employed to set-up and present the interface between a web page and a database. The technologies used in Ajax are not new and tried and tested in different conditions.

The main contribution of Ajax to this web world is the richness of user-experience. You need a lot of applications to run a web page. As a result, you have to wait for a long period of time before all these applications get refreshed to display the entire web page. A decrease in the delay periods through Ajax can contribute immensely to the popularity of Internet and it can be all-pervasive.

Another benefit you can derive from Ajax applications is a reduced bandwidth use. The term bandwidth usually refers to the quantity of data that can be transmitted between user and website or server. In Ajax, bandwidth is used only in special circumstances and not every time a request is made. Contents are loaded only as per the request and the HTML code is generated from the local browser. Ajax also enables programmers to divide methods and setting up for particular information delivery functions over the Internet.
