Asynchronous messages are instantaneous,there is no lag between when the message is sent and when it is actually received.​

Asynchronous messages are not instantaneous and there may be a lag between when the message is sent and when it is actually received. This is because the recipient may not be immediately available to receive the message, or there could be delays in the communication channel. Asynchronous messages are designed to be sent and received at different times, and the sender does not need to wait for a response from the recipient before proceeding.
