“When it comes to data delivery from the server to the client, we are limited to two general approaches: client pull or server push. As a simple example with any web application, the client is the web browser. When the website in your browser is asking the server for data, this is called client pull. The reverse, when the server is proactively pushing updates to your website, it is called server push.”
