ITPEC FE Morning April 2021 — Question 10 of 80

Ajax (Asynchronous JavaScript and XML) — technology for dynamic UI without page transitions.

Ajax allows a web page to send and receive data from a server asynchronously using JavaScript — without reloading the entire page.

  • •Ajax — uses XMLHttpRequest or fetch() to communicate with the server in the background
  • •CSS — stylesheet language for visual presentation, not communication
  • •RSS — Really Simple Syndication; a format for distributing content updates (news feeds)
  • •SNS — Social Networking Service; platforms like Facebook or Twitter

Key point: Ajax = asynchronous + JavaScript + no page reload → dynamic UI updates.
