UML Sequence diagrams are interaction diagrams that detail how operations are carried out. An actor serves the performance, which associates external behavior or subjects and human users. These can help to predict how a system will behave and to discover responsibilities a class may need to have in the process of modeling a new system. We can see here how the HTTP clients have become participants of the sequence diagram with its own lifeline, where we visualize the messages sent and received to represent the network calls we do. A role played by an entity that interacts with the subject is called as an actor.
