Google talk

What is google talk?
Google Talk is Google's free chat and instant messaging application available on a variety of platforms including Android, Mac OS 10.5 or higher, Linux, Windows (Server 2003, XP and higher), and Google Chrome OS. Google Talk also has support for Voice over Internet Protocol (VoIP) or PC-to-PC calling. Mobile platforms like Android and BlackBerry include Google Talk on most compatible devices. Google Talk is also known as Gtalk.

Google Talk was launched in August 2005 and is now used worldwide, largely due to its easy integration with Google's Gmail platform which makes Gmail storage easier for Google Talk chats and messages.

Google Talk uses the open Extensible Messaging and Presence Protocol (XMPP), which enables live messaging and events including voicemail and offline messaging.

The innovative and cross-platform application features of Google Talk are as follows:

Can be launched in a browser, eliminating the need for download and installation. The browser version of Google Talk (available with Gmail and Google+) is an effortless and convenient option, but it doesn't include all of the functionality of the standalone version.

Provides basic file transfer functionality for the stand-alone client version only. Files cannot be transferred to users of the browser version.

Chat - Users can send instant messages (IM) and Gtalk invitations to Gmail users and contacts. As of October 2011, video chat will be available when used in Gmail. However, this feature is not included in the downloaded client version.

Includes Voice over Internet Protocol (VoIP) features such as audio conferencing and file transfers.
