What is the difference between "-role node" and "-role webdriver" in selenium grid ?

i.e.

is there any difference between

java -jar selenium-server-standalone-2.16.0.jar -role node -hub http://a.b.c.d:4444/grid/register

and

java -jar selenium-server-standalone-2.16.0.jar -role webdriver -hub http://a.b.c.d:4444/grid/register

?

I did not find any difference, but there should be some. Did you check online docs? What do they say?\ - Pavel Janicek
I found the answer: Before, you needed 2 different nodes to have legacy ( rc ) and webdriver support. Now, A single node can handle both, so "rc" and "wd" have been replaced by "node". - Shantanu_O9O9

Ok..I got the answer :)

The following lines throws light on my question :

For backwards compatibility "wd"(webdriver) and "rc"(remotecontrol) roles are still a valid subset of the "node" role. But those roles limit the types of remote connections to their corresponding API, while "node" allows both RC and WebDriver remote connections.
