AJAX: An acronym derived from "Asynchronous JavaScript and XML." AJAX is an important underlying technology used to create interactive Web applications. Ajax is what enables Web 2.0 sites to behave dynamically, so that they feel more like computer programs than static web pages. Like the way Google Maps lets you drag elements across the page? That's AJAX in action.
Atom: A format for the syndication of online content, atom functions as a newer alternative to RSS (described below).
Blog: Originally derived from the word "weblog," a blog is a simple content website created with inexpensive self-publishing tools. Blogs are the backbone of Web 2.0's democratic spirit.
Mashups: Websites or applications that combine content from one or more sources. For example, Cellreception.com combines Google Maps with a database of 124,000 cell phone tower locations to help users determine where mobile coverage is strong — and where it isn't.
RSS: Shorthand for "Real Simple Syndication," RSS is a protocol that makes it easy for computer users to receive content from their favorite providers whenever the content is updated. Instead of having to remember to visit a website to read a favorite column, watch a video, or listen to an audio program, RSS lets a user subscribe to the content so it's delivered automatically. The flow of content the user receives is called an "RSS feed."
Social media: A generic term used to describe Web-based tools that harness the power of collaboration and group interaction. This can take many forms, from the personal web pages of MySpace to the virtual worlds of Second Life to the professional networking popular on LinkedIn.
Tags: User-generated keywords used to describe online content. Tags make it easier for both humans and search engines to find relevant and related information.
Wikis: A dynamic Web document that allows users to add, change, or edit the content displayed on the page. The user-created Wikipedia online encyclopedia is the most famous example.
XML: An abbreviation for "Extensible Markup Language," XML is a programming code for online data that preserves the structure and formatting of a digital document regardless of whatever application is used to read it. XML is an important enabling technology for RSS feeds (described above).
