Ajax is an amalgamation of several technologies that eliminates the loading of pages on the web by populating data on the click of a button by expanding the page.

Advantages of using Ajax

• Ajax avoids the tedious process that is the bane of most web applications. The part where an hourglass appears as the Web application consults the server and waits for a response.
• Ajax allows a web application to request only the content that needs to be updated, thus drastically reducing bandwidth usage and load time.
• This allows the portal to be more interactive and to respond quickly to requests.
• Browsers usually perceive the application to be faster or more responsive if it is Ajax driven.
• Server connections are drastically reduced by the use of Ajax.
