The Conference 2009 – Las VegasMarch 11-13, 2009 Ajax Defined  Ajax is several technologies, each flourishing in its own right, coming together in powerful new ways. Ajax incorporates: standards-based presentation using XHTML and CSS; dynamic display and interaction using the Document Object Model; data interchange and manipulation using XML and XSLT; asynchronous data retrieval using XMLHttpRequest; and JavaScript binding everything together.

The Conference 2009 – Las VegasMarch 11-13, 2009 Ajax Advantages  Based on open standards  Can decrease bandwidth by only updating content that needs to be updated  Allows sites to be more interactive, yet quicker than static sites  Reduces connections to web servers (i.e..css file only needs to be requested once)
