Techopedia Explains Presence

The most common example of presence is the status messages presented for users in an instant messaging system, which may read “available”, “busy”, “offline” or “out to lunch”, among other statuses. This indicates a user’s current communication status. Presence is often set by the user, but can also be used by technology to infer the user’s state. As such, comprehensive presence information that integrates various technologies (such as the person’s calendar and mobile devices) can have privacy issues.
