Quizplus · Accepted Answer

An asynchronous message is shown as a half arrowhead in a sequence diagram, and it indicates that the sender does not have to wait for the recipient to handle the message. In contrast, a synchronous message (C) requires the sender to wait until the recipient has handled the message before continuing with the sequence. Activation (B) represents the calling of a method or function, but does not indicate the type of message being sent. Simple messages (A) are a general term for any message in a sequence diagram and do not represent a specific type of message.
