Any Computer Language can be defined in terms of its  Vocabulary  and it's  Grammar . A Language's grammar specifies the rules of composition of its fundamental elements. When you start learning a language most of the introductory material focuses on the vocabulary and the grammar.

Furthering its vision to organize knowledge on the net, Google developed services like Gmail, Calendar and now Google apps. However, this is all on the server side. Client side has traditionally not been a strong hold of Google. With release of Google desktop, Google declared its presence on the client side. Technologies like Google Gears are already in place to be used by the developers to develop offline applications, that automatically synchronize themselves online. To create a strong presence on the client side, Google needed its own browser. Chrome has finally emerged after gestation period of two years. As you know, Internet Explo
