2. What are the differences between Selenium 1(aka. Selenium RC or Remote Control) and Selenium 2(aka. Selenium Webdriver)?

Selenium 1 doesn't talk to the browsers directly and it is based a typical client-server architecture.

Selenium 1 components are:

1) The Selenium Server which launches and kills browsers, interprets and runs the Selenese commands passed from the test program, and acts as an HTTP proxy, intercepting and verifying HTTP messages passed between the browser and the AUT.
2) Client libraries which provide the interface between each programming language and the Selenium RC Server.

Selenium 2 interacts directly to the browser using the ¡®native¡¯ method for the browser and operating system, thus avoiding the restrictions of a sandboxed Javascript environment.
