Push and Pull Technology
Internet content can be delivered in one of two ways: push or pull. In the push method, the web server initiates contact with the client (your workstation) when new information is ready to be transmitted. As long as there is an active
internet connection, information can be pushed to the client from the server.
In the pull method, the client asks the server to send any new information.
