Question

Which statement about synchronous communication is true?

Answer 1

In general, synchronous communication means you have to wait for the answer all the time. The programming logic is simpler, but the cost that you spend a lot of time waiting.

If the options are:

a. The people communicating don't need to be online at the same time.
b. There is lag time in the communication.
c. The communication occurs in real time.

a is false, you do need to be online to receive the message
b is true, typically you continue only after an acknowledgement
c is true, you wait for acknowledgement that occurs in real time (not necessarily fast though)
