Which of the following digital communication technologies use asynchronous communication?

1.Forums

2.Video conferencing

3.Email

4.Instant messaging

A1 & 2 only

B1 & 4 only

C1 & 3 only ✓ Correct

D3 & 4 only

Correct answer: (C) 1 & 3 only

Explanation

Statement 1 is true because forums are asynchronous, with posts and replies made at different times.

Statement 3 is true because email is asynchronous, as the recipient reads and replies whenever convenient.

Statement 2 is false because video conferencing is synchronous, happening live in real time.

Statement 4 is false because instant messaging is synchronous, with an immediate back-and-forth.

Asynchronous communication does not require both parties online at once.

This flexibility suits messages that do not need an instant response.
