Final answer:
The true statements about synchronous and asynchronous communication are: Synchronous communication requires participants to be online at the same time, whereas asynchronous communication does not allow real-time interaction and is not limited to face-to-face conversation.
Step-by-step explanation:
The student asked which two statements about synchronous and asynchronous communication are true. Statement A, which states that synchronous communication requires participants to be online simultaneously, is correct. This form of communication is exemplified by live video conferences, telephone calls, or chat rooms. On the other hand, statement B is incorrect because asynchronous communication does not allow for real-time interaction; it allows participants to communicate at their convenience. Hence, statement C is also untrue for synchronous communication, as it does not enable participants to communicate at their own pace. That characteristic applies to asynchronous communication. Lastly, statement D is false since asynchronous communication is not limited to face-to-face conversations; it also encompasses emails, forums, and voicemail, where responses do not occur in real time.
Synchronous and asynchronous modes of communication are increasingly important as we are connected now than ever before and make use of various technologies to facilitate collaboration and information sharing, even over long distances. Defining the modes of communication and the expectations they entail are essential parts of successful collaboration.
