Ajax, the name given to the combination of Asynchronous JavaScript and XML, allows Internet users to perform particular requests by creating active web applications. This application synchronizes different tools in order to perform the user’s request. The tools that are used by this application are XML, JavaScript, DHTML, CSS, DOM, and XMK Http Request, all of which are created by Microsoft. All of these tools work together in order to allow the request of the user to open in the browser window they have open, rather than making the user wait for a totally new page to load.

Ajax operates by the use of an engine acting as a middle man between a user’s browser window and the Internet server from which the user is requesting information. Instead of loading a new page or letting a new window open, the Asynchronous JavaScript and XML application initiates its own engine to display the image seen by the user. JavaScript delivers the messages from the user’s interactions with the webpage, to the engine of the application. The Asynchronous JavaScript and XML engine is what makes the application work instantly without the need for new pages or browser windows to load.

Ajax is now used by a multitude of websites in order to offer services to website users quickly and efficiently. One example is the website Google Maps. By using Asynchronous JavaScript, the maps and other relevant information load in real time. This action alleviates the information from having to open in a new browser window and allows it to load much more quickly. This ability is greatly appreciated by most website users, as they can gain their information quickly and easily. Today, Asynchronous JavaScript works with most web browsers, but this was not always the case. At one time, it could only be used by Internet Explorer.

It took some tweaking to allow Ajax scripting to work with other web browsers besides Internet Explorer and on other operating systems besides Microsoft Windows. Once the application was expanded for use to other browsers, it also was designed so that a new download did not have to be prompted in order for the application to be used. This was done by writing the application into HTML or JavaScript code. With these tweaking techniques came the ability for more individuals to use the application.
