What is a node in Selenium Grid?
Node is the machine which is attached to the hub.
There can be multiple (preferably) nodes in Selenium Grid.
Selenium Grid uses a hub-node concept where
you only run the test on a single machine
called a hub, but the execution will be done
by different machines called nodes.
