Services

Which of the following statements about services are correct?

SOLUTION:
  • Services are similar to topics in that they facilitate the passing of messages between nodes.
  • Services use a request-response message passing scheme, rather than the pub-sub method used with topics.
  • A request message on a service might actually trigger a new sensor measurement, like a new camera image, with settings like exposure time specified in the message.
