1,2 and 3 are few of the many things which have a 4 letter name you would have heard a 1000 times over the past year or so.

What is it? ( and identify 1,2,3)

1. 2.

3.

Cracked by everyone who tried. Namely, Quehin , SidSen , srichand , jayanth , bs , Atul Mathew , vaibhav008 , Ganesh Prasad , Srivatsa , iamniks , Keerthi Kiran M , rajeshvj , sharath , udupendra , Gammafunction , Madan , shivathilak , Abhishek , Tathagata Chatterjee , prasanth , yaksha and nihit.

AJAX: Asynchronous Javascript and XML is the answer. It has been the buzz word of the web 2.0 era, with every site (including mine) flaunting Ajax capabilities more as a fashion statement than need :)

Lemme quote Srichand’s answer for details

“The first chap is Ajax , the son of Telamon and Periboea and king of Salamis.

Second picture, is the city of Ajax, in Ontario Canada, famous for Sum 41 the band

The third picture, is… well, Ajax, the arcade game.

The title, refers to the message shown when gmail loads up.. Gmail of course, is the most popular Ajax application around.”

My other favourite Ajax products are :D

and the AJAX company which is a competitor of ACME corporation :)
