Asynchronous can be defined simply as not synchronous. Synchronous communications work in a structured fashion, and the sender usually must wait for a response from the receiver before continuing. The opposite then would be a situation where the sender can continue on to other tasks without waiting for a response from the receiver. Think of it like voice mail versus a telephone conversation. When you leave a voice mail, the target does not have to hear it or respond to it immediately and you can go on to other tasks. When you are having a conversation on the telephone, it would be rather discourteous for you to say what you have to say and then hang up without waiting for a response. Asynchronous communications work like the voice mail example, and synchronous communications work like the live telephone conversation. Asynchronous communications provide a mechanism for requests to be processed when the receiver has the time and ability to process them. Synchronous communications usually require “right now” processing.
