What is the difference between asynchronous and synchronous communication?

AAsynchronous is real-time communication, while synchronous is one-way technology

BAsynchronous is communication that does not occur at the same time, while synchronous communication occurs at the same time ✓ Correct

CAsynchronous communication includes instant messaging, while synchronous communication includes email

DAsynchronous communication is fast and instant, while synchronous communication is collected at a single point in time

Correct answer: (B) Asynchronous is communication that does not occur at the same time, while synchronous communication occurs at the same time

Explanation

Asynchronous communication does not happen at the same time, while synchronous communication happens simultaneously between the parties.

The claim that asynchronous is real-time and synchronous is one-way reverses the actual meaning.

Pairing asynchronous with instant messaging and synchronous with email is wrong, since it is the other way round.

Calling asynchronous fast and instant while synchronous is a single point in time misdescribes both.

Email and forums are asynchronous because replies come at different times.

Live chat, phone and video calls are synchronous because participants respond in real time.
