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 morena dds default or need to install separately?

"Multiple machines" work out-of-the-box with ROS 2, provided they are all in the "same network" (for the naive/simple case). There is no special configuration.

I don't understand what this means.

DDS is not used in ROS Melodic. Melodic is a ROS 1 release.

Bouncy is the current ROS 2 release. That uses DDS. No ROS 1 release uses DDS (by default: there is a rather experimental ROS 1 DDS transport if you search for it).
