Clarification about transport and http module

Elastic Stack Elasticsearch
1

Hi,
Would be great if you can help clarifying below query -
Elasticsearch transport module is used for internal communication between elasticsearch nodes and uses the port 9300.
Elasticsearch http module is used for communication for external entities like logstash & kibana to communicate with elasticsearch and this uses the port 9200 (by default).
Is my understanding correct?
If not, can you explain how do logstash or kibana communicate with elasticsearch?

Thanks,
Shivani
