Push technology

A server push is a method of Internet communication where an exchange of information request is initiated by the publisher or central server, rather than the client.

How does it work?

Like the push function used in programming, push technology services are often based on information preferences that were previously established. This model is called publish/subscribe. For example, a client "subscribes" to one or more information "channels" offered by a server. Ten, whenever new content is available on one of the subscribed channels, the server "pushes" that information to the client device.

Examples of push technology

A common example of a service that utilizes push technology is any two-way chat program, such as Instant Messenger. Chat messages and sometimes attachments are sent to users as soon as they are received by the messaging service. Other uses of push technology with web applications include stock tickers, online betting and auction sites, and online chat systems.
