  • ROS Master manages the communication between nodes

  • Every node registers itself at startup with the master

  • Start the master with ROS core

If ros master is not running then you cannot do the rosrun and nodes will not work

If the master gives the permission to the nodes then the nodes will communicate with each other.To run the ros master we have to enter 

roscore

in the terminal.
