Push Technology

Push technology is a communication paradigm where data updates are initiated and sent from a server to clients without requiring explicit requests from those clients. This contrasts with traditional pull/polling models where clients must repeatedly ask for updates. It enables real-time data delivery for applications like notifications, live feeds, and collaborative tools.

Also known as: Server Push, Push Notifications, Real-time Push, Web Push, Push Protocol

Why learn Push Technology?

Developers should use push technology when building applications requiring instant data updates, such as chat apps, live sports scores, stock tickers, or IoT monitoring systems. It reduces latency and server load compared to polling, making it ideal for real-time features where users need immediate information without manual refreshes.
