How are Selenium-server-standalone jar and Selenium Client WebDriver different from each other

Question

Can someone tell me what the differenes are between 'Selenium-server-standalone.jar' and 'Selenium Client & WebDriver' from implementation perspective? The link to download the two JARS are below.
http://selenium-release.storage.googleapis.com/2.44/selenium-server-standalone-2.44.0.jar & http://selenium-release.storage.googleapis.com/2.44/selenium-java-2.44.0.zip

I'm aware that the  first version was Selenium RC and the second version is Selenium 2.0(Webdriver). So, my question is, does the latest version include all the JARS required to run even Selenium RC(Selenium Server). And vice versa, does Selenium Server JAR support all the methods run as part of Selenium Webdriver? What are the differences between these two JARS?

Answer 1

Okay, your understanding of "Selenium Server" & "Selenium WebDriver" is wrong.

Selenium Server: This Was extensively used in Selenium RC for performing local and remote tests because of Same Orgin Policy. However, in Selenium WebDriver, there is no need for Selenium Server JAR for performing local tests. Only for remote tests using Grid, it is needed.

And with the other zip package, we have all the classes & methods as libraries for allowing Selenium WebDriver to achieve automation while testing the web pages.
