how to organize data transfer between nodes on multiple PCs on ROS2

in ROS1 (melodic morena) it was simple and clear to do it. we ran roscore on one PC and connected to it from other PCs. But in the second version as far as I know there is no roscore, and I do not quite understand how to now implement data exchange.


just a small question does rock melodic moreana ds default or need to install separately?
