information about rosnode

edit

Hi,

Hope everyone is fine here. I just need a little help about rosnode. I am using some pre built nodes and integrating them on to my system. On the terminal when I type in this command " rosnode info nodename", it gives me some information about the node that is the subscriptions, services, publications and connections. Below I am just typing in the Connections. That would be great if someone can help me in understanding what does each line means in the below lines.

Connections:
* topic: /mavlink/from
    * to: /mavlink_bridge
    * direction: outbound
    * transport: TCPROS
* topic: /rosout
    * to: /rosout
    * direction: outbound
    * transport: TCPROS
* topic: /gps/fix
    * to: /gps
    * direction: inbound
    * transport: TCPROS
