. 1. Foreword, getting familiar with the Google Talk service:

The Google Talk client is a software application that enables its users (people with Google accounts) to instantly communicate with each other via voice calls and instant messages. A very interesting feature, something like an innovation from Google, is that the Google Talk service supports the different industry standards. In other words, you can connect to the GT service using the official client, or you can use other Instant Messaging programs developed by third parties, or you can even set it up on your BlackBerry. The available clients besides Google's are Adium, Gaim, iChat, Kopete, Miranda, Psi and Trillian Pro. Nishihara

Google Talk has been the long awaited entry of this truly global company into the IM and Voice Over IP communications market, where names like MSN, AOL, Yahoo and Skype have already been dictating the game and competing for user's choice. Considering how intense this market is, Google's entry will make it even more competitive which is a foundation for developing better products for the end user.

As mentioned, GT offers Instant Messaging capabilities, combined with high-quality and easy to use Voice-Over-IP calls. The software is totally integrated with Gmail, so all you need in order to login is just your Gmail username (the string before @) and password. Once you have the client installed, you will be asked for your Google username and password to login.

Login and automatically, all your Google buddies will appear in the buddy list. Of course, there is an Add Friend button, a “Search all contacts” field which searches both your Google Talk and Gmail contacts, and a drop-down under your name that lets you set your available/unavailable status and messages. There's also an Inbox button which takes you to Gmail, plus Help and Settings. http://www.eventbrite.com/org/4855420683

3. The technology behind Google Talk:

The developers of Google Talk have employed the open source XMPP protocol for the instant messaging feature, while the VoIP functionality is based on another protocol known as Jingle. Those are the publicly known facts, but Google hasn't disclosed any information on the technology behind their server network.

XMPP stands for Extensible Messaging and Presence Protocol, open source protocol based on XML, designed for real-time instant messaging. The exact definition of XMPP as given in RFC3921 is “a protocol for streaming XML [XML] elements in order to exchange messages and presence information in close to real time.” Blogging For Bucks How To Start Making A Real Coping With Your Site And Get Freedom..
