Google talk

Google Talk
Google Talk (GTalk) is a free Windows and web-based application for instant messaging and voice over internet protocol (VOIP), offered by Google Inc. The first beta version of the program was released on August 24, 2005.

Instant messaging between the Google Talk servers and its clients uses an open protocol, XMPP, allowing users of other XMPP clients to communicate with Google Talk users. VoIP in Google Talk is based around the Jingle protocol. The technology used within the Google server network however is not publicly known.

The Google Talk client is only available for Microsoft Windows (2000, XP, Server 2003, and Vista). Mobile clients are also available for the BlackBerry, iPhone and T-Mobile G1. With the release of the Google Talk gadget, users of all platforms supported by Adobe Flash Player can also use Google Talk.[1] Many other XMPP clients are compatible with Google Talk, and support a variety of other platforms.

Labs edition
Google has released a new version of Google Talk called "Google Talk, Labs edition." It still currently lacks many features of Google Talk's 'stable' releases. The features it lacks include File Sharing and Voice Chat. It features rounded alerts for new email. It can have multiple tabs with group chat, private chat and the regular screen open at once. It is available for free download here: http://www.google.com/talk/labsedition/. Flash Player will be required to install, and upon first launch, a new flash-plugin will need to be downloaded. This edition is not meant for general use, hence the reason why it is a labs edition. Labs edition also includes Google Update service
