push technology - Computer Definition
A data distribution technology in which selected data are automatically delivered to the user's computer or mobile device in real time or at prescribed intervals. E-mail messages, calendar updates, text messages, information and advertisements are examples of data that are pushed to the user. Although updates to applications are, in fact, regularly pushed to the user's device if the user selects the option, that service is called "automatic updating." The term push generally applies to data and media. Contrast with "pull technology," in which the user initiates a request for the data each time. Browsing the Web is an example of the pull model. A Form of Real-Time Transmission If data are sent to the receiving party at the moment they are generated, then the push technology is also real-time transmission. See real time.
