Asynchronous Messaging



Week 3 studio


What is Asynchronous Messaging?

Most People in an asynchronous messaging system don't have to wait for a response from the recipient, because they can heavily rely on the messaging infrastructure to ensure delivery.

This is a vital ingredient in loosely coupled systems such as emailing, faxing and even on blogs because it allows participants to communicate reliably even if one of the persons is temporarily offline, busy, or cant get on contact with.

Modern e-mail systems are based on a store-and-forward model in which e-mail computer server systems, accept, forward, or store messages on behalf of users, who only connect to the e-mail infrastructure with their personal computer or other network-enabled device for the duration of message transmission or retrieval to or from their designated server. Rarely is e-mail transmitted directly from one user's device to another's.
