Node.js is an event driven web server. In layman's terms, that means that a server doesn't need to tie up resources unnecessarily for every device that wants to receive updates. Instead, the server can respond specifically to the events that actually require a response and only bother updating the clients that should know about it. That means more timely updates in a way that can scale.

Zivtech is leveraging Node.js by developing the Node.js module for Drupal, which provides a Node.js server that can allow your users to get updates in real time from your Drupal site, and potentially from other software and platforms (such as mobile)!
