5. How Ajax work
AJAX = Asynchronous JavaScript And XML
• Asynchronous, event-driven programming model (Wikipedia - Event-driven programming, n. d.)
• Well-suited for creating desktop-like graphical user interfaces
(Wikipedia - Graphical user interfaces, n. d.)
• Full HTML page load only at startup
• After that, only incremental page updates (steps 1-4) (Rose India, 2006)
