Quizplus · Accepted Answer

An asynchronous message is one in which the caller does not have to wait for the receiving object to finish executing the called operation before it can resume execution itself. The opposite of an asynchronous message is a synchronous message, which requires the caller to wait until the operation is completed. Therefore, the best choice is A, asynchronous message. B and D are not relevant and C is the opposite of the correct answer.
