ITPEC FE Morning October 2022 Question 10
ITPEC FE Morning October 2022 — Question 10 of 80
Ajax (Asynchronous JavaScript and XML) — dynamic UI updates without full page reload.
Ajax uses JavaScript's asynchronous communication (e.g., XMLHttpRequest, fetch()) to exchange data with a server in the background and update parts of the page dynamically.
Why not others:
- (b) CSS — styling language for layout and appearance, not communication
- (c) RSS — Really Simple Syndication, a feed format for content distribution
- (d) SNS — Social Networking Service, a platform category (e.g., Facebook, Twitter)
Key point: Ajax = asynchronous server requests + partial page updates, no full reload.
