Which of the following is an example of push technology?

Push technology is a communication method whereby information is automatically delivered to users without them having to request it. This means that the system proactively sends updates or notifications to the user.

In the case of an e-mail health alert, the system sends information directly to an individual's inbox, notifying them of important health updates or alerts without requiring the individual to check or search for this information. This direct delivery exemplifies the essence of push technology.

In contrast, other options involve user-initiated actions. Patients bringing printouts are actively retrieving information rather than receiving it automatically. Searching on Google requires the user to input queries and look for information, indicating a pull strategy rather than push. Sending a consultation on request also involves the user taking action to request information, which further illustrates a pull method.

Overall, the concept of push technology emphasizes the direct and unsolicited delivery of information, clearly demonstrated by the e-mail health alert.
